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
The present invention relates to a kind of lapping machine bearing, specifically a kind of liquid crystal lens lapping machine two-row ball bearing.
Background technique
Bearing belongs to one of core component of lapping machine, its precision directly affects the performance standard of lapping machine and the lens quality of producing, making the single-row angular contact ball bearing of common employing on the employed lapping machine of liquid crystal lens, but single-row angular contact ball bearing can only bear the thrust load of a direction, kind of bearings is when bearing pure radial load, because rolling element load line and Radial Loads line be not in same radial plane, produce inner axial thrust load, so must paired mounting use, and installation has increased equipment size, the precision that very difficult realization is higher in pairs.
Summary of the invention
The object of the present invention is to provide a kind of liquid crystal lens lapping machine two-row ball bearing, solve the liquid crystal lens machine and adopt single-row angular contact ball bearing can not realize high-precision problem.
The technical solution adopted for the present invention to solve the technical problems is: a kind of liquid crystal lens lapping machine two-row ball bearing, comprise outer ring, inner ring, steel ball and retainer, it is characterized in that, described inner ring is two, inner ring is provided with steel-ball groove, two inner rings vertically two steel-ball grooves that make placed side by side are centrosymmetric, be placed with steel ball in the steel-ball groove, steel ball is evenly separated by retainer, cover has the outer ring in the outside of steel ball, the interior edge face of outer ring is provided with two seal grooves, is fixed with seal ring in the seal groove, and the internal diameter of seal ring cooperates with the crest clearance of inner ring.
The biserial channel structure is adopted in described outer ring.
The ditch heart distance of described outer ring raceway is 28mm.
Described steel ball and inner ring adopt angle contacting, and wrapping angle is 30 °.
The invention has the beneficial effects as follows: the present invention adopts the Double-row ball design, axial stability that can the Effective Raise bearing, and can take less axial space, can bear radial load and from the load on the axial both direction, can provide rigidity higher axial arrangement, and can bear tilting moment.
Description of drawings
Fig. 1 is structural representation of the present invention.
Among the figure: 1 outer ring, 2 inner rings, 3 steel balls, 4 retainers, 5 seal grooves, 6 seal rings.
Embodiment
As shown in Figure 1, a kind of liquid crystal lens lapping machine two-row ball bearing, comprise outer ring 1, inner ring 2, steel ball 3 and retainer 4, described inner ring 2 is two, inner ring 2 is provided with steel-ball groove, two inner rings 2 vertically two steel-ball grooves that make placed side by side are centrosymmetric, be placed with steel ball 3 in the steel-ball groove, steel ball 3 is evenly separated by retainer 4, cover has outer ring 1 in the outside of steel ball 3, the interior edge face of outer ring 1 is provided with two seal grooves 5, is fixed with seal ring 6 in the seal groove 5, and the internal diameter of seal ring 6 cooperates with the crest clearance of inner ring 2.
The biserial channel structure is adopted in described outer ring 1.
The ditch heart of described outer ring 1 raceway groove has formed fixing axial moment apart from being 28mm, has overcome the shortcoming that existing bearing 61952M can only come with play the axial displacement of limit mechanical.
Described steel ball 3 adopts angle contacting with inner ring 2, and wrapping angle is 30 °, has increased simultaneously dress nodule number amount, has improved accordingly the load of bearing, has more improved whole antiwhip.
The present invention adopts steel ball biserial design, axial stability that can the Effective Raise bearing, and two-row ball bearing, can take less axial space, can bear radial load and from the load on the axial both direction, can provide rigidity higher axial arrangement, and can bear tilting moment.
The present invention has increased Seal Design, and its seal form is that outer ring 1 is fastened on seal groove 5, seal ring 6 in the seal groove 5 of outer ring, and seal ring 6 has certain radial clearance with inner ring 2, is the non-contact sealing.Major advantage be simple in structure, easy to process, assembling easily, little, the heating of frictional force less during bearing rotary, high speed performance is good etc.
