Embodiment Construction

[0011] Such as figure 1 As shown, a double-row ball bearing for a liquid crystal lens lapping machine includes an outer ring 1, an inner ring 2, a steel ball 3 and a cage 4, the inner ring 2 is two, and the inner ring 2 is provided with a steel The ball groove, the two inner rings 2 are placed side by side in the axial direction so that the two steel ball grooves are symmetrical to the center, steel balls 3 are placed in the steel ball groove, the steel balls 3 are evenly separated by the cage 4, and the outer side of the steel ball 3 is sleeved Two sealing grooves 5 are arranged on the inner end surface of the ring 1 and the outer ring 1, and a sealing ring 6 is fixed in the sealing groove 5, and the inner diameter of the sealing ring 6 is in clearance fit with the outer diameter of the inner ring 2.

[0012] The outer ring 1 adopts a double row channel structure.

[0013] The distance between the centers of the channels of the outer ring 1 is 28 mm, forming a fixed axial mo...

Abstract

The invention provides a double-row ball bearing for a liquid crystal lens lapping machine and relates to a bearing for the lapping machine. The problem that high accuracy of a liquid crystal lens machine cannot be achieved due to the use of single-row angular contact ball bearing is solved. The double-row ball bearing comprises outer rings, inner rings, steel balls and a retainer and is characterized in that the two inner rings are arranged; steel ball grooves are formed in the inner rings; the two inner rings are axially arranged in parallel, so that the two steel ball grooves are centrosymmetric; steel balls are placed in the steel ball grooves; the steel balls are uniformly partitioned through the retainer; the outer rings are sleeved on the external sides of the steel balls; two sealed grooves are formed in the inner end surfaces of the outer rings; sealing rings are fixed in the sealing grooves; and the internal diameters of the sealing rings are in clearance fit with the external diameters of the inner rings. According to the invention, through adoption of the double-row steel ball design, the axial stability of the bearing can be effectively improved, a smaller axial space can be occupied, radial load and axial loads in two directions can be born, axial configuration with higher rigidity can be provided and overturning moment can be born.

Description

technical field [0001] The invention relates to a bearing for a lapping machine, in particular to a double-row ball bearing for a lapping machine for liquid crystal lenses. Background technique [0002] The bearing is one of the core components of the lapping machine, and its precision directly affects the performance standard of the lapping machine and the quality of the lens produced. Single-row angular contact ball bearings are usually used in the lapping machine used to make liquid crystal lenses, but the single-row angular contact Contact ball bearings can only bear axial load in one direction. When this type of bearing bears pure radial load, since the load action line of the rolling element and the radial load action line are not in the same radial plane, an internal axial component force is generated. Therefore, it must be installed and used in pairs, and the installation in pairs increases the size of the equipment, making it difficult to achieve higher precision. ...
