This can cause the shaft hole and the oil filling hole to deform during use under the pressure of the shaft. This can cause the air conditioner impeller to shake and make unusual noises during operation, seriously shortening its service life. Utility Model Content

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A wind wheel resin bearing comprises: a bearing body, an axial hole opened in the center of the bearing body, three oil injection holes arranged around the axial hole, and a support body arranged between the three oil injection holes and the axial hole; the three oil injection holes are distributed in an array according to the center of the axial hole.

[0007] Preferably, the support body includes a main support member and a reinforcement member installed on the main support member; the oblique side of the reinforcement member forms an angle θ with the horizontal side of the main support member.

[0008] Preferably, the angle θ is 15-30°.

[0009] Compared with the prior art, this application has the following beneficial effects:

[0010] The utility model adopts a support body, which can effectively bear the weight of the shaft during the use of the wind wheel resin bearing, prevent the shaft hole and the oil filling hole from deformation, thereby effectively preventing the bearing from shaking and causing noise, and improving the service life of the wind wheel resin bearing. Specifically, a reinforcement member is installed on the original main support member to improve the strength of the main support member, thereby improving the pressure bearing capacity of the support body.

[0017] The following describes some embodiments of the present invention in detail with reference to the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.

[0018] Example 1:

[0019] A wind wheel resin bearing comprises: a bearing body 10, an axial hole 20 provided in the center of the bearing body 10, three oil injection holes 30 arranged around the axial hole 20, and a support body 40 arranged between the three oil injection holes 30 and the axial hole 20; the three oil injection holes 30 are distributed in an array according to the center of the axial hole 20; the support body 40 comprises a main support member 41 and a reinforcement member 42 mounted on the main support member 41; the oblique side of the reinforcement member 42 forms an angle θ with the horizontal side of the main support member 41; the angle θ is 15-30°.

[0020] like Figure 1 and Figure 2 As shown, the wind wheel resin bearing is inserted into the external shaft through the shaft hole 20 for use. During use, the oil in the three oil holes 30 continuously provides lubrication between the bearing and the shaft. When the grease in the oil hole 30 continues to decrease, the shaft will produce a certain pressure on the bearing. At this time, the support body 40 arranged between the shaft hole 20 and the oil hole 30 will receive pressure from the shaft. If the support body 40 is not strong enough, it will be deformed, causing the shaft hole 20 and the oil hole 30 to deform in size, thereby causing the bearing to shake and produce abnormal noise during use.

[0021] In order to solve the above problems, the supporting strength of the support body 40 is improved. Furthermore, the support body 40 is provided with a main support member 41 and a reinforcement member 42, thereby increasing the thickness of the original support body 40 and strengthening the pressure-bearing capacity of the support body 40, thereby preventing the shaft hole 20 and the oil filling hole 30 from being deformed during use, solving the problem of shaking and abnormal noise generated by the bearing during use, and improving the service life of the bearing.

[0022] In order to further improve the stability of the support body 40, the reinforcement member 42 is set to a triangular structure, and the oblique side of the reinforcement member 42 forms an angle θ with the horizontal side of the main support member 41; the angle θ is 15-30 degrees.

[0023] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, from all perspectives, the embodiments should be regarded as illustrative and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes that fall within the meaning and range of equivalents of the claims be included in the present invention. Any reference signs in the claims should not be construed as limiting the claim to which they relate.
