Utility model content

The purpose of this utility model is in that to provide a kind of bearing being prone to add oils and fats, with the problem solving to propose in above-mentioned background technology.

nullFor achieving the above object，This utility model provides following technical scheme: a kind of bearing being prone to add oils and fats，Including outer ring、Inner ring and ball，The inner chamber of described outer ring has the 3rd groove，The left and right sides, described outer ring outer wall all leaves the 4th groove，The outer wall of described inner ring has the first groove，The left and right sides, top of described inner ring is provided with screw thread，And first groove between the left and right sides, the top screw thread of inner ring，Described ball is between outer ring and inner ring，And the surface of ball is slidably connected with the cell wall of the cell wall of the first groove and the 3rd groove respectively，Described bearing cap is between outer ring and inner ring，Described bearing cap is connected by screw thread is fixing with the outer wall of inner ring，And the cell wall laminating of the inwall of bearing cap and the 4th groove，The inwall of described bearing cap has the second groove，And second the surface of cell wall and ball of groove be slidably connected，The outer wall of described bearing cap uniformly has oil filler point.

Preferably, the outer wall of described bearing cap is socketed with the sealing ring of ring-type.

Preferably, described first groove, the second groove and the 3rd groove are arc groove.

Preferably, described oil filler point is arranged at the outer wall of the second groove.

Compared with prior art, the beneficial effects of the utility model are: be originally prone to add the bearing of oils and fats, adopt and bearing cap is set between outer ring and inner ring, the oils and fats avoiding Bearing inner throws away from Bearing inner, the dust and the foreign material that are prevented from the external world enter Bearing inner simultaneously, affect the normal rotation of bearing, the outer wall of bearing cap and inner ring is spirally connected, easy to removal and installation, bearing is provided with oil filler point on this, it is easy to add oils and fats toward Bearing inner, the inwall of bearing cap is provided with annular groove simultaneously, ball in bearing and groove surface are slidably connected, ensure that lateral displacement will not occur the ball in bearing, ball is avoided to shake at Bearing inner, this bearing being prone to add oils and fats is prone to add oils and fats, high lubricating effect, decrease oils and fats and make consumption, long service life.

Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.

nullRefer to Fig. 1-4，This utility model provides a kind of technical scheme: a kind of bearing being prone to add oils and fats，Including outer ring 1、Inner ring 2 and ball 4，The inner chamber of outer ring 1 has the 3rd groove 9，The left and right sides, outer ring 1 outer wall all leaves the 4th groove 10，The outer wall of inner ring 2 has the first groove 6，The left and right sides, top of inner ring 2 is provided with screw thread 7，And first groove 6 between the left and right sides, the top screw thread 7 of inner ring 2，Ball 4 is between outer ring 1 and inner ring 2，And the surface of ball 4 is slidably connected with the cell wall of the first groove 6 and the cell wall of the 3rd groove 9 respectively，Bearing cap 3 is between outer ring 1 and inner ring 2，Bearing cap 3 is connected by screw thread 7 is fixing with the outer wall of inner ring 2，And the cell wall laminating of the inwall of bearing cap 3 and the 4th groove 10，The outer wall of bearing cap 3 is socketed with the sealing ring of ring-type，The oils and fats avoiding Bearing inner throws away from Bearing inner，The dust and the foreign material that are prevented from the external world enter Bearing inner simultaneously，Improve the lubricating ability of this bearing，What decrease lubricating oil makes consumption，The inwall of bearing cap 3 has the second groove 8，And second the surface of cell wall and ball 4 of groove 8 be slidably connected，First groove 6、Second groove 8 and the 3rd groove 9 are arc groove，Ensure that the ball 4 normal rolling at Bearing inner，The outer wall of bearing cap 3 uniformly has oil filler point 5，Oil filler point 5 is arranged at the outer wall of the second groove 8，It is easy to inject oils and fats to Bearing inner，Concurrently injected oils and fats can contact with the surface of ball 4 fully at the inner chamber of the second groove 8，In the rotation by ball 4，Oils and fats can be made to be evenly distributed in the inside of bearing.
