Product introduction

Bear

Bearing housing is a mechanical part used to support and fix bearings, and it plays a key role in various types of mechanical equipment.

Structural features

Main body：

Seat body：The main structure of the bearing seat is usually made of cast iron, cast steel or aluminum alloy, which has enough strength and rigidity to withstand the load transmitted by the bearing and related components. The seat body has various shapes, such as square, round, rectangular, etc., and is designed according to different application scenarios and installation requirements.

Mounting hole：The seat body is provided with holes for installation and fixing, generally including bolt holes and positioning holes. The bolt holes are used to connect the bearing seat with the frame or other support structures of the equipment to ensure the stable installation of the bearing seat. The positioning holes are used to ensure the exact position of the bearing seat during the installation process and improve the installation accuracy.

Bearing installation part：

Bearing cavity：This is the key part used to accommodate the bearing, and its shape and size are designed according to the type and specification of the bearing installed. The inner wall of the bearing cavity is precisely machined to ensure a good fit with the bearing and ensure that the bearing can operate stably in it.

Sealed structure：In order to prevent dust, impurities, moisture, etc. from entering the bearing and affecting the service life and performance of the bearing, the bearing seat is usually equipped with a sealing structure at the bearing installation site. Common sealing methods include rubber seals, labyrinth seals, felt ring seals, etc.

Accessory：

Lubrication channel：In some bearings that require lubrication, a special lubrication channel is provided to transport lubricating oil or grease to the bearing part to reduce friction and wear of the bearing. The design of the lubrication channel should ensure that the lubricating oil can be evenly distributed to all parts of the bearing to improve the lubrication effect.

Heat dissipation structure：For bearings under high-speed operation or high-load working conditions, in order to prevent the bearing from overheating, heat dissipation structures such as heat sinks, heat slots, etc. may be designed to increase the heat dissipation area and improve heat dissipation efficiency.

Working principle

Support and fixed bearings：The bearing housing firmly installs the bearing in a specific position of the equipment through its seat body and mounting hole, providing a stable support platform for the bearing. During the operation of the equipment, the bearing housing bears various loads from the bearing, including radial loads, axial loads and torques, and transmits these loads to the frame or other support structures of the equipment.

Guarantee the accuracy and stability of bearings：The design and manufacturing accuracy of the bearing housing directly affects the working accuracy and stability of the bearing. A high-precision bearing housing can ensure that the installation position of the bearing is accurate, so that the axis of the bearing and the axis of other rotating parts of the equipment maintain good coaxiality, reducing the extra load and vibration caused by installation deviation. At the same time, the stiffness and stability of the bearing housing can also ensure that the bearing will not deform or displace during the working process, thus ensuring the normal operation of the bearing.

Assist in lubrication and sealing of bearings：The lubrication channel and sealing structure of the bearing seat cooperate with the lubrication and sealing system of the bearing to ensure the good working condition of the bearing. The lubrication channel transports lubricating oil or grease to the bearing part, reducing the friction coefficient of the bearing, reducing wear and heat generation; the sealing structure prevents external impurities from entering the bearing and protects the bearing from contamination.

Application field

Industrial machinery：

Machine tool：In all kinds of machine tool equipment, such as lathes, milling machines, grinding machines, etc., the bearing seat is used to support the bearings of key parts such as the main shaft and the feed shaft of the machine tool. Machine tools require high precision and rigidity of the bearing seat to ensure machining accuracy and surface quality.

Fans and pumps：In fan and pump equipment, the bearing housing is used to install the connecting bearing between the motor and the impeller. These devices usually require long-term continuous operation, so the reliability and stability of the bearing housing are required.

Conveyor：In the transmission device of the conveyor, the bearing seat is used to support the bearings of components such as rollers and sprockets. The working environment of the conveyor is usually harsh, and the bearing seat needs to have good dustproof, waterproof and corrosion resistance.

Automotive field：

Engine：The bearings of key components such as crankshafts and camshafts in automobile engines are installed in specially designed bearing housings. Engine bearing housings need to withstand complex working conditions of high temperature, high pressure and high speed operation, and require extremely high strength, heat resistance and wear resistance of materials.

Chassis system：In the suspension system, steering system and transmission system of the automobile chassis, bearing seats are also widely used to install various bearings. These bearing seats need to have good seismic performance and impact resistance to ensure the stability and safety of the car during driving.

Agricultural machinery：

Tractor：The engine, transmission system and farm tool connection parts of the tractor need to use the bearing seat. Agricultural machinery works in a harsh environment and often operates in muddy and bumpy fields, so the bearing seat needs to have good sealing and corrosion resistance.

Harvester：The key parts of the harvester, such as the cutting device, the conveyor device, and the threshing device, are inseparable from the support of the bearing housing. These bearing housings need to be able to adapt to high-speed rotation and frequent start-stop working conditions, and also have a certain degree of self-lubrication performance to reduce the maintenance workload.

Other fields：

Household appliances：In household appliances such as washing machines, air conditioners, refrigerators, etc., the bearings of motors and fans also need to be installed in the bearing housing. Household appliances have high noise and vibration requirements on the bearing housing to provide a quiet and comfortable use environment.

Construction machinery：In cranes, mixers, elevators and other construction machinery, bearing seats are used to support various rotating and transmission components. Construction machinery has high working intensity and strict requirements on bearing capacity and reliability.
