Description

Technical Field

[0001] The utility model relates to the technical field of motor bearings, in particular to a bearing structure for high-speed motors. Background Art

[0002] During the use of the high-speed motor bearing structure, in order to improve the lubricity of the bearing, the bearing is generally emulsified regularly. In the prior art, according to the authorization announcement number CN 217814577U, a lubrication structure for the bearing of a high-speed motor is disclosed. A lubrication mechanism is provided, and the lubrication mechanism is installed in the motor housing and connected with the oil filling pipe on the motor housing. A plurality of branch oil holes are set on the outer shaft by the lubrication mechanism, so that oil gas or oil mist enters the outer shaft from the oil filling pipe, and then is sprayed by the plurality of branch oil holes, so as to achieve lubrication of each rolling element, effectively enhance the lubrication effect of the bearing, and improve the durability and flexibility of the bearing. However, during the use of the above technical solution, when oiling, due to the relatively slow flow rate of the lubricating oil, the lubricating oil is easy to overflow during pressurized oiling, resulting in oil stains around the oil filling pipe, which not only causes waste of lubricating oil, but also absorbs more dust at the oil stain position in the long run. Utility Model Content

[0003] Therefore, the purpose of the utility model is to provide a bearing structure for high-speed motors. Through the mutual cooperation of the bearing assembly and the oil filling anti-overflow assembly, an extended oil storage bin is formed at the position of the oil filling pipe when in use. In this way, when the lubricating oil overflows, it is directly collected by the vertically distributed oil storage bin to avoid the overflow of the lubricating oil. In addition, during the oil filling process, the stepped docking position is directly applicable to oil filling structures with different pipe diameters, and has high applicability.

[0004] In order to solve the above technical problems, according to one aspect of the present invention, the present invention provides the following technical solution: a bearing structure for a high-speed motor, comprising:

[0005] A bearing assembly, the bearing assembly comprising a motor housing frame, a bearing body arranged in the motor housing frame, and an oil injection pipe connected to the bearing body;

[0006] The oil filling anti-overflow component includes a connecting sleeve connected to the oil filling pipe, a step groove opened in the connecting sleeve, a plastic liquid storage shell arranged on the outside of the oil filling pipe, a first folding liquid storage tank connected to the plastic liquid storage tank, a second folding liquid storage tank and a third folding liquid storage tank.

[0007] As a preferred solution of the bearing structure for a high-speed motor described in the utility model, the first folding liquid storage bin, the second folding liquid storage bin and the third folding liquid storage bin have equal structures, and the first folding liquid storage bin, the second folding liquid storage bin and the third folding liquid storage bin are squeezed and folded under force.

[0008] As a preferred solution of a bearing structure for a high-speed motor described in the utility model, it also includes a limit assembly, which includes an L-shaped plate fixed to the top of the motor housing frame, a threaded column fixed to the top of the L-shaped plate, and a pressure plate arranged above the threaded column.

[0009] As a preferred solution of the bearing structure for a high-speed motor described in the utility model, the limit assembly further includes a threaded hole opened on the surface of the pressure plate;

[0010] The threaded hole and the threaded column are connected to each other, and the pressing plate is pressed on the top surface of the plastic liquid storage shell.

[0011] As a preferred solution of the bearing structure for a high-speed motor described in the utility model, it also includes a flow guide component, which includes a flow guide pipe connected to the third folding liquid storage tank and a rubber plug arranged in the flow guide pipe.

[0012] As a preferred solution of the bearing structure for a high-speed motor described in the utility model, there are a plurality of step grooves, and the diameter of each step groove decreases from top to bottom.

[0013] Compared with the prior art, the advantages of the utility model are:

[0014] 1. The utility model forms an extended oil storage bin at the position of the oil filling pipe through the cooperation of the bearing assembly and the oil filling anti-overflow assembly when in use. In this way, when the lubricating oil overflows, it is directly collected by the vertically distributed oil storage bin to avoid the lubricating oil overflow. In addition, during the oil filling process, the stepped docking position is directly applicable to the oil filling structure of different pipe diameters, and has high applicability.

[0015] 2. Based on the first beneficial effect, the limit component is set to compress and limit the used oil filling anti-overflow component to avoid the situation where the lubricating oil drips and overflows due to the left and right swinging caused by the vibration of the motor when not in use.

[0016] During specific use, lubricating oil is injected through the oil filling pipe. During the oil filling process, the oil filling head is directly fitted with the connecting sleeve to carry out oil filling. Since a number of step grooves are arranged in the connecting sleeve, the step grooves are directly suitable for docking with oil filling heads of different pipe diameters. During the oil filling process of the oil filling head, when the oil pressure is high and the lubricating oil overflows, the plastic liquid storage shell stores the overflowed lubricating oil. At this time, the first folding liquid storage tank, the second folding liquid storage tank and the third folding liquid storage tank expand the liquid storage capacity of the plastic liquid storage shell to further avoid lubricating oil overflow.
