Small width regulation device

Abstract

A small width adjustment device, including a driving screw, a driven screw and a transmission mechanism, the transmission mechanism includes a transmission rod and a bevel gear, a bevel gear is installed at both ends of the transmission rod, and one of the bevel gears is connected to the bevel gear installed at the front end of the driving screw. The other bevel gear meshes with the bevel gear installed on the front end of the driven screw, and the torx nut is installed on the rear end of the driving screw; the driving screw, driven screw and transmission mechanism are all located at the bottom of the device body, and the top of the device body is equipped with Two width-adjusting plates arranged in parallel, the two ends of the width-adjusting plate on the front side are respectively connected with left-handed nuts, and the two left-handed nuts are threadedly connected with the driving screw and the driven screw respectively, and the two ends of the width-adjusting plate on the rear side are respectively Connect the right-handed nut; the small width adjustment device is simple in structure and ingenious in design. It achieves specific effects through two pairs of small bevel gears and thread transmission. It is low in cost, practical in a small space, compact and beautiful, and worthy of vigorous promotion.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a small width adjusting device. Background technique [0002] The existing width adjusting device basically uses a worm gear and a synchronous belt to adjust the width, and the worm drive is a transmission that transmits motion and power between two axes that are interlaced in space. Worm drives are used to transmit motion and power between staggered shafts. The transmission efficiency is low and the wear is serious. When the worm gear meshes and drives, the relative sliding speed between the meshing gear teeth is large, so the friction loss is large and the efficiency is low. On the other hand, the relative sliding speed causes severe wear and heat on the tooth surface. In order to dissipate heat and reduce wear, more expensive materials with better anti-friction and anti-wear properties and good lubrication devices are often used, so the cost is higher. . The worm gear t...

When the worm gear meshes and drives, the relative sliding speed between the meshing gear teeth is large, so the friction loss is large and the efficiency is low

On the other hand, the relative sliding speed causes severe wear and heat on the tooth surface. In order to dissipate heat and reduce wear, more expensive materials with better anti-friction and anti-wear properties and good lubrication devices are often used, so the cost is higher.

The worm gear takes up a lot of space, and it is not beautiful enough, and the timing belt needs to be tightened to adjust the width, which is not practical in a small space.
