Description

Technical Field

[0001] The utility model relates to the technical field of machinery, and particularly relates to an anti-slip bearing. Background Technique

[0002] In the prior art, a radial rolling bearing generally consists of four parts: an inner ring, an outer ring, rolling elements and a cage. In most cases, its inner ring is fitted with the shaft and rotates together with the shaft; the outer ring is fitted with the bearing housing to play a supporting role; the rolling elements are evenly distributed between the inner ring and the outer ring by means of the cage. The cage can evenly distribute the rolling elements, prevent the rolling elements from falling off, and guide the rolling elements to rotate to play a lubricating role.

[0003] However, when the bearing is installed in parts such as the main engine, the heat generated by the rotation of the bearing and the heat in the bearing housing will cause the bearing outer ring, bearing inner ring and steel balls in the bearing to heat up and expand. At the same time, the bearing housing itself will also expand due to heat. However, due to the different materials of the bearing and the bearing housing, the relative expansion coefficients are also different. When the temperature rises, both the bearing outer ring and the bearing housing will expand radially. And due to the different materials, the size of the radial expansion of the bearing housing is usually larger than the size of the expansion of the bearing outer ring. This results in a large gap between the bearing housing and the bearing outer ring, so that the bearing is prone to creep during operation, thereby affecting the stability of the bearing operation.

[0004] According to the authorized announcement number CN203979153U, an anti-slip bearing is disclosed, which includes a bearing outer ring, a bearing inner ring, rolling elements and a cage. There are several rolling elements and they are arranged between the bearing outer ring and the bearing inner ring; an anti-slip groove is provided on the bearing outer ring, a snap ring is provided in the anti-slip groove, and an anti-slip ring is provided between the bottom wall of the anti-slip groove and the snap ring; anti-slip stripes one are provided on the surface of the snap ring, and anti-slip stripes two are provided on the surface of the anti-slip ring that is in contact with the snap ring. This bearing has a simple structure and good anti-slip effect; the bearing is not prone to creep, which affects the stability of the bearing operation.

[0005] The above patent is provided with a structure for assisting the connection of the bearing, so that the whole bearing will still be unstable during use, resulting in an unstable use state. Therefore, an anti-slip bearing is needed now. Content of the Utility Model

[0006] The purpose of the utility model is to provide an anti-slip bearing, which is used to assist the connection of the bearing body by setting two groups of connecting sleeves to improve the anti-slip performance of the whole device, so as to solve the technical problems mentioned in the background technique.

[0007] To achieve the above object, the present utility model provides the following technical solutions: an anti-slip bearing, comprising a bearing body, wherein an anti-slip groove is provided on the outer surface of the bearing body, and a plurality of groups of inner anti-slip pads are equiangularly embedded and installed on the inner wall of the bearing body;

[0008] Two groups of connecting sleeves are symmetrically bolted and installed on the upper and lower sides of the bearing body. A plurality of groups of deformation grooves are equiangularly provided at the outer ends of each group of connecting sleeves, and an internally threaded pipe is threadedly installed on the outer arc surface of the connecting sleeve.

[0009] Preferably, two groups of connecting grooves are symmetrically provided above and below between adjacent two groups of inner anti-slip pads, and a threaded hole is provided inside each group of connecting grooves.

[0010] Preferably, two groups of limiting baffles are symmetrically and fixedly installed on the outer arc surface of the connecting sleeve, and an external thread is provided on the outer arc surface of the connecting sleeve between the two groups of limiting baffles.

[0011] Preferably, a plurality of groups of arc-shaped insertion plates are equiangularly installed at the bottom of each group of connecting sleeves, and each group of arc-shaped insertion plates is inserted into the corresponding side connecting groove.

A positioning bolt is inserted into each group of receiving through holes, and the end of each group of positioning bolts is threaded into the threaded hole through the receiving through hole.

[0013] Preferably, the central hole of the connecting sleeve is a T-shaped hole, and the opening diameter of the connecting sleeve on the side of the arc-shaped insertion plate is larger. Anti-slip glue points are adhered to the inner wall of the connecting sleeve.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] By providing a plurality of groups of inner anti-slip pads on the inner wall of the bearing body to improve the connection between the bearing body and the external structure, and at the same time, by providing the inner anti-slip pads to improve the anti-slip property between the bearing body and the outside, to reduce the problem of sliding generated during work use.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides: an anti-slip bearing, such as Figures 1 - 5 As shown, it includes a bearing body 1, an anti-skid groove 2 is provided on the outer surface of the bearing body 1, and a plurality of groups of inner anti-skid pads 3 are embedded and installed with equal curvature on the inner wall of the bearing body 1; two groups of connecting sleeves 6 are symmetrically bolted and installed on the upper and lower sides of the bearing body 1, and a plurality of groups of deformation grooves 9 are provided on the outer end of each group of connecting sleeves 6 with equal curvature, and an internal threaded tube 10 is installed on the outer arc surface of the connecting sleeve 6. The anti-skid groove 2 provided on the outer surface of the bearing body 1 can play an anti-skid role when the overall position of the bearing body 1 is fixed, so as to improve the stability when the outer arc surface of the bearing body 1 is used as a fixed surface, and the inner anti-skid pad 3 embedded and installed on the inner wall of the bearing body 1 can play an anti-skid role when the bearing body 1 is connected to an external structure, so as to ensure the stability of the device.

[0024] Preferably, two connecting grooves 4 are symmetrically opened vertically between two adjacent groups of inner anti-slip pads 3. A threaded hole 5 is opened inside each group of connecting grooves 4. Two protective pads 4 opened between two feeding ports 3 are respectively matched with arc-shaped insertion plates 11 on the side edges of connecting sleeves 6 at both ends of the working box 1, so as to limit the connecting sleeves 6, enabling the two connecting sleeves 6 to reinforce the connection relationship of the bearing body 1 from both sides, stably improving the stability of the bearing body 1 during use, reducing the sliding of the bearing body 1 under stress during use, making the overall use of the bearing body 1 safer and more stable. Moreover, since two connecting grooves 4 are opened between every two adjacent groups of inner anti-slip pads 3, the bearing body 1 can choose to install the connecting sleeves 6 unilaterally or synchronously on both sides according to the specific use situation, ensuring the selectivity of the installation and use of the connecting sleeves 6.

[0025] Furthermore, two limiting baffles 7 are symmetrically and fixedly installed on the outer arc surface of the connecting sleeve 6 up and down. An external thread 8 is opened on the outer arc surface of the connecting sleeve 6 between the two limiting baffles 7. The two limiting baffles 7 installed on the outer arc surface of the connecting sleeve 6 limit the internal threaded pipe 10, and the external thread 8 opened on the outer arc surface of the connecting sleeve 6 cooperates with the internal threaded pipe 10 to enable the internal threaded pipe 10 to cooperate with the connecting sleeve 6 to bite tightly the external connecting piece, further improving the connection relationship between the bearing body 1 and the external structure and enhancing the anti-slip property of the bearing body 1.

[0026] Even further, a number of arc-shaped insertion plates 11 are installed at equal arcs at the bottom of each group of connecting sleeves 6. Each group of arc-shaped insertion plates 11 is inserted into the corresponding connecting groove 4. At the center of the inner arc surface of each group of arc-shaped insertion plates 11, a storage through hole 12 is opened corresponding to the position of the threaded hole 5. A positioning bolt 13 is inserted into each group of storage through holes 12. The end of each group of positioning bolts 13 is screwed into the threaded hole 5 through the storage through hole 12 for threaded connection. After the arc-shaped insertion plate 11 at the bottom of the connecting sleeve 6 fits against the inner wall of the connecting groove 4, the connection with the inner wall of the bearing body 1 is completed through the set positioning bolt 13, which can ensure the overall use stability of the connecting sleeve 6 after the arc-shaped insertion plate 11 is fixed. Thus, the overall contact area between the bearing body 1 and the external structure is extended through the connecting sleeve 6, and the anti-slip property of the overall bearing body 1 is further improved in cooperation with the inner anti-slip pads 3 embedded in the inner wall of the bearing body 1. The opened storage through hole 12 can ensure that the positioning bolt 13 is stored inside the storage through hole 12, avoiding the protruding positioning bolt 13 from affecting the external connecting piece. At the same time, after the external connecting piece is inserted and matched with the bearing body 1, the external connecting piece can limit the positioning bolt 13, preventing the positioning bolt 13 from detaching from the storage through hole 12 and further enhancing the connectivity of the connecting sleeve 6.

[0027] Specifically, the central hole of the connecting sleeve 6 is a T-shaped hole, and the opening diameter of the connecting sleeve 6 on one side of the arc-shaped plug plate 11 is larger. Anti-slip glue dots are adhered to the inner wall of the connecting sleeve 6, and the opening diameter of the outer end of the connecting sleeve 6 is smaller. When the external connector is inserted, the opening end of the connecting sleeve 6 will be propped up, and the deformation groove 9 opened at the outer end of the connecting sleeve 6 can enable the connecting sleeve 6 to flexibly change its shape, and the reset of the connecting sleeve 6 is ensured by rotating the internal thread tube 10, further improving the locking property of the connecting sleeve 6 to the external connector.

[0028] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
