A Method of Prolonging the Service Life of Lathe

Abstract

The invention belongs to the technical field of lathes and particularly relates to a method for prolonging the service life of a lathe. According to the method, a soft start coupling is used. The coupling comprises an output shaft and a driving shaft. One end of the output shaft is used for being connected with a motor shaft, and the other end of the output shaft is provided with the driving shaft. The driving shaft is used for being connected with working equipment. A set of mounting blocks are arranged at the outer circle of the output shaft. The end of the driving shaft is provided with a cavity. A set of clamping grooves are uniformly formed in the inner wall of the cavity and used for being matched with guiding rods to be used. Each guiding rod is mounted on the corresponding mountingblock in a sliding manner. The bottom of each guiding rod is connected to the corresponding mounting block through a spring. When the motor shaft rotates, the guiding rods on the mounting blocks slide toward the outer side of the output shaft under the effect of centrifugal force, so that the output shaft and the driving shaft are linked gradually from the separated state; buffer can be achievedwhen a motor starts; the start torque of the motor is reduced; and soft start of the motor is achieved.

Description

technical field [0001] The invention belongs to the technical field of lathes, in particular to a method for prolonging the service life of lathes. Background technique [0002] With the rapid development of technology, lathes have rapidly become popular in the manufacturing industry. When a common lathe is started, the motor shaft rotates to drive the driven shaft, and the motor shaft is fixedly connected to the driven shaft. However, when the motor is started frequently, the motor needs a large torque to drive the driven shaft; in this state, the motor of the lathe is damaged greatly, and the service life of the lathe is reduced. In order to change this defect, the present invention connects the motor shaft and the driven shaft with a soft start coupling to realize the soft start of the motor and prolong the service life of the lathe. [0003] Couplings are also called couplings. A mechanical component used to firmly couple the driving shaft and the driven shaft in diff...

AI Technical Summary

Problems solved by technology

[0004] The commonly used coupling can realize the linkage between the driving shaft and the driven shaft; but when the motor is started with load, using the commonly used coupling, the motor will generate a large torque when starting, or even fail to start, and it will also cause damage to the motor. Damage, reducing the service life of the lathe motor
