In our daily life and work, we often hear the term “elevator.” In fact, an elevator is a type of lifting machinery that can vertically transport people or goods. In logistics systems such as factories and automated warehouses, it is also a key equipment for vertical conveying. On the elevator…
(The reducer) As an important transmission device, it is commonly used in scenarios with low speed and high torque. It can reduce the speed by engaging gears with fewer teeth on the input shaft with larger gears on the output shaft, thereby reducing the high-speed rotation of power sources such…
The types of electric motors are rich and diverse and can be classified in various ways. Firstly, according to the difference in working power supply, electric motors can be divided into DC motors and AC motors. Among AC motors, they are further divided into single-phase motors and three-phase motors. From…
The worm gear, as a unique gear with a special tooth shape that meshes closely with the worm in the mechanical transmission system, holds an indispensable position. When cutting the tooth part of the worm gear, it is generally accomplished with the aid of a powerful gear hobbing machine, mainly…
In the evaluation standard of gear accuracy, a total of 12 accuracy grades are stipulated. According to the order of accuracy from high to low, they are represented by the numbers 1, 2, 3… 12 in sequence. In practical applications, the commonly used accuracy grades are mostly between 5 and…
In mechanical transmission systems, when a motor is used in combination with a reducer, accurately calculating its output torque is crucial. So, how exactly should the torque of the motor combined with the reducer be calculated? First of all, we need to understand some key parameters. The motor power is…
In the vast field of mechanical transmission, worm and worm gear transmission, as a unique branch of gear transmission, exhibits significantly different characteristics from common gear transmission. Commonly speaking, ordinary gear transmission usually operates within the same plane to achieve power transmission in the same direction. This transmission method plays…
In mechanical equipment, (reducers) play a crucial role, and choosing the appropriate lubricating oil is crucial for the normal operation and long-term use of reducers. I. The lubricating effect of gear oil for reducers According to statistics, approximately 80% of component damage is caused by friction and wear. To a…
The plum blossom coupling, also known as the jaw coupling, is a widely used elastic coupling composed of two metal shaft sleeves and an elastic plum blossom spacer. It has excellent balance performance and is suitable for high-speed scenarios, with a maximum speed of up to 30,000 revolutions per minute.…
In the ideal principle of gear transmission, if it is assumed that the two gears undergo pure rolling without any sliding at the pitch point and the gears themselves are regarded as rigid bodies, then theoretically, there should be no efficiency loss in gear transmission. However, in the actual real…
