Improved hard tooth surface worm-gear speed reducer

Abstract

The invention relates to an improved worm-gear speed reducer with a hard tooth surface, belongs to the technical field of precision machining equipment, and aims to provide an improved worm-gear speed reducer with a hard tooth surface, which can adjust axial clearance and radial clearance, is economical and practical, and has high repeated positioning accuracy. The invention adopts the technical key that the worm-gear speed reducer comprises a worm fixed on a worm bearing support through a bearing, and a worm gear fixed on a worm gear bearing support through a bearing, wherein the worm is meshed with the worm gear, the connection surfaces of the worm bearing support and the worm gear bearing support are in mutual matched installation of an arc surface and a plane, and an annular sealing ring is arranged between the two contact surfaces and fixedly connected with a bolt through a positioning pin. The worm-gear speed reducer has the advantages of compact, advanced, reasonable and scientific structure, and wide application range, and is suitable for manipulators, high-precision rotary workbenchs and the like used with high-precision equipment such as a servomotor and the like in particular.

Description

Technical field [0001] The invention relates to an improved hard-tooth surface worm reducer, which belongs to the technical field of reduction machinery. Background technique [0002] Worm gear reducer is an important deceleration equipment in mechanical transmission. Because of its self-locking ability and high transmission ratio, it is widely used in metallurgy, mining, heavy machinery transportation, petrochemical industry, building materials, light industry, etc. Industries have a wide range of applications. However, the traditional worm gear reducer can only adjust the axial clearance, and the center distance between the worm wheel and the worm is fixed. Due to the inevitable errors in the process of design, processing and assembly, the radial clearance between the worm gear and the worm always exists, so the axial clearance can only be adjusted on one side, and the side clearance on the other side is larger. Its use is limited in occasions where rotation and repeated...

Problems solved by technology

However, the traditional worm gear reducer can only adjust the axial clearance, and the center distance between the worm wheel and the worm is fixed.

Due to the inevitable errors in the process of design, processing and assembly, the radial clearance between the worm gear and the worm always exists, so the axial clearance can only be adjusted on one side, and the side clearance on the other side is larger. Its use is limited in occasions where high requirements for rotation and repeated positioning are required.
