Detachable vibration reduction gear

Abstract

The invention discloses a detachable vibration reduction gear, which comprises a basic wheel, wherein the diameter of the basic wheel is not greater than the diameter of a tooth root circle of the gear with a specified basic modulus; axial through slots with the number being the same as the number of gear teeth are formed in the basic wheel; detachable wheel teeth are respectively embedded in the through slots, and comprise tenon bodies inserted in the through slots and tooth heads integrally connected with the tenon bodies; end parts, close to the tenon bodies, of the tooth heads extend to two sides to form tooth head bumps; the lower surfaces of the tooth head bumps are arc faces adapting to the external circular surface of the basic wheel; the upper surfaces of the tooth head bumps are in smooth connection with the tooth profile curved surfaces of the detachable wheel teeth to form part of slot bottom faces of gear tooth slots; wheel tooth fixing slots are formed in gear wheel surfaces; circular ring shaped fixing bars are embedded in the fixing slots; vibration reduction slots are also formed in the tenon bodies of the detachable wheel teeth. The detachable vibration reduction gear provided by the invention not only is simple in structure and convenient for replacing the wheel teeth so as to reduce economic loss, but also can realize the universalization of a gear main body structure and has higher practical value.

Description

technical field

[0001] The invention relates to the technical field of gear transmission, in particular to a detachable damping gear. Background technique

[0002] Gear mechanism is the most widely used transmission mechanism in modern machinery. Gear transmission is an important part of mechanical transmission. It plays the role of transmitting power and motion. With the advantages of mature technology and other advantages, transmission gears are widely used in machine and instrument manufacturing industries. In various heavy-duty institutions, gears are often needed to provide the power required for mechanical operation, and these gears are huge and expensive, and the gears will also suffer some fatal damage during the day and night work, such as: tooth surface wear; tooth surface Pitting, spalling, cracking of the carburized layer on the tooth surface; corrugation on the tooth surface, ribbing on the tooth surface, gluing on the tooth surface, and plastic deformation on ...
