Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a high-speed silent pillow block bearing. Background Technique

[0002] A pillow block bearing, also known as a housing bearing or a pillow block spherical roller bearing, is a bearing unit formed by combining a rolling bearing and a bearing housing;

[0003] For the existing pillow block bearing, during the installation process, its installation is relatively insecure. When the bearing is in use, slight vibrations will occur, and the vibrations may cause the connection and fixation part of the bearing to become loose, affecting subsequent use.

[0004] In order to overcome the above defects, Prior Art 1 (Chinese Patent with Publication No. CN112032196B and Publication Date of June 17, 2022) a pillow block bearing, including a bearing housing, a raised block is arranged at the upper end of the bearing housing, a fixing structure is arranged inside the bearing housing, the fixing structure includes a first fixing hole, a connecting threaded hole, a connecting threaded column, a connecting head and an anti-slip pattern, one side of the fixing structure includes a fixed connecting block, a bearing body is arranged at the upper end of the fixed connecting block, and a first groove is arranged at the front end of the bearing body. Through the action of the fixing structure, the fixing effect of the entire pillow block bearing can be better, avoiding the influence on its use caused by the offset of the pillow block bearing after long-term use, and at the same time, the vibrations generated during the working process of the bearing housing can be greatly reduced, and the damping effect is better. Through the cooperation of the hollow connecting pipe, the first through hole and the second through hole, the connection between the corresponding connecting shaft and the hollow connecting pipe can be relatively firm, and the practical effect is stronger.

[0005] There is also Prior Art 2 (Chinese Patent with Publication No. CN105972100A and Publication Date of September 28, 2016) a pillow block bearing, belonging to the technical field of mechanical equipment. It includes a bearing housing, a positioning mechanism is arranged on the bearing housing, the positioning mechanism includes a slider that can slide on the bearing housing, a convex column installed on the slider and protruding from the bearing housing, and a spring installed inside the slider; a cam mechanism for pushing the slider to move is also arranged on the bearing housing, the cam mechanism includes a rotating plate hinged and installed on the bearing housing, a guiding groove is arranged on the rotating plate, and a guiding protrusion corresponding to the guiding groove is arranged on the slider. When the operator moves the pillow block bearing to a predetermined position, the cam mechanism can be rotated to move the slider out of the bearing housing and insert it into the installation object, thereby enabling quick installation and positioning of the bearing housing.

[0006] Although Prior Art 1 and Prior Art 2 can stably install the pillow block bearing, when the bearing is in use, certain noises will be generated, and the noises may affect the use effect.

[0007] Therefore, we propose a high-speed silent pillow block bearing to facilitate the solution of the above-mentioned problems. Content of the Utility Model

[0008] The purpose of the present utility model is to provide a high-speed silent pillow block bearing to solve the problem that during the use of the bearing as proposed in the above background technology, certain noise will be generated, and the noise may affect the use effect.

[0009] To achieve the above object, the present utility model provides the following technical solution: a high-speed silent pillow block bearing, including a base, and the upper surface at the center of the base is fixedly connected with a bearing body;

[0010] A ball is nested and connected inside the bearing body, and an inner ring is nested and connected at the center of the bearing body. Moreover, an oil supply mechanism for lubricating the ball is arranged between the inside of the inner ring and the bearing body.

[0011] Furthermore, the oil supply mechanism includes lubricating cotton, the lubricating cotton is fixedly connected inside the bearing body, and an elastic arc piece is fixedly connected inside the center of the bearing body. Moreover, an oil storage bag is fixedly connected between the inside of the elastic arc piece and the inner side of the bearing body, and an oil supply pipe penetrates and connects between the oil storage bag and the lubricating cotton.

[0012] Furthermore, the inner side of the lubricating cotton is mutually attached to the outer side of the ball, and the lubricating cotton is arranged in a circular array with respect to the center point of the bearing body.

[0013] Furthermore, the elastic arc piece is arranged in an arc-shaped structure bent inwards, and the elastic arc piece is in contact with the outer side of the inner ring.

[0014] Furthermore, the oil storage bag is mutually communicated with the silent cotton through the oil supply pipe, and two groups of oil supply pipes are arranged on one side of the oil storage bag.

[0015] Furthermore, a silent cotton is nested and connected to the lower surface of the base, and a spring is fixedly connected between the upper surface of the silent cotton and the base.

[0016] Furthermore, the silent cotton is arranged in a rectangular structure, and the silent cotton and the base form an elastic structure through the spring.

[0017] Compared with the prior art, the beneficial effects of the present utility model are:

[0018] 1. A base is arranged below the bearing body, through which the bearing body can be quickly fixed. At the same time, the ball arranged inside the bearing body and the inner ring cooperate with each other, which can further improve the stability of the bearing body during use;

[0019] 2. When the ball rotates, it will be in contact with the lubricating cotton. At this time, the lubricating oil contained in the lubricating cotton can lubricate the outer surface of the ball, further improving the smoothness of the ball's rotation;

[0020] 3. When the inner ring rotates, it will vibrate, and the vibration force will squeeze the elastic arc piece. At this time, the elastic arc piece will undergo elastic deformation under the action of the extrusion force. The elastic arc piece will then squeeze the oil storage bladder, and the lubricating oil inside the oil storage bladder can flow to the lubricating cotton through the oil supply pipe at this time, thus ensuring the lubricating effect of the lubricating cotton on the outer surface of the ball;

[0021] 4. A sound-absorbing cotton is provided on the lower surface of the bearing body. The sound-absorbing cotton can initially block the noise generated by the vibration during the operation of the bearing body. Under the combined action of the sound-absorbing cotton and the lubricating cotton, the sound insulation effect of the bearing body can be further improved;

[0022] 5. Driven by its own elastic force, the spring can make the sound-absorbing cotton better contact with the surface of the installation location, thereby further improving the sound insulation effect. BRIEF DESCRIPTION OF THE DRAWINGS
