Abstract

The invention discloses a belt wheel tensioning and fast-changing device which comprises a machine frame; a machine is arranged at the top of the machine frame; guide rails are arranged on the two sides of the lower part of the machine frame; a motor support is arranged on the guide rails in a spanning manner and can move along the guide rails; a motor is fixedly arranged on the motor support and is connected with the machine through a belt; a lead screw is arranged under the motor support; a motor support nut is arranged on the surface of the bottom of the motor support; the lead screw penetrates through the motor support nut and realizes the effect that the lead screw drives the motor support to move in a threaded connection way; the two ends of the lead screw are placed on the machine frame; a bearing is arranged at the connecting part of the lead screw and the machine frame. The belt wheel tensioning and fast-changing device is simple in structure and convenient to operate, has a good self-locking function, can easily realize the tensioning of the belt and can also realize the fast change of the belt among different machines; meanwhile, the device can be directly mounted on an existing machine, thereby being economic and practical.

Description

technical field [0001] The invention relates to the technical field of belt tensioning and rapid replacement in belt transmission, in particular to a pulley tensioning and rapid replacement device. Background technique [0002] Belt drive is the most commonly used transmission device in mechanical equipment. However, due to the long-term operation of the belt, plastic deformation and wear will occur, which reduces the tension of the belt and loses the transmission effect. At present, there are many belt tensioning devices, most of which are realized by adding a pinch wheel, which will cause friction between the pinch wheel and the belt, which will reduce the life of the belt; Such devices do not improve the ease of belt replacement. There are some devices that change the tension of the belt by changing the center distance, but the convenience of belt replacement is generally not considered, and most of them are for a single machine. In view of this, it is necessary to desi...
