Product Description

The HMHG-III series harmonic reducer has a compact structure with a through-hole. The wave generator has a large diameter hollow shaft with cross roller bearings to withstand radial and axial loads. This institution is simple and convenient for users to install customly.

Principle of harmonic gear transmission

The harmonic gear drive was invented by the American inventor C.W.Musser in 1955. It is a new transmission mode using the elastic deformation of flexible working components to carry out movement or power transmission. It breaks through the mode of mechanical transmission using rigid components and uses a flexible component to achieve mechanical transmission. Thus, a series of special functions that are difficult to achieve with other drives are obtained. Because the deformation process of the intermediate flexible component is basically a symmetrical harmonic, it is named. In addition to the Soviet Union called this transmission waveform drive or flexible wheel drive, the United States, Britain, Germany, Japan and other countries are called “harmonic drive”.

Harmonic deceleration principle
The deceleration principle of harmonic gear transmission refers to the use of the relative motion of the flexwheel, rigid wheel and wave generator, mainly the controllable elastic deformation of the flexwheel to achieve motion and power transmission. The elliptic CAM in the wave generator rotates in the flexwheel so that the flexwheel deforms. When the flexwheel teeth and rigid wheel teeth at both ends of the long axis of the elliptic CAM of the wave generator are engaged, the flexwheel teeth at both ends of the short axis are detached from the rigid wheel teeth. The teeth between the long axis and the short axis of the wave generator are in a semi-meshing state that gradually enters the snapping along different sections of the perimeter of the flexwheel and the rigid wheel, which is called the snapping; In a semi-meshing state that gradually withdraws from engagement, it is called snapping out. When the wave generator continuously rotates, the flexwheel constantly deforms, so that the 2 wheel teeth in the biting, meshing, biting out and disengaging 4 kinds of motion constantly change their original working state, resulting in the wrong tooth movement, to achieve the active wave generator to the flexwheel movement transmission.

The Importance of an Agricultural Gearbox

The role of an agricultural gearbox is crucial to the production of food. They play a crucial role in agricultural equipment, and are needed at every stage of the food chain. As the population increases and the need for food rises, gearboxes are increasingly becoming a critical component of heavy-duty equipment. To maintain a high quality, agricultural gearbox, replacements must be available at a reasonable cost. In addition, they need to be easily accessible.

Bevel gearboxes

A durable bevel gearbox is a critical component of any agricultural gearbox. The mechanisms and materials used to make the device will determine its durability. Investing in a long-lasting gearbox will save you the trouble of replacing it later. Bevel gearing is one of the most common types of mechanical gearing, and its advantages are many. A durable gearbox is reliable, easy to use, and cost-effective, ensuring that you will never have to replace it.
Bevel gearboxes are available in different tooth shapes and sizes, and are typically realized with straight or helical teeth. Bevel gearboxes can be either parallel or oblique in direction, and their axes can intersect at 90 degrees. Bevel gearboxes can have opposite or parallel output shafts, and the direction of the drive and output shaft can be the same or opposite, depending on the installation.
A tractor PTO can be a powerful source of torque, but it can only transmit the same amount of torque at slower speeds. Agricultural implements, on the other hand, use chains and pulleys to transmit their torque. This type of heavy-duty gearing is essential for the heavy-duty demands that agricultural implements place on them. Although geared agricultural applications are the most common, they are not limited to agriculture. Most agricultural gearboxes are used in wheel drives and massive torque low-speed applications.
Bevel gearboxes for agricultural machinery applications have several characteristics that make them useful. A right angle gearbox, for example, is well suited for use with offset rotary fillers and hollow output shafts. It offers a reduction ratio of up to 2.44:1, has a cast-iron case, and delivers power up to 49kW. It is designed for small agricultural work, such as crop treatment, soil preparation, and cement mixers.

CZPT gearboxes

There are countless reasons why CZPT agricultural gearboxes are so important. Global population is increasing by 80 million people per year, and that demand is only expected to continue rising. In addition to a constantly growing population, cropping cycles are getting shorter, putting even more strain on farm machinery, including gearboxes. Fortunately, CZPT offers a variety of solutions to maintain and repair your equipment, from on-site repairs to storage options.
Agricultural gearboxes are essential to the cropping process, and CZPT reducers perform a variety of critical tasks. The reversing gear, for instance, helps reduce friction and increase efficiency. The reversing gear is usually made of ball bearings, and is available in various versions and power capacities. Agricultural gearboxes are essential for a number of tasks, including a tractor’s ability to pull a tiller.
In the agricultural industry, a CZPT ag-class reducer powers a beet truck’s conveyor. Its durable helical gearing and grease-purged Viton seals keep it working properly for years. CZPT Ultramite gearmotors can be used to power pilers, stackers, and hoists. They generate low speed directly and can also support high-speed pinions.

Closed-loop seals

A closed-loop seal is an excellent alternative to desiccant breathers, which can lead to contamination. A closed-loop seal can isolate a gearbox from the atmosphere, ensuring that no moisture or contamination can enter. This is essential for the safety of the equipment. A closed-loop elastomeric seal prevents water from entering the gearbox, preventing contamination and lubrication from escaping.
These high-tech seals combine service life and reliability, enabling new breakthroughs in agriculture, infrastructure and transportation. Moreover, these high-performance mechanical drive components are an essential part of breakthroughs in industries like energy, agriculture and transportation, as well as global megatrends like digitalization. As a result, they extend the life of agricultural gearboxes. But how do these high-tech seals perform?
A closed-loop seal is critical for agricultural gearboxes, as they keep the lubricants and gases in the gearbox. They are essential for the entire food chain, as even a little bit of downtime can cut production costs. This is why a high-quality agricultural gearbox is essential for safety and easy maintenance. To ensure a high-quality, long-lasting performance, closed-loop seals should be a standard feature.
Another improvement over single-lip designs is the inclusion of a dust-lip. The outer lip of the closed-loop seal can be damaged by temperature and contaminants. Once the outer lip fails, debris will accumulate against it and under it, causing a leak and seal failure. When this happens, it’s too late to repair the seal. You’ll need to invest in a new agricultural gearbox, and you don’t want to waste money on an expensive failure.

Surface finish

An agricultural gearbox should be free of mechanical damage and casting defects. Surface finish should be as close as possible to 76. The distance between shafts and bearing housing must be within six millimeters and the surface finish should be smooth. In addition, the shaft surface finish should not exhibit any ellipticity or directional pattern. A smooth surface is comfortable to operate. In this way, it improves the quality of comfort while driving.
There are various types of gears and their surface finishes. For example, bevel gears, sun gear drive, and planetary gearbox are common in agricultural applications. The surface finish of agricultural gears varies depending on the type of material used. In certain industries, gears can be subjected to low torques and strong forces. However, in agriculture, gears are subjected to specific conditions such as dustiness and contaminated water.
Various studies have been conducted to study the effectiveness of various surface finishes. Some of these studies have focused on the quality class of honed wrought steel gears. However, results were inconsistent. It was determined that the difference in the quality class of honed wrought steel gears was less than 3%, which was within the acceptable range of errors in the assembly process. However, it remains important to note that a high quality surface finish is crucial for a high gearbox’s performance.
Stream finishing has proven to be more effective in enhancing surface finish. Compared to honing and grinding, Stream finishing produces a smooth surface that is two to four times better than conventional finishes. The benefits of this method include high-quality metal and reduced waste. The process of isotropic superfinishing makes a gearbox more efficient than other manufacturing processes. In addition, it improves the lifespan and durability of its components.

Cost

Agricultural gearboxes are critical for the production of the food we eat. With heightened food demand, a worn out gear will lead to increased equipment wear and downtime, resulting in significant losses for farmers. Agricultural gearboxes should be of high quality, as they are critical for the whole food chain. These gears can be costly to replace and can cause significant downtime, resulting in a failure to meet the demand.
To determine the cost of an agricultural gearbox, you need to compare the prices offered by different manufacturers. If you’re planning to purchase a new agricultural gearbox, look for one that’s manufactured by an authentic equipment manufacturer such as CZPT. Don’t settle for a gearbox that’s not manufactured by an OEM, as it won’t last long. Also, check the safety section of the manufacturer’s website for advice on selecting a gearbox for your needs.
