Detailed Description

It is easily understood that, according to the technical solution of the present invention, under the spirit of the present invention, a person skilled in the art can propose various alternative structural modes and implementation modes. Therefore, the following detailed description and the accompanying drawings are only exemplary of the technical aspects of the present invention, and should not be considered as limiting or restricting the technical aspects of the present invention in its entirety or as limiting or restricting the technical aspects of the present invention.

An embodiment according to the present invention is shown in connection with fig. 1. Integral type bearing, including bearing inner race 1, bearing inner race 2, sealed 3, installation department 4, ball 5, be provided with ball 5 between bearing inner race 1 and the bearing inner race 2 and rotate to connect in bearing inner race 1 in order to be used for bearing inner race 2, be provided with sealed 3 operation of filling up in order to be used for preventing external impurity influence ball 5 between bearing inner race 1 and the bearing inner race 2, bearing inner race 1 is close to the outer wall of its one side and is provided with installation department 4. Because the production and processing modes of the bearing and the bearing protection seat are different, the dimensional accuracy of the two parts is different; during pressing, due to the fact that the position and the pressing force are different during pressing caused by the size difference of two parts and the size difference of parts, the coaxiality consistency of a pressed bearing and a bearing protection seat is poor, and the gap change of a bearing clearance bearing ball, an inner ring and an outer ring is large due to the pressing force. The installation of bearing needs outside article to pound hit or the instrument is pressed into, and this process can not avoid the problem, and to different scenes, some interference fit's channel is too big or undersize, all is difficult to install the bearing. Break through current thinking, at this installation department 4 of one side installation of bearing inner race 1, this bearing is installed to installation department 4 to reduce and exempt from current hitting, the instrument installation, and diminish to the channel of installation or other auxiliary mounting spare demands, the suitability is wider relatively, has had higher promotion for prior art.

Specifically, as shown in fig. 4 and 5, a plurality of protection plates 11 are arranged on one side of the bearing outer ring 1 close to the mounting portion 4, the protection plates 11 form a complete ring for protecting the device, and each protection plate 11 and the bearing outer ring 1 are provided with an elastic buffer device;

elastic buffer includes holding down plate 17, holding down plate 17 is installed in one side that protection shield 11 is close to bearing inner race 1, holding down plate 17 is kept away from fixedly connected with second elastic component 16 between one side of protection shield 11 and the bearing inner race 1, the spacing sliding connection in 1 one side of bearing inner race has two to slide and divides clamp plate 14, the both sides of holding down plate 17 articulate with two slide branch clamp plates 14 respectively and have articulated strip 15, one side that two slide branch clamp plates 14 kept away from each other is provided with fixed plate 12, two fixed plates 12 divide clamp plate 14 fixed connection first elastic component 13 with two slides respectively, fixed plate 12 fixed mounting is on bearing inner race 1. After the bearing is installed, the installation part 4 may be hit by a foreign object, and the installation effect of the bearing may be affected. To this end, anti-pounding devices have been designed to divide the force of the pounding. When a foreign object smashes one of the protection plates 11 or a plurality of protection plates 11, the protection plate 11 drives the lower pressing plate 17 to move downwards, the lower pressing plate 17 buffers the smashing force through the second elastic piece 16, the lower pressing plate 17 moving downwards enables the two sliding sub pressing plates 14 to move towards two sides through the two hinge strips 15, the sliding sub pressing plates 14 moving towards two sides buffer the smashing force through the first elastic pieces 13, the force direction is 90 degrees, and therefore the influence caused by the smashing force is greatly reduced.

Specifically, as shown in fig. 2 and 3, a plurality of round pits 6 are formed in the middle of the inner wall of the bearing outer ring 1, the balls 5 are rotatably connected in the round pits 6, and the round pits 6 are uniformly distributed on the bearing outer ring 1. The provision of the circular pits 6 allows a stable circumferential rotation of the rollers 5 and thus a stable rotation of the bearing inner ring 2.

Specifically, as shown in fig. 2 and 3, two auxiliary plates 7 are fixedly connected to the inner wall of the bearing outer ring 1, the two auxiliary plates 7 are located on the left and right sides of the balls 5, cambered surfaces 8 matched with the balls 5 are respectively formed on one sides of the two auxiliary plates 7 close to the balls 5, and the auxiliary plates 7 are separated from the bearing inner ring 2. So that the rollers 5 do not roll out of the pockets 6 when subjected to external forces, making the device more stable.

Specifically, as shown in fig. 2 and 3, the left side and the right side of the outer wall of the bearing inner ring 2 are both provided with a slideway 9, the auxiliary plate 7 is fixedly connected with an extension block 10, and the extension block 10 is arranged in the slideway 9. So that the bearing inner race 2 can be stably seated in the device.

Specifically, as shown in fig. 2 and 3, the two auxiliary plates 7 and the extension block 10 are provided with the gasket 3. The specific installation position of the sealing gasket 3 is given, so that the sealing gasket 3 can prevent external impurities from entering the ball 5, and the device can run more stably.

In the embodiment, because the production and processing modes of the bearing and the bearing protection seat are different, the dimensional accuracy of the two parts is different; during pressing, due to the fact that the position and the pressing force are different during pressing caused by the size difference of two parts and the size difference of parts, the coaxiality consistency of a pressed bearing and a bearing protection seat is poor, and the gap change of a bearing clearance bearing ball, an inner ring and an outer ring is large due to the pressing force. The installation of bearing needs outside article to pound hits or the instrument presses into, and this process is inevitable can the problem, and to different scenes, some interference fit's channel is too big or the undersize, all is difficult to install the bearing. Break through current thinking, at this installation department 4 of one side installation of bearing inner race 1, this bearing is installed to installation department 4 to reduce and exempt from current hitting, the instrument installation, and diminish to the channel of installation or other auxiliary mounting spare demands, the suitability is wider relatively, has had higher promotion for prior art. The provision of the circular pits 6 and the extensions 10 makes the bearing operate more stably.

After the bearing is installed, the installation part 4 may be hit by a foreign object, and the installation effect of the bearing may be affected. To this end, anti-pounding devices have been designed to divide the force of the pounding. When a foreign object smashes one of the protection plates 11 or a plurality of protection plates 11, the protection plate 11 drives the lower pressing plate 17 to move downwards, the lower pressing plate 17 buffers the smashing force through the second elastic piece 16, the lower pressing plate 17 moving downwards enables the two sliding sub pressing plates 14 to move towards two sides through the two hinge strips 15, the sliding sub pressing plates 14 moving towards two sides buffer the smashing force through the first elastic pieces 13, the force direction is 90 degrees, and therefore the influence caused by the smashing force is greatly reduced.

The technical scope of the present invention is not limited to the content in the above description, and those skilled in the art can make various modifications and alterations to the above embodiments without departing from the technical spirit of the present invention, and these modifications and alterations should fall within the protection scope of the present invention.
