It is able to satisfy the spring catch entity copper retainer cylinder roller bearing of the one of outer ring guidance or inner ring guidance.
To achieve the goals above, the technical solution of the utility model is: a kind of machine tool chief axis or gearbox band
The copper cage cylinder roller bearing of spring catch, including inner ring, outer ring, copper cage and rolling element, it is characterised in that: the copper
Retainer is the integral structure being made of interior lateral margin, lateral border and several post holes crossbeams；Between the interior lateral margin and lateral border
It is connected with post holes crossbeam；Space between the adjacent post holes crossbeam forms post holes, is post holes among the two sides of post holes crossbeam
Wall, the two sides of post holes wall 3 are plane；The interior lateral margin at the post holes both ends and lateral border are equipped with pin hole；The two of the rolling element
End is equipped with depression, and rolling element is lockked by the spring catch being located in the pin hole of two sides.
Spring catch described in the technical solution of the utility model is rolled by steel spring plate, and centre forms axial circular
Hole, circular hole both ends are equipped with chamfering.
Pin hole described in the technical solution of the utility model is circular hole.
Spring steel plate thickness 0.35mm described in the technical solution of the utility model, and it is quenched processing.
The plane of post holes wall two sides described in the technical solution of the utility model and the axial line of adjacent rolling elements
It is parallel with the plane of cylinder roller bearing central axis lock.
Depression described in the technical solution of the utility model and cylinder roller bearing central axis are concentric.
Spring catch outer diameter described in the technical solution of the utility model and depression hole wall have 50 millimeters of 0.35-0.
Gap.
The utility model compared with prior art, has the following advantages that and effect: reasonable integral structure, retainer one
Body structure meets outer ring guidance or inner ring guidance, spring catch passes through roller using having high-intensitive, high revolving speed and long-life
Depression guarantees that the outer diameter of roller does not conform to post jamb contact, guarantees low vibration and low noise, realizes good lubrication and Homogeneouslly-radiating, weight
Gently and make it have superperformance and easy to process, assembly technology simplification, raising assembly efficiency.

Specific embodiment
The utility model is further described below in conjunction with attached drawing.
Shown in referring to Figure 1 to Figure 7, the utility model machine tool chief axis or gearbox are rolled with the copper cage cylinder with spring catch
Sub- bearing includes inner ring, outer ring, copper cage and rolling element, and rolling element is cylindrical roller 6.Copper cage is by interior lateral margin 8, outside
The integral structure of lateral margin 7 and several post holes crossbeams 5 composition.Wherein, connected between interior lateral margin 8 and lateral border 7 with post holes crossbeam 5
It connects, the space between adjacent post holes crossbeam 5 forms post holes.It is post holes wall 3 among the two sides of post holes crossbeam 5, the two of post holes wall 3
Side is the flat of plane, the plane of 3 two sides of post holes wall and the axial line of adjacent rolling elements and cylinder roller bearing central axis lock
Face is parallel.The interior lateral margin 8 at post holes both ends and lateral border 7 are equipped with pin hole 4, and pin hole 4 is circular hole.The both ends of cylindrical roller 6 are equipped with
Depression 2, depression 2 and cylinder roller bearing central axis are concentric.Spring catch 1 is rolled by the steel spring plate of thick 0.35mm, intermediate shape
At axial circular hole, circular hole both ends are equipped with chamfering, and are quenched processing.1 outer diameter of spring catch and 2 hole wall of depression have 50 milli of 0.35-0.
Rice gap.Cylindrical roller 6 is lockked by the spring catch 1 being located in two sides pin hole 4.
Since the utility model is designed to outer ring guidance or inner ring guidance, to reduce the weight of retainer, both subtracted
Small centrifugal action of the bearing in operation process, and can solve heat dissipation and lubrication problem, while in turn ensuring the high revolving speed of bearing,
To realize the low vibration and low noise of bearing.
Since the utility model is suitable for precision equipment, limit speed is higher, and bearing capacity requirement is also very high, passes through copper
Spring catch 1 and depression 2 on retainer fix cylindrical roller 6 relatively.
When cylindrical roller 6 is installed, first inner ring is installed, then the cylindrical roller 6 by both ends with depression 2 is packed into post holes from collar extension
It is interior, finally outer ring is put on.First outer ring can also be installed, cylindrical roller 6 is packed into post holes from internal orifice, it then will be interior
On snare.Spring catch 1 is bumped into depression 2.
The utility model compared with prior art, has the advantage that structure is simple and easy to process, saves material, makes
Cost is greatly lowered；Since 6 outer diameter of cylindrical roller discord post holes wall 3 contacts, the center portion revolving speed of depression 2 is extremely low and pin friction
Coefficient is small, and noise reduction and damping property are good；Tensile strength is high；Greasy property is good, and bearing is made to obtain structure optimization, and bearing life can mention
It is 2 times high.Its social benefit and Business Economic Benefit improve.
