Low-noise worm gear and worm reduction gearbox

Abstract

The invention discloses a low-noise worm gear and worm reduction gearbox. The low-noise worm gear and worm reduction gearbox is characterized by comprising a box body, a worm gear, a worm and a transmission shaft, wherein the worm gear, the worm and the transmission shaft are arranged in the box body, the worm drives the worm gear to move, and then the transmission shaft is driven to rotate; and the worm gear comprises a tooth surface and a center part, wherein the tooth surface is fixedly connected with the center part, the tooth surface is made of plastic, and the center part is made of metal. On the basis of a traditional reduction gearbox, the plastic tooth surface is combined with the metal center part, and the arc-shaped toothed edge is arranged on the tooth surface, so that the abrasion is reduced while the high-torque high-strength output is guaranteed, the service life is prolonged, moreover, the noise is reduced, and then the product quality is improved.

Description

technical field [0001] The invention relates to the field of reduction boxes, in particular to a low-noise worm gear reduction box. Background technique [0002] The gearbox is an essential part of the motor transmission, which plays the role of deceleration and torque increase. The worm gearbox can change the transmission direction of the motor shaft and reduce the axial size of the output end. However, due to the characteristics of frictional transmission between worm gears and worms, traditional metal worm gear gearboxes tend to generate relatively large noise during the transmission process; in addition, long-term friction will also affect the service life and transmission accuracy of worm gears ; Due to the low plasticity and toughness of plastic materials, the worm gear gearbox made of plastic materials cannot meet the corresponding root bending strength requirements, and the connection between the worm gear and the output shaft is easy to slip, which cannot meet the r...
