High-strength straight gear and manufacturing method thereof

Abstract

The invention discloses a high-strength straight gear and a manufacturing method thereof. The high-strength straight gear comprises a gear ring and a gear hub, wherein the gear hub is arranged in thegear ring and provided with a fixing mechanism, the gear ring is provided with a fixing groove, the fixing mechanism is clamped in the fixing groove, the gear hub is provided with a positioning protruding part, the gear ring is provided with a positioning groove, and the positioning protruding part is arranged in the positioning groove; and the method adopts five steps of a, part manufacturing, b,fixing mechanism assembling, c, gear ring machining, d, gear assembling, and e, gear detection. According to the gear and the method, replacement time of the gear ring can be saved, the gear ring isconvenient to replace, the installation precision of the gear is ensured, slipping between the gear ring and the gear hub is avoided, and the reliability of the gear in the working process is ensured;and by means of the method, gear manufacturing can be facilitated, the gear quality is improved, time needed for gear manufacturing is saved, the production efficiency is improved, and the gear strength is ensured.

Description

technical field [0001] The invention belongs to the technical field of gears, in particular to a high-strength spur gear and a manufacturing method thereof. Background technique [0002] Gears are an important part of mechanical transmissions, which mainly transmit torque and bear loads such as bending and impact. In order to ensure the life and operation stability of the transmission system, the gears must have the following requirements: (1) have a hard surface layer that can resist wear during operation; (2) for gears that are subjected to alternating loads and impact loads , the matrix needs to have sufficient bending strength and toughness to avoid deformation or fracture; (3) It needs to have good manufacturability, it must be easy to cut and have good heat treatment performance. Spur teeth are a kind of classification method of gears. According to the relative position and tooth orientation of a pair of gear axes (whether the two weeks are parallel or not), it can be...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing spur gears have an integral structure, and the teeth need to be replaced as a whole if they are damaged during long-term use, which is not convenient for the overall disassembly and assembly of the gear on the machine, and also increases the cost of replacement and maintenance
