Selection method and usage precautions of worm gear reducer
Worm gear reducer is a power transmission mechanism that uses the speed converter of worm gear to reduce the rotation of the motor to the desired rotation and obtain a larger torque. It is mainly composed of transmission components such as worm gears, shafts, bearings, housings, and their accessories.

It can be seen in the transmission systems of various types of machinery, from ships, cars, locomotives in transportation, heavy machinery used in construction, processing tools and automated production equipment used in the machinery industry, to common household appliances, clocks and so on in daily life The application of reducers can be seen from the transmission of large power to small loads and precise angle transmission. In industrial applications, reducers have the functions of reducing speed and increasing torque. Therefore, it is widely used in speed and torque conversion equipment.

Advantages of worm gear reducer

(1) Cost saving, worm gear reducer with servo motor has lower cost than planetary reducer and servo motor;

(2) There are various installation methods that can meet the needs of customers on different mechanical equipment;

(3) Diversified speed ratios, with single-stage gear ratios up to 5-100;

(4) Worm gear reducer with self-locking function;

(5) High quality aluminum alloy casting shell with light weight;

(6) High speed ratio and low noise.

Selection method of worm gear reducer

(1) Determine the model and size of the required gearbox;
(2) Determine the reduction ratio and choose a reduction ratio that is as close to the ideal as possible. The calculation method for the ratio is: reduction ratio=motor speed (standard speed 1400)/reducer output shaft speed;

(3) Determine the torque (power) of the gearbox: Torque is crucial for the lifespan of the gearbox, and attention should be paid to whether the maximum torque value of the accelerator exceeds the maximum load torque of the gearbox;

(4) Determine the direction of the input and output shafts: The reducer has horizontal and vertical types, and the direction of the output and input shafts is: L direction: single input and single output, the right end is the input shaft, and the front is the output shaft; R direction: single in single out, left input shaft, positive output shaft; V direction: single input and double output, with the left input shaft and double output shaft on the front/back side; W direction: left and right dual input single output input shafts, positive output; F direction: dual input and dual output, input shaft at both ends, front/back output.

(5) Determine the size of the input hole and input flange;

(6) Determine the size of the output hole or output shaft;

(7) Check if other accessories are needed, such as torsion arms, output flanges, single and double axis outputs, etc.
 

Precautions for worm gear reducer

(1) Before using a worm gear reducer, check the form and structure of the reducer, transmission ratio, center distance, output shaft structure, connection method of the input shaft, and whether the output shaft direction of the input shaft is correct.

(2) Before use, check the oil level, which can be observed through the oil level static hole or by opening the oil plug.

(3) Before use, use the exhaust plug that comes with the gearbox instead of the sealing plug of the gearbox.

(4) Before use, gradually increase the load and do not start at full load.

(5) The gearbox should not be exposed to sunlight or harsh environments to avoid damage to the gearbox.

(6) The standard working environment temperature of the reducer should be maintained between -5 ℃ and 40 ℃.

(7) Maintain ventilation without affecting the heat dissipation of the motor fan.

(8) If the gearbox has been stored for too long, such as more than 4 months, check whether the oil seal is immersed in the lubricating oil and whether the oil seal has elasticity.
