Abstract
The utility model relates to an oval channel contact type clutch separation bearing, which belongs to the technical field of a clutch separation bearing and mainly solves the problems that in the existing two-point contact type clutch separation bearing, the limited axial load carrying capability is limited, the lubricating grease loss is fast, and the service life of the bearing is short. The utility model is mainly characterized in that the oval channel contact type clutch separation bearing comprises an inner ring, an outer ring, a steel ball, a retainer, a sealing ring and lubricating grease, wherein a plurality of steel balls are distributed between the inner ring and the outer ring of the bearing, the inner wall of the outer ring is provided with an oval channel, a left baffle edge and a right baffle edge are formed at the left side and the right side of the oval channel, the oval cross sections of the oval channel of the outer ring and the inner ring are in contact with the steel balls, and four contact points with the two symmetrical sides are formed. The oval channel contact type clutch separation bearing has the characteristics that the axial carrying capability is high, the self lubrication performance is good, and the service life is long. The oval channel contact type clutch separation bearing is mainly used on vehicles such as urban buses, trucks, commercial vehicles, automobiles, tractors, engineering vehicles and the like.
Description
Technical field
The utility model belongs to the clutch release bearing technical field, is specifically related to a kind of city bus, truck, commercial car, automobile, tractor, engineering truck elliptic channel contact-type clutch release bearing on waiting for bus that is applicable to.
Background technique
According to market survey, the clutch release bearing that generally adopts is inner ring, outer ring, steel ball, retainer, seal ring, the grease composition by bearing at present.Steel ball is located between the Internal and external cycle of bearing, respectively is provided with the circular arc of a curvature greater than the bearing sectional curvature of steel ball on Internal and external cycle, and steel ball and raceway groove are tangential on 2 points.The bearing capacity of this bearing axial load is limited, and lubricating grease runs off very fast, and the working life of bearing is on the low side.Along with the high speed development of automotive industry, more and more higher to the clutch release bearing requirement, many vehicles with specific (special) requirements are had higher requirement to clutch release bearing, particularly the operating mode of the frequent clutch of city bus.Its requirement can be born with axially not main, radially is that the stress alternation of assisting is impacted bearing rotating speed height, good stability; Require bearing to have good self lubricity, sealing, anti-dust, the intrusion of materials such as muddy water simultaneously.Thereby present bearing can not satisfy the specific (special) requirements of these vehicles.
Summary of the invention
The purpose of this utility model is a kind of elliptic channel contact-type clutch release bearing of design, this bearing steel ball raceway groove sectional shape is oval, can obviously improve the stressing conditions of steel ball and raceway groove, improved bearing capacity, trench edges can not produce under the effect of steel ball and peel off simultaneously, therefore designing elliptic channel and be the key parameter of angle contacting clutch shaft bearing structure sees in the formula, the outer fissure coefficient of curvature is fe, interior raceway groove coefficient of curvature is fi, steel ball size d wrapping angle β, major axis a, minor axis b increases the bearing axial carrying capacity greatly, also can increase its radially bearing capacity.And have self lubricity preferably simultaneously, improved the working life of clutch release bearing.For achieving the above object, its elliptic parameter is:
Technical solution of the present utility model is: a kind of elliptic channel contact-type clutch release bearing, it comprises bearing inner race, bearing outer ring, steel ball, retainer, seal ring and lubricating grease, some steel balls distribute between bearing inner race and bearing outer ring, it is characterized in that: be provided for holding the elliptic channel of steel ball at the inwall of bearing outer ring, form shelves limit, a left side and right shelves limit in the left and right sides of elliptic channel respectively; The oval cross section of this bearing outer ring, inner ring elliptic channel contacts with steel ball, forms four monosymmetric point of contact.
Bearing outer ring elliptic channel described in the utility model both sides are provided with the depot fat chamfering.
The angle of two point of contact of the elliptic channel of bearing inner race described in the utility model, bearing outer ring and the steel ball line of centres is between 50 °～70 °.
The beneficial effects of the utility model:
1, changes the sectional shape of inner ring, steel ball and the outer ring of bearing, solved the situation of bearing from structure;
2, by the oil film of elliptic channel can bear bearing axially be main, be the change impacts of assisting radially, guaranteed the self lubricity of bearing simultaneously, bearing is prolonged working life;
3, structurally possessed the aligning function, realized the raising of clutch release bearing combination property.
The utility model is mainly used in city bus, truck, commercial car, automobile, tractor, the engineering truck elliptic channel contact-type clutch release bearing on waiting for bus.
