Abstract

The invention relates to a vibration reduction and noise elimination nut device and a linear motion system adopting the device. The vibration reduction and noise elimination nut device comprises a guide rail sliding block, a nut connecting piece, a linear guide rail, a mechanism, a screw rod and a motor. One end of a nut is connected with the guide rail sliding block and the mechanism through thenut connecting piece, the other end of the nut is connected with the motor through the screw rod, and the guide rail sliding block is connected with the linear guide rail. The system further comprisesthe vibration reduction and noise elimination nut device, the device comprises the nut and a vibration reduction and noise elimination module, and the vibration reduction and noise elimination moduleis installed on the nut and used for blocking a vibration path and eliminating noise. Compared with the prior art, vibration of a linear motion system with a screw rod and a stepping motor or a brushless servo motor is greatly reduced, and therefore noise generated by the system during operation is reduced at the same time.

Description

technical field [0001] The invention relates to a linear motion system, in particular to a vibration and noise reduction nut device and a linear motion system using the device. Background technique [0002] For the growing automation and robot industry applications, the transmission system with trapezoidal screw or ball screw can convert rotary motion into linear motion, so as to realize the transmission mechanism form of position to position or multi-axis linear motion. In this type of linear motion system, trapezoidal nuts or ball nuts are usually used to cooperate with corresponding screw rods to convert the rotational torque generated by the motor into linear motion. Since the linear system includes motors such as servo motors, brushless motors or stepper motors, these motors will vibrate during certain movements due to their structural characteristics and electrical parameters, and this vibration will also be introduced into the linear motion system. , and because the ...
