Embodiment 1

[0028] The detachable durable gear includes a gear body 1 and a plurality of gear teeth 2 evenly distributed on the outer circumference of the gear body 1. The lower end of the gear teeth 2 is provided with a slot 3, and the gear teeth 2 are stuck in the gear body 1 through the slot 3. On the outer circular side wall, the gear body 1 and the gear teeth 2 are connected by bolts; the outer circumference of the gear body 1 is uniformly provided with a plurality of positioning protrusions 4, the gear teeth 2 are located between the adjacent positioning protrusions 4, and the positioning protrusions 4 The height is less than the height of the gear teeth 2; the inside of the gear body 1 is provided with an annular chamber 5 and several oil guide pipes 6 communicating with the annular chamber 5, and an oil outlet hole communicating with the oil guide pipe 6 is opened on the positioning protrusion 4 7.

Embodiment 2

[0030] In this embodiment, on the basis of Embodiment 1, there are several threaded holes A8 evenly distributed on the outer peripheral edge of the gear body 1 for installing the gear teeth 2, and the two sides of the slot 3 of the gear teeth 2 are respectively provided with Threaded hole B9 matched with threaded hole A8.

Embodiment 3

[0032] In this embodiment, on the basis of embodiment 1 or embodiment 2, the gear body 1 is provided with a plurality of weight reducing holes 10 , and the plurality of weight reducing holes 10 are evenly distributed on the gear body 1 .

Abstract

The invention discloses a detachable durable gear. The detachable durable gear comprises a gear body and a plurality of gear teeth which are uniformly distributed on the periphery of the gear body; clamping grooves are formed in the lower ends of the gear teeth; the gear teeth are clamped on the side wall of the outer circle of the gear body through the clamping grooves; the gear body is connected with the lower ends of the gear teeth through bolts; a plurality of positioning bumps are uniformly formed in the periphery of the gear body; each gear tooth is positioned between adjacent positioning bumps; the height of the positioning bumps is smaller than that of the gear teeth; an annular cavity is formed in the gear body, and a plurality of oil guide pipes which are communicated with the annular cavity are arranged in the gear body; oil outlet holes which are communicated with the oil guide pipes are formed in the positioning bumps. According to the detachable durable gear, the lower ends of the gear teeth are clamped on the side wall of the outer circle of the gear body through the clamping grooves and are connected with the gear body through the bolts, so that the gear teeth are easy to detach; when a gear tooth is damaged, only the corresponding damaged gear tooth is required to be replaced without replacing the overall gear, so that the production cost is greatly reduced, and the fault maintenance time is greatly shortened.

Description

technical field [0001] The present invention relates to a gear, and more particularly to a detachable durable 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, plastic deformation on the tooth surface. It...
