Construction Machinery Gears
Classification By Appearance Features
Cylindrical gear: The most common type of gear, used for transmission between parallel axes, is shaped like a cylinder, and the teeth are distributed along the axis of the cylinder. According to the different direction of the teeth, it is divided into straight gear and helical gear. The tooth direction of the spur gear is parallel to the axis, the structure is simple, the manufacturing cost is low, and it is suitable for medium and low speed transmission; Helical gear tooth direction and axis are at a certain Angle, good meshing performance, large contact degree, strong bearing capacity, suitable for medium and high speed transmission.
Mechanical parts bevel gear
Worm gear: A special type of gear used for transmission of vertical or inclined shafts. The tooth direction of the worm gear is spiral, while the tooth direction of the worm is opposite. This type of gear is often used for deceleration or acceleration drives, with high transmission efficiency and self-locking, and can work in harsh environments.
Machine parts worm gear(Classification by material)
Metal gear: usually made of steel, cast iron, brass and other materials, with high strength and wear resistance, suitable for a variety of mechanical transmission needs. According to the different manufacturing process, metal gear can be divided into casting gear, forging gear, cutting gear and so on.
Non-metal gear: usually made of plastic, wood, glass and other non-metal materials, with low cost and good corrosion resistance, suitable for some specific transmission occasions, such as plastic gear for light load and low speed occasions or corrosive media environment.
Classified by manufacturing method
Cutting gear: Made by cutting processing method, the precision and shape of the gear ca

Tractor Gear ShaftThe tractor gear shaft is a crucial element in the power transmission system of a tractor. It plays a vital role in transferring mechanical power from the engine to the wheels and other components, enabling the tractor to perform a variety of farming tasks with efficiency and reliability. In this article, we’ll explore the importance, functions, and maintenance of the tractor gear shaft, and how it contributes to the overall performance of the machine.

Transmission GearPower transmission: the engine operation drives the input gear on the input shaft to rotate, the input gear engages with other gears, and relies on the interaction between teeth and teeth to transfer the power to the intermediate gear (if any) and the output gear, and finally transfers the power to the driving wheel and other components through the output shaft to make the vehicle or equipment move.
Variable speed principle: Change the transmission ratio by meshing gears with different numbers of teeth. For example, when the big gear drives the small gear, the speed of the small gear will be faster than the big gear, but the output torque will be smaller, to achieve growth and torque reduction; On the contrary, when the pinion drives the big gear, the speed of the big gear slows down, the torque increases, and the torque increases. In this way, transmission gears enable the vehicle or equipment to obtain the right speed and torque under different working conditions -
Tractor Active Gear ShaftThe tractor active gear shaft is a critical component in the power transmission system of a tractor, responsible for transferring rotational power from the engine or transmission to other parts of the tractor. By efficiently distributing torque and enabling smooth gear shifts, the active gear shaft plays a vital role in enhancing the performance and versatility of the tractor, making it essential for a wide range of agricultural tasks. In this article, we’ll explore the function, benefits, and maintenance of the tractor active gear shaft.

Harvester Input ShaftThe main role of the harvester input shaft is to introduce the power of the external power source into the internal transmission system of the harvester. When the power source (such as an engine) is running, the torque generated is transmitted to the input shaft through the connecting parts, causing the input shaft to start rotating. The gear, pulley or sprocket and other transmission parts installed on the input shaft will rotate with the rotation of the input shaft, and then transfer the power to the subsequent transmission parts and working parts, such as driving the cutting device, conveying device, threshing device, etc., to complete the crop harvesting, conveying, threshing and other work processes.
