Abstract
The utility model provides a height bears weight of spacer ring punching press holder biserial self -aligning roller bearing in nothing, includes outer lane and inner circle, be equipped with between outer lane and inner circle set up side by side two be listed as the holder, be equipped with the pocket hole that a plurality of has pocket hole lock points respectively along the circumference on every holder, at the downthehole rolling element of installing respectively of every pocket. The above technical scheme is adopted in the utility model, structural design is equitable, and through spacer ring in the activity of cancellation in the primary structure, in limited bearing inner space, the length of rolling element obtains the increase, the rated load of bearing improves by a wide margin, has eliminated in the activity inertia of spacer ring in frictional resistance and the activity between spacer ring and holder, the rolling element simultaneously, has reduced the idle consumption of bearing inside, has improved the rated revolution of bearing.
Description
Technical field:
The utility model relates to a kind of high-mechanic without middle spacer ring pressing cage double-row self-aligning roller bearing.
Background technique:
The structure of existing CC type selfaligning roller bearing as shown in Figure 1, it comprises outer ring 1 and inner ring 2, two row retainers 4 are provided with between outer ring 1 and inner ring 2, each retainer 4 is respectively equipped with several rolling elements 3, between two retainers 4, be provided with spacer ring 5 in an activity, in this structure, in activity, the object of spacer ring 5 guides retainer 4 and rolling element 3.Due to the existence of spacer ring in activity 5, the CC type selfaligning roller bearing of this kind of structure has following shortcoming: one is relative sliding friction between spacer ring 5 in rolling element 3 and activity, produces heat; Two is relative sliding frictions between spacer ring 5 in retainer 4 and activity, creates heat; Three are the increase in the rotary inertia in bearing, and reactive power consumption is large; Four is that the length of rolling element 3 is subject to spatial constraints, relatively short, thus causes the bearing capacity of bearing relatively low.
Model utility content:
The utility model is in order to make up the deficiencies in the prior art, provide a kind of high-mechanic without middle spacer ring pressing cage double-row self-aligning roller bearing, its reasonable in design, by cancelling spacer ring in the activity in original structure, in limited bearing interior space, the length of rolling element is increased, the load rating of bearing significantly improves, eliminate spacer ring and retainer in activity simultaneously, the rotary inertia of spacer ring in surface friction drag between rolling element and activity, reduce the reactive power consumption of Bearing inner, improve the rated speed of bearing, solve problems of the prior art.
The utility model for solving the problems of the technologies described above adopted technological scheme is:
A kind of high-mechanic is without middle spacer ring pressing cage double-row self-aligning roller bearing, comprise outer ring and inner ring, the two row retainers be arranged side by side are provided with between outer ring and inner ring, each retainer is circumferentially respectively equipped with several lock point pocket hole with pocket hole, in each pocket hole, a rolling element is installed respectively.
Angle between the pocket hole inwall that some side are locked in the inclined-plane at lock point place, described pocket hole and pocket hole is 20-30 degree.
The utility model adopts such scheme, reasonable in design, by cancelling spacer ring in the activity in original structure, in limited bearing interior space, the length of rolling element is increased, and the load rating of bearing significantly improves, and eliminates the rotary inertia of spacer ring in surface friction drag between spacer ring and retainer in activity, rolling element and activity simultaneously, reduce the reactive power consumption of Bearing inner, improve the rated speed of bearing.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of existing CC type selfaligning roller bearing.
Fig. 2 is sectional structure schematic diagram of the present utility model.
Fig. 3 is perspective view of the present utility model.
Fig. 4 is the structural representation of retainer of the present utility model.
Fig. 5 is the A portion enlarged view in Fig. 4.
In figure, 1, outer ring, 2, inner ring, 3, rolling element, 4, retainer, 5, spacer ring in activity, 6, pocket hole, 7, pocket hole lock point.
Embodiment:
For clearly demonstrating the technical characterstic of this programme, below by embodiment, and in conjunction with its accompanying drawing, the utility model is elaborated.
As shown in Figure 2-5, a kind of high-mechanic is without middle spacer ring pressing cage double-row self-aligning roller bearing, comprise outer ring 1 and inner ring 2, the two row retainers 4 be arranged side by side are provided with between outer ring 1 and inner ring 2, each retainer 4 is circumferentially respectively equipped with several lock point 7 pocket hole 6 with pocket hole, a rolling element 3 is installed respectively in each pocket hole 6.
Angle between pocket hole 6 inwall that a little 7 side are locked in the inclined-plane at lock point 7 places, described pocket hole and pocket hole is 20-30 degree.Pocket hole lock point 7 adopts novel shearing processing technology to process, and the guidance mode between rolling element 3 and retainer 4 is optimized, rolling element 3 smooth running in pocket hole 6, and surface friction drag reduces greatly.
Adopt high-mechanic of the present utility model without middle spacer ring pressing cage double-row self-aligning roller bearing, by cancelling spacer ring 5 in the activity in original structure, in limited bearing interior space, the length of rolling element is increased, the load rating of bearing significantly improves, eliminate spacer ring and retainer in activity simultaneously, the rotary inertia of spacer ring in surface friction drag between rolling element and activity, reduce the reactive power consumption of Bearing inner, improve the rated speed of bearing, the section thickness of retainer also can strengthen the intensity strengthening retainer, avoid retainer premature fatigue failure.
The utility model does not describe part in detail, is the known technology of those skilled in the art of the present technique.
