Abstract
The utility model relates to a bearing with the axial buffering function, which includes a bearing left cover and a bearing right cover arranged at an interval, wherein a rolling bearing sleeve is arranged between the bearing left cover and the bearing right cover; the bearing left cover, the bearing right cover and the rolling bearing sleeve are fixed into a whole; an inner ring body is arranged inside the rolling bearing sleeve; an outer ring body is arranged outside the inner ring body; a rolling body is arranged between the inner ring body and the outer ring body; an axial preloaded spring is arranged on the bearing right cover, and is propped against the right end surface of the outer ring body; an oil thrower preloaded ring is arranged between the left side of the inner ring body and the right side of the bearing left cover; the right end surface of the oil thrower preloaded ring is propped against the left end surface of the inner ring body; and the left end surface of the oil thrower preloaded ring is propped against the right end surface of a shaft used check ring on a rotating shaft. The utility model enables the whole air side deep groove ball bearing device to be not limited in the axial direction, and prevents shaft-seizure and burn-out accidents caused by the condition that both head and tail sides of the rotating shaft are limited.
Description
Technical field
The utility model relates to a kind of bearing, especially a kind of bearing with axial buffer effect.
Background technique
In the production process of power station and large enterprise, motor is main power source, in case break down, the loss that whole production is brought is sizable, and especially large and medium-sized high-tension motor can badly influence whole process of production.Statistics according to electrical fault finds that damage of bearings or the electrical fault that causes because of damage of bearings have accounted for more than 70% of the whole faults of motor.
In the more novel medium and small box motor that China is produced at present, load side adopts single " deep groove ball bearing " usually, and empty side then is single " roller bearing "; In this structure, deep groove ball bearing axially has limit stoper, and roller bearing is axially then not spacing; Owing to compare deep groove ball bearing, operating temperature of empty side cylindrical bearing and noise are all than higher, and be inapplicable gradually concerning the wind power system that low noise, high reliability request are arranged; But empty side is as also changing the deep groove ball bearing device into, and then the deep groove ball bearing of empty side axially must be not spacing, this ball bearing axially not limit structure many difficulties are arranged in realization.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that exists in the existing technology, and a kind of bearing with axial adjustment effect is provided.
The technological scheme that provides according to the utility model; Said bearing with axial buffer effect; Comprise the bearing left side lid and the right lid of bearing that are provided with at interval, between bearing left side lid and the right lid of bearing, be provided with axis of rolling bearing sleeve, bearing left side lid, the right lid of bearing are fixed as one with axis of rolling bearing sleeve; Be provided with inner ring body in axis of rolling bearing sleeve inside; Outside at inner ring body is provided with outer ring body, between inner ring body and outer ring body, is provided with rolling element, has the gap between the right side of bearing left side lid and the left side of inner ring body and between the left side of the right side of bearing left side lid and outer ring body; Has the gap between the left side of the right lid of bearing and the right side of inner ring body and between the right side of the left side of the right lid of bearing and outer ring body; Cover on the bearing right side and to be provided with the axial pretightening spring, the axial pretightening spring is against on the right side of outer ring body, between the right side of the left side of inner ring body and bearing left side lid, is provided with the disc preload ring; The right side of disc preload ring and the left side of inner ring body offset, and the left side of disc preload ring and the right side of the shaft block ring on the running shaft offset.
On the right rotation shaft hole inner wall that covers of rotation shaft hole inner wall, bearing of bearing left side lid, be provided with oil-sealing arrangement.
In bearing left side lid and axis of rolling bearing sleeve, offer the oilhole that is communicated with, the oil outlet of oilhole joins with the left side that the bearing right side is covered.
The utility model makes that whole empty side deep groove ball bearing assembly axis is spacing to right and wrong, prevents all limited and issuable seize burnout failure in running shaft head and the tail both sides.
Description of drawings
Fig. 1 is the overall structure schematic representation of the utility model.
Embodiment
Below in conjunction with concrete accompanying drawing and embodiment the utility model is described further.
As shown in the figure: this has the bearing of axial buffer effect; Comprise the bearing left side lid 1 and the right lid 2 of bearing that are provided with at interval; Between bearing left side lid 1 and the right lid 2 of bearing, be provided with axis of rolling bearing sleeve 3; Bearing left side lid 1, the right lid 2 of bearing are fixed as one with axis of rolling bearing sleeve 3, are provided with inner ring body 4 in axis of rolling bearing sleeve 3 inside, are provided with outer ring body 5 in the outside of inner ring body 4; Between inner ring body 4 and outer ring body 5, be provided with rolling element 6; Have the gap between the right side of bearing left side lid 1 and the left side of inner ring body 4 and between the left side of the right side of bearing left side lid 1 and outer ring body 5, have the gap between the left side of the right lid 2 of bearing and the right side of inner ring body 4 and between the right side of the left side of the right lid 2 of bearing and outer ring body 5, on the right lid 2 of bearing, be provided with axial pretightening spring 7; Axial pretightening spring 7 is against on the right side of outer ring body 5; Between the right side of the left side of inner ring body 4 and bearing left side lid 1, be provided with disc preload ring 8, the left side of the right side of disc preload ring 8 and inner ring body 4 offsets, and the right side of the shaft block ring 12 on the left side of disc preload ring 8 and the running shaft 11 offsets.
On the rotation shaft hole inner wall of the rotation shaft hole inner wall of bearing left side lid 1, the right lid 2 of bearing, be provided with oil-sealing arrangement 9.
In bearing left side lid 1 and axis of rolling bearing sleeve 3, offer the oilhole 10 that is communicated with, the oil outlet of oilhole 10 and the bearing right side are covered 2 left side and are joined.
The utility model makes outer ring body 5 receive pretension on the one hand, and bearing clearance is squeezed to desirable zero windage, and bearing noise and temperature rise situation all improve; On the other hand; Axial pretightening spring 4 has self-adjustment capability; When empty side bearing device receives axial float, can play buffer function, make that whole empty side deep groove ball bearing assembly axis is spacing to right and wrong, prevent all limited and issuable seize burnout failure in running shaft 11 head and the tail both sides.
