High-temperature-resistance bearing bush with heat dissipation easy to carry out

Abstract

The invention provides a high-temperature-resistance bearing bush with heat dissipation easy to carry out. The high-temperature-resistance bearing bush with heat dissipation easy to carry out comprises a left bearing bush ring, fasteners, embedment guide grooves and a right bearing bush. Each fastener and the corresponding embedment guide groove are in mutual nesting. The left bearing bush ring and the right bearing bush ring abut against each other. The left bearing bush ring and the right bearing bush ring are fixedly connected through the fasteners. An oil storage tank is integrally inlaidin the inner side of the left bearing bush ring. An oil delivery port is integrally arranged at the top end of the interior of the oil storage tank. Four oil delivery ports communicate with the rightside of the interior of the oil storage tank. Four oil limiting screens are fixedly arranged on the inner sides of the four oil delivery ports respectively. According to the high-temperature-resistance bearing bush with heat dissipation easy to carry out, a left air passage and a right air passage are arranged, and because of the left air passage and the right air passage are symmetrical to each other, both the interior of the left bearing bush ring and the interior of the right bearing bush ring have a certain function of ventilation with the air in the outside world for heat dissipation; andfurthermore, because the left air passage and the right air passage are each arranged in a Z-shaped structure, the interior of the left bearing bush ring and the interior of the right bearing bush ring form the process of internal circulation of heat dissipation air respectively, and a good heat dissipation effect is achieved.

Description

technical field [0001] The invention relates to the technical field of bearing pads, in particular to a bearing pad. Background technique [0002] The bearing shell is the contact part of the sliding bearing and the journal. The shape is a tile-like semi-cylindrical surface, which is very smooth. It is generally made of wear-resistant materials such as bronze and anti-friction alloy. In special cases, it can be made of wood, engineering Made of plastic or rubber, there are two types of bearings: integral and split. The integral bearing is usually called bushing. The integral bearing has two types: oil groove or oil groove. The bearing and journal adopt clearance fit. , generally does not rotate with the axis. [0003] The existing bearing pads are weak in heat dissipation, and the friction between the bearing pad and the bearing for a long time, even if the friction coefficient is small, it is still easy to heat up after long-term work, resulting in the rapid wear of the in...

Problems solved by technology

[0004] The purpose of the present invention is to solve the technical problem that the lubricating oil film is quickly worn away, so that the service life of the bearing bush is short, the lubricating oil is not easy to volatilize inside, and the lubricating oil film cannot be evenly applied to the inner wall of the inner wall, and to provide a heat-resistant bearing High-temperature bearing pad, the high-temperature resistant bearing pad that is easy to dissipate heat is provided with a left ventilation slot and a right ventilation slot. Through two mutually symmetrical left ventilation slots and right ventilation slots, the inside of the left bearing pad ring and the right bearing pad ring have a certain degree of air contact with the outside world. The function of ventilation and heat dissipation, and the setting of the left ventilation slot and the right ventilation slot in a Z-shaped structure allows the internal circulation of heat dissipation air to be formed inside the left bearing ring and the right bearing ring, which has a good heat dissipation effect and solves the problem of rapid wear of the lubricating oil film in the past. The service life of the bearing bush is short, the lubricating oil is not easy to volatilize inside, and it cannot be evenly applied to form a lubricating oil film on the inner wall
