Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of generators, in particular to an axial displacement control device for a ball bearing at the fixed end of a shafting. Background Technique
[0002] A bearing is an important component in contemporary mechanical equipment. Its main function is to support a rotating mechanical body, reduce the friction coefficient during its movement, and ensure its rotational accuracy. According to the different friction properties of moving elements, bearings can be divided into two major categories: rolling bearings and sliding bearings. Among them, rolling bearings have been standardized and serialized, but compared with sliding bearings, they have larger radial dimensions, vibration, and noise, and higher prices.
[0003] The axial displacement of a ball bearing refers to the inevitable small movement of its inner and outer rings along the axial direction during operation, which will cause the vibration and noise of the mechanism to increase, thereby endangering the equipment and reducing its service life. Content of the Utility Model
[0004] The utility model aims to solve one of the technical problems existing in the prior art or related technologies.
[0005] For this reason, the technical solution adopted by the utility model is as follows:
[0006] An axial displacement control device for a ball bearing at the fixed end of a shafting includes a stabilizing mechanism and a pressing mechanism. The stabilizing mechanism includes a housing, a bearing movably sleeved outside the housing, and a ring body sleeved outside the bearing and connected to the housing. The pressing mechanism includes a pressing plate fitting on the outside of the bearing, a plurality of connecting legs connected to the pressing plate, a sleeve plate movably sleeved at the outer ends of the connecting legs and connected to the housing, an annular plate installed inside the sleeve plate, and a rubber pad connected to the annular plate. The inner end of the rubber pad fits with the balls inside the bearing.
[0007] By adopting the above technical solution, after the bearing is sleeved outside the housing, install the pressing plate so that the pressing plate fits on one side of the bearing, and correspondingly the rubber pad fits with the balls inside the bearing. Then insert the connecting legs into the sleeve plate and rotate the pressing plate, whereby the connecting legs can be clamped with the sleeve plate. Then the bearing and the balls inside it are both limited, thereby reducing the probability of the bearing moving, enabling the bearing to rotate stably, preventing harm to the equipment, and ensuring the service life of the equipment.
[0008] The utility model can be further configured in a preferred example as follows: A plurality of threaded holes are provided on the housing, and the plurality of threaded holes are arranged at equal intervals and in a ring shape.
[0009] The utility model can be further configured in a preferred example as follows: The width of the bearing is greater than the width of the ring body, and the ring body is integrally formed with the housing.
[0010] In a preferred embodiment of the present utility model, it can be further configured that: the pressing plate is movably sleeved outside the housing, and both the pressing plate and the annular plate are made of metal materials.
[0011] In a preferred embodiment of the present utility model, it can be further configured that: a plurality of sleeve plates are arranged at equal intervals in a circular arrangement, and the sleeve plates and the threaded holes are arranged alternately.
[0012] In a preferred embodiment of the present utility model, it can be further configured that: a positioning pin is movably inserted into the sleeve plate, and the positioning pin is movably inserted into the connecting leg.
[0013] By adopting the above technical solutions, the beneficial effects achieved by the present utility model are:
[0014] In the present utility model, after the bearing sleeve is sleeved outside the housing, the pressing plate is installed so that the pressing plate fits against one side of the bearing. Correspondingly, the rubber pad fits against the balls inside the bearing. Then, the connecting leg is inserted into the sleeve plate and the pressing plate is rotated, whereby the connecting leg can be clamped with the sleeve plate. Then, both the bearing and the balls inside it are limited, thereby reducing the probability of the bearing moving, enabling the bearing to rotate stably, preventing damage to the equipment, and ensuring the service life of the equipment.

[0026] The following describes an axial endplay control device for a fixed-end ball bearing of a shafting according to some embodiments of the present utility model with reference to the accompanying drawings.
[0027] Embodiment 1:
[0028] As shown in Figures 1-5 the axial endplay control device for a fixed-end ball bearing of a shafting provided by the present utility model includes a stabilizing mechanism 100 and a pressing mechanism 200. The stabilizing mechanism 100 includes a housing 110, a bearing 120 movably sleeved outside the housing 110, and a ring body 130 sleeved outside the bearing 120 and connected to the housing 110.
[0029] The pressing mechanism 200 includes a pressing plate 210 attached to the outside of the bearing 120, a plurality of connecting legs 220 connected to the pressing plate 210, a sleeve plate 230 movably sleeved at the outer ends of the connecting legs 220 and connected to the housing 110, an annular plate 240 installed inside the sleeve plate 230, and a rubber pad 250 connected to the annular plate 240. The inner end of the rubber pad 250 is in contact with the balls inside the bearing 120.
[0030] Furthermore, the width of the bearing 120 is greater than the width of the ring body 130. The ring body 130 is integrally formed with the housing 110. With this size design, it is ensured that the pressing plate 210 can press on the bearing 120, providing conditions for the pressing plate 210 to limit the position of the bearing 120.
[0031] Furthermore, the pressing plate 210 is movably sleeved outside the housing 110. The pressing plate 210 and the annular plate 240 are both made of metal materials. The pressing plate 210 and the annular plate 240 made of metal materials can firmly squeeze the bearing 120.
[0032] Furthermore, a plurality of sleeve plates 230 are arranged at equal intervals in a circular pattern. The sleeve plates 230 are arranged in a staggered pattern with the threaded holes, and the layout is reasonable, ensuring the aesthetics of the device.
[0033] Embodiment 2:
[0034] As shown in Figures 1-4As shown, based on the first embodiment, a plurality of threaded holes are provided in the housing 110. The plurality of threaded holes are arranged at equal intervals in a circular pattern. The provision of the threaded holes facilitates the connection of the housing 110 to external equipment.
[0035] Embodiment Three:
[0036] Combined with Figure 2 and Figure 4 As shown, in the above embodiment, a positioning pin 300 is movably inserted into the sleeve plate 230, and the positioning pin 300 is movably inserted into the connecting leg 220. The provision of the positioning pin 300 can fix the connecting leg 220, enabling the pressing plate 210 to stably press the bearing 120.
[0037] The working principle and usage process of the present utility model: When the device is put into actual use, when the bearing 120 is sleeved outside the housing 110 and restricted inside the ring body 130, the pressing plate 210 is installed so that the pressing plate fits against one side of the bearing 120, and the corresponding rubber pad 250 fits against the balls inside the bearing 120. Then, the connecting leg 220 is inserted into the sleeve plate 230, and the pressing plate 210 is rotated. Thereby, the connecting leg 220 can be engaged with the sleeve plate 230. Then, both the bearing 120 and the balls inside it are limited, thereby reducing the probability of the bearing 120 moving, enabling the bearing 120 to rotate stably, and preventing harm to the equipment.
[0038] Although the embodiments of the present utility model 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 principles and purposes of the present utility model.
