Abstract
The utility model relates to bearing technical field, in particular to an insert bearing with full-spherical surface seal for occasions requiring low rotation speed and heavy load bearing; the insert bearing is composed of a bearing inner ring, an outer ring and steel balls arranged between the inner ring and the outer ring; ball placement holes are machined on the same end surfaces of the bearing inner ring and outer ring, the ball placement holes are conical holes, the diameter of ball placement holes on end surface is larger than the diameter of interior of ball placement holes. The utility model increases the number of steel balls through changing the ball placement mode so that the bearing can bear higher rated load; besides, the seal ring arranged on the insert bearing can effectively prevent dust and impurity from entering bearing and damaging steel balls so that the service life of insert bearing is improved.
Description
Technical field
The utility model relates to technical field of bearings, especially a kind of full ball sealing bearing with spherical outside surface that is applicable to that rotating speed is low, bearing load heavily waits occasion.
Background technique
The bearing with spherical outside surface major part is to be used for equipment such as farm machinery, mining machinery, belt system, rate request is low, the part occasion requires bearing can bear bigger rated load, the dress steel ball is all realized by retainer in the existing bearing with spherical outside surface, but its institute's steel ball number of adorning is less, make the bearing load of bearing be subjected to certain restriction, therefore can not be applicable to the heavy load occasion.
The model utility content
The utility model provides a kind of full ball sealing bearing with spherical outside surface, to solve this technical problem that original bearing can not bear heavy load.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of full ball sealing bearing with spherical outside surface, by bearing inner race, outer ring and place inner ring and the outer ring between steel ball form, same end face in bearing inner race and outer ring offers dress ball hole, dress ball hole is a taper hole, and the diameter in the dress ball hole of end is greater than the diameter of its inside.
Further, after making steel ball pack in the bearing, do not rebound out, the little internal diameter of dress ball Kongzui than steel ball size to 0.1～0.3mm when young.
Further, in order to prevent that things such as dust from entering bearing internal contamination steel ball, at an end that offers dress ball hole seal ring is housed on bearing inner race and the outer ring, seal ring is made of skeleton and caulking gum, and seal ring is provided with the tongue piece in sealing dress ball hole in the position corresponding to dress ball hole.
The utility model makes that by changing dress ball mode steel ball number increases greatly in the bearing, make bearing can bear bigger rated load, in addition, the seal ring that is provided with on the bearing can prevent effectively that thing such as dust from entering infringement steel ball in the bearing, increased the working life of bearing.

Wherein: 1, outer ring, 2, inner ring, 3, seal ring, 3-1, skeleton, 3-2, caulking gum, 3-3, tongue piece, 4, steel ball, 5, dress ball hole.
Embodiment
With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the schematic representation of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As Figure 1-3, a kind of full ball sealing bearing with spherical outside surface, by bearing inner race 2, outer ring 1 and place inner ring 2 and outer ring 1 between steel ball 4 form, same end face in bearing inner race 2 and outer ring 1 offers dress ball hole 5, dress ball hole 5 is a taper hole, and the diameter in the dress ball hole 5 of end is greater than the diameter of its inside.After making steel ball pack in the bearing, do not rebound out, dress ball hole 5 minimum diameters than steel ball 4 diameters to 0.1～0.3mm when young.In order to prevent that things such as dust from entering bearing internal contamination steel ball, at an end that offers dress ball hole 5 seal ring 3 is housed on bearing inner race 2 and the outer ring 1, seal ring 3 is made of skeleton 3-1 and caulking gum 3-2, and seal ring 3 is provided with the tongue piece 3-3 in sealing dress ball hole 5 in the position corresponding to dress ball hole 5.
