Motor with brake in rear end cap

Abstract

The invention discloses a motor with a brake in a rear end cap. The rear end cap is divided into a bearing chamber and a brake chamber, and a rotating shaft hole is formed between the bearing chamber and the brake chamber. The rear end portion of a rotating shaft penetrates the rotating shaft hole and is then placed in the brake chamber of the rear end cap, and space between the rotating shaft and the rotating shaft hole is sealed by a sealing ring. A bearing is arranged in the bearing chamber of the rear end cap, and an elastic component is assembled in a compressed way between the bearing and the rotating shaft hole. The brake is placed in the brake chamber of the rear end cap and installed in the rear end portion of the rotating shaft. The rear end cap is provided with an operation window in the side of the brake chamber. According to the invention, the rear end cap of the motor includes the brake, space between the brake and the bearing chamber is sealed, and influence of dust on a motor body is reduced. The operation window is reserved in the rear end cap, so that requirements for operating and adjusting the rear end of the motor are satisfied in real time in the motor using process. The structure is compact and simple, the occupation space is small, the motor weight is reduced, and the motor is light and convenient to maintain.

Description

technical field [0001] The invention relates to a motor with a brake, in particular to a motor with a brake in the rear end cover. Background technique [0002] With the wide application of automation and semi-automation equipment in industrial industries, especially in industries such as robots, special servo equipment, and conventional servo equipment, the volume of existing servo motors with brakes is relatively large, and the motors are easily affected by motor brake dust. And the back-end structure is not convenient for real-time adjustment and maintenance. [0003] Most of the existing motors with brakes are installed with the brakes reversed, and the brakes are fixed on the front end of the rear end cover and placed inside the casing. During the braking process of the brakes, the friction plates will produce powder, which will damage the motor. At the same time, installing the brake inside the casing will also have a certain impact on product assembly, subsequent pro...

And the back-end structure is not convenient for real-time adjustment and maintenance

[0003] Most of the existing motors with brakes are installed with the brakes reversed, and the brakes are fixed on the front end of the rear end cover and placed inside the casing. During the braking process of the brakes, the friction plates will produce powder, which will damage the motor. At the same time, installing the brake inside the casing will also have a certain impact on product assembly and subsequent product disassembly and maintenance.
