Description

Technical Field

[0001] The utility model relates to a resin bearing, in particular to a high-load silent resin bearing, belonging to the technical field of the air wheel component of an air conditioner Background Art

[0002] In various household appliance brand air conditioners and automotive air conditioners, the inner air wheel component is widely used, and the inner air wheel resin bearing is the most core component in the inner air wheel component. At present, the bearing hole of the commonly used inner air wheel resin bearing is too small; the outer side of the middle part of the bearing bulges outwards in a circular shape, and the circular shape is easy to be driven, causing the bearing to be misaligned and affecting the use effect Content of the Utility Model

[0003] The purpose of the utility model is to provide a high-load silent resin bearing aiming at the defects of small bearing holes and easy bearing misalignment in the prior art of the inner air wheel resin bearing of various household appliance brand air conditioners and automotive air conditioners, which can achieve the purpose of installing a large bearing and no bearing misalignment

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is: a high-load silent resin bearing, including a bearing body, the center of the bearing body is a circular bearing hole, and 3 oil storage blind holes are uniformly arranged in the bearing body. The oil storage blind holes are in a flat shape as a whole, and an oil groove is arranged between the middle part of the inner side of the oil storage blind hole and the circular bearing hole

[0005] The upper part of the oil storage blind hole is an opening part, and a circular groove is arranged above the opening part and on the upper part of the bearing body. The diameter of the circular groove is larger than the diameter of the bearing hole, and a cover plate is arranged in the circular groove. The periphery of the cover plate and the inner edge of the circular groove are in a tight fit. The cover plate includes a cover plate hole, and the cover plate hole is in the middle of the cover plate. The diameter of the cover plate hole is equal to the diameter of the bearing hole

[0006] The outer side of the middle part of the bearing body bulges outwards, and the convex surface is a plane

[0007] The opening diameter of the circular bearing hole is greater than 7mm

[0008] The outer side edge of the oil storage blind hole is arc-shaped and the inner side edge is plane-shaped

[0009] The cover plate and the circular groove on the upper part of the bearing body are in a pressing connection; the bearing body is made of POM polyformaldehyde resin material and is integrally injection-molded by an injection molding machine

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows: To solve the problems of the existing products, such as the resin bearing being prone to rotate inside the bearing seat after assembly due to the round shape at both ends, the resin bearing falling out of the bearing seat during the bumpy transportation of the whole machine, and the fan blade being pushed askew by the small shaft during the installation of the fan blade on the production line, etc. Through design improvement, both ends of the product sphere are made into a platform shape, so that the product can be effectively fixed in the product after installation. The design of the platform also avoids the rotation of the original product inside the bearing seat due to the overall round shape, enabling the product to maintain the installation state without random sliding; the inner hole of the product is enlarged to cooperate with the use of a large steel shaft, which is more stable than the original product, and the vibration is also greatly reduced.

[0015] The present utility model will be further described below with reference to the accompanying drawings and specific embodiments, but it is not intended to limit the present utility model.

[0016] As Figures 1 to 3 shown, a high-load and silent resin bearing includes a bearing body 1, the center of the bearing body 1 is a circular bearing hole 2, and 3 oil storage blind holes 3 are evenly arranged in the bearing body 1. The oil storage blind holes 3 are overall flat, and an oil groove is arranged between the middle part of the inner side of the oil storage blind hole 3 and the circular bearing hole 2;

[0017] The upper part of the oil storage blind hole 3 is an opening part, and a circular groove 4 is arranged above the opening part and on the upper part of the bearing body. The diameter of the circular groove 4 is larger than the diameter of the bearing hole. A cover plate 5 is arranged in the circular groove. The periphery of the cover plate 5 is in a tight fit with the inner edge of the circular groove 4. The cover plate 5 includes a cover plate hole, and the cover plate hole is in the middle of the cover plate. The diameter of the cover plate hole is equal to the diameter of the bearing hole;

[0018] The outer side of the middle part of the bearing body 1 bulges outwards, and the protruding surface is a plane 6.

[0019] The opening diameter φ of the circular bearing hole is greater than 7 mm.

[0020] The outer side of the oil storage blind hole 3 is arc-shaped and the inner side is flat-shaped.

[0021] The cover plate and the circular groove on the upper part of the bearing body are tightly connected; the bearing body is made of POM polyformaldehyde resin material and is integrally injection-molded by an injection molding machine.

[0022] The above embodiments are only one of the more preferred specific embodiments of the present invention. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included in the protection scope of the present invention.
