Abstract
The utility model discloses a bearing for a mine hoist, and relates to bearings. The bearing comprises inner and outer rings, wherein rollers which are spaced by a retainer is arranged between the inner and outer rings, the roller adopts an English system taper roller structure, and a contacting angle between an outer ring raceway and the roller is 983 minutes; and the contacting angle between an inner ring raceway and the roller is 939 minutes, and the load center is 14.2 mm. The bearing provided by the utility model has the advantages that the contacting angles between the inner ring raceway and the roller, and between the outer ring raceway and the roller are increased, the load-carrying capacity of the bearing is improved, the service life of the bearing is prolonged, and the serviceability of the bearing is increased.
Description
Technical field
The utility model relates to a kind of bearing, specifically the mine hoist bearing.
Background technique
The mine hoisting machine bearing is the important component part of lift, reinforcement along with domestic bargh exploitation dynamics, the utilization of large-scale excavation machinery, to the requirement of lift to high-power, the direction of high loading develops, therefore to the load-carrying ability of mine hoisting machine bearing and working life also improved usage requirement, in order to adapt to the demand of high-power high loading, need the bearing of a kind of more high loadability, longer service life.
The model utility content
The purpose of this utility model is to provide a kind of mine hoist bearing, solves the above problems.
The technological scheme that its technical problem that solves the utility model adopts is: the mine hoist bearing, it is characterized in that, comprise inner ring and outer ring, also be provided with the roller that separates by retainer between inner ring and the outer ring, described roller adopts tapered roller structure made in Great Britain, the wrapping angle of described outer ring raceway and roller is 16 ° 23 ' 00 ", the wrapping angle of inner ring raceway and roller is 15 ° 39 ' 00 ", load center is 14.2mm.
The beneficial effects of the utility model are: by increasing the wrapping angle of Internal and external cycle raceway and roller, the load-carrying ability and the working life of having improved bearing, increased the operational safety of bearing.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 inner ring, 2 outer rings, 3 rollers.
Embodiment
As shown in Figure 1, the mine hoist bearing, comprise inner ring 1 and outer ring 2, also be provided with the roller 3 that separates by retainer between inner ring 1 and the outer ring 2, described roller 3 adopts tapered roller structure made in Great Britain, the wrapping angle of described outer ring raceway and roller is 16 ° 23 ' 00 ", the wrapping angle of inner ring raceway and roller is 15 ° 39 ' 00 ", load center is 14.2mm.
According to bearing basic dynamic radial load rating and rating life formula, can draw the every minimizing 5% of effective length of the plain line of roller and inner ring raceway, the rating life of bearing will reduce about 12%, the utility model has strengthened the rolling surface angle of outer ring raceway and rolling element for this reason, the angle of the rolling surface of inner ring raceway and rolling element, adjust large-flange angle and bearing load center, improved the load rating of bearing greatly, guaranteed the ability that bearing can bear bigger load.Roller 3 adopts tapered roller structure made in Great Britain, promptly can bear radial load, can bear the thrust load of part again, is designed to mounted in pairing mode and uses in the gearbox of lift, has improved the life-span of bearing and the reliability of bearing.
After adopting the utility model scheme, increased the load-carrying ability of bearing greatly, density of load increase rate reaches more than 30 percent.Contrast table is as follows:
