Abstract
The utility model provides a double-inclined-groove bearing, which comprises an outer ring, an inner ring and steel balls, wherein the outer ring is sleeved outside the inner ring, the steel balls are arranged between the outer ring and the inner ring, the steel balls are arranged in grooves on the outer side of the inner ring, the quantity of the grooves is two, the two grooves are adjacently arranged outside the inner ring in parallel, and a plane on which the groove stays forms an angle of 75DEG with the axis of the inner ring; and the outer side of the outer ring is provided with a positioning rod. According to the double-inclined-groove bearing, the outer side structure of the bearing inner ring is changed, so that not only is the movement way of the bearing outer ring changed, but also the loading capacity of the bearing is enhanced, the service life of the bearing is prolonged, and the application range of the bearing is enlarged.
Description
Technical field
The utility model relates to a kind of biserial valley road bearing, belongs to the mechanical part field.
Background technique
General common rolling bearing comprises inside and outside two circles, and the motion mode of existing common housing washer is and rotatablely moves, function singleness.And most of bearing is single raceway groove bearing, when using in some big machinery, often embodies the stress-bearing capability deficiency.
The model utility content
The technical problems to be solved in the utility model is to overcome existing defective, and a kind of biserial valley road bearing is provided, and changes the motion mode of bearing outer ring, strengthens simultaneously the stress-bearing capability of bearing.
In order to solve the problems of the technologies described above, the utility model provides following technological scheme:
A kind of biserial valley road bearing, comprise outer ring, inner ring and steel ball, outer ring sleeve is in the inner ring outside, be provided with steel ball between outer ring and inner ring, steel ball is arranged in the raceway groove in the inner ring outside, raceway groove is two, and is parallel and be adjacent to be arranged on the outside of inner ring, and raceway groove plane of living in and inner ring axis are 75 ° of angles; The arranged outside of outer ring has a positioning rod.
Further, also be provided with to fix and position the retainer of steel ball between outer ring and inner ring.
Further, positioning rod and forging outer ring are an integral body.
Further, the rod end of positioning rod is hollow-core construction.
A kind of biserial valley of the utility model road bearing has changed the outboard structure of bearing inner race, and the motion mode of bearing outer ring is changed, and has also strengthened the stress-bearing capability of bearing, has extended the working life of bearing, has enlarged the using scope of bearing.
Description of drawings
Accompanying drawing is used to provide further understanding of the present utility model, and consists of the part of specification, is used from explanation the utility model with embodiment one of the present utility model, does not consist of restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the structural representation of a kind of biserial valley of the utility model road bearing.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of biserial valley road bearing, comprise outer ring 1, inner ring 2 and steel ball 3, outer ring 1 is enclosed within inner ring 2 outsides, be provided with steel ball 3 between outer ring 1 and inner ring 2, steel ball 3 is arranged in the raceway groove in inner ring 2 outsides, and raceway groove is two, parallel and be adjacent to be arranged on the outside of inner ring 2, raceway groove plane of living in and inner ring 2 axis are 75 ° of angles; The arranged outside of outer ring 1 has a positioning rod 4, and forging with outer ring 1 is an integral body.
Also be provided with to fix and position the retainer 5 of steel ball 3 between outer ring and inner ring, with each steel ball 3 separately, and make it can not break away from raceway groove.
The rod end of positioning rod 4 is hollow-core construction, facilitates positioning rod 4 and miscellaneous part to be connected and fixed.
The design of double channel makes the stress-bearing capability of bearing increase exponentially, is applicable to the big machinery device.
Working principle: inner ring is arranged on the running shaft of miscellaneous part, the positioning rod of outer ring embeds in the locating slot that sets in advance, and drives the inner ring rotation by running shaft, in the time of the inner ring rotation, carry out along the reciprocally swinging of inner ring axis direction under the double action of valley road and positioning rod the outer ring.
A kind of biserial valley of the utility model road bearing has changed the outboard structure of bearing inner race, and the motion mode of bearing outer ring is changed, and has also strengthened the stress-bearing capability of bearing, has extended the working life of bearing, has enlarged the using scope of bearing.
It should be noted that at last: the above only is preferred embodiment of the present utility model, be not limited to the utility model, although with reference to previous embodiment, the utility model is had been described in detail, for a person skilled in the art, it still can be modified to the technological scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characteristics wherein is equal to replacement.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
