Abstract
The utility model relates to the technical field of ball bearings, in particular to a self-aligning ball bearing with a cylindrical bore, which is applied in a multi-support transmission shaft, a double-support bearing with large bending under outer load and parts where supporting seat holes are not easy to be strictly concentric. The self-aligning ball bearing with the cylindrical bore comprises a bearing outer ring, balls and a bearing inner ring. The double-row balls are distributed between the bearing outer ring and the bearing inner ring. A roller path of the bearing outer ring is a spherical roller path, and two arc grooves are arranged on the spherical roller path of the bearing inner ring. The self-aligning ball is simple in structure, easy to process, small in friction factor and good in self-aligning performance.
Description
Technical field
The utility model relates to the selfaligning ball bearing technical field, especially a kind ofly is applicable to the multi-support transmission shaft, under external load, has than the dual-supporting axle of macrobending and supporting base hole and be difficult for guaranteeing the cylindrical hole selfaligning ball bearing in the strict concentric parts.
Background technique
The selfaligning ball bearing friction factor of present common use is big, can not adapt to the very big situation that runs up of thrust load, and working life is not long, and working efficiency is not high, and often with changing and repair bearing, cost of production also rises thereupon.
The model utility content
The technical problem that the utility model will solve is: overcome the deficiency in the existing technology, provide a kind of simple in structure, the cylindrical hole selfaligning ball bearing that using effect is good.
The utility model solves the technological scheme that its technical problem adopted: a kind of cylindrical hole selfaligning ball bearing; Comprise bearing outer ring, spin and bearing inner race; Described double ball is arranged between bearing outer ring and the bearing inner race; The raceway of bearing outer ring is a sphere shape raceway, and the raceway of bearing inner race is provided with two arc grooves.
The beneficial effect of the utility model is: the utility model is simple in structure, is easy to processing, and friction factor is little, and the self-aligning performance is good.
Description of drawings
Below in conjunction with accompanying drawing and mode of execution the utility model is further specified.
Fig. 1 is the structural representation of the utility model.
1. bearing outer rings among the figure, 2. spin, 3. bearing inner race.
Embodiment
Combine accompanying drawing that the utility model is further described now.The schematic representation that these accompanying drawings are simplification is only explained the basic structure of the utility model in a schematic way, so it only shows the formation relevant with the utility model.
A kind of cylindrical hole selfaligning ball bearing as shown in Figure 1; Comprise bearing outer ring 1, spin 2 and bearing inner race 3; Described double ball 2 is arranged between bearing outer ring 1 and the bearing inner race 3, and the raceway of bearing outer ring 1 is a sphere shape raceway, and the raceway of bearing inner race 3 is provided with two arc grooves.
Above-mentioned mode of execution is only for explaining the technical conceive and the characteristics of the utility model; Its purpose is to let the personage that is familiar with this technology can understand the content of the utility model and implements; Can not limit the protection domain of the utility model with this; All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed in the protection domain of the utility model.
