Abstract
The utility model is a detachable bearing of the three-point contact type clutch, which belongs to the technical field of detachable bearing of the clutch. The bearing is mainly used for solving problems of the two-point contact type clutch in the prior art such as limited bearing capability of the axial load, rapid loss of the lubricating grease, short life of the bearing. The utility model is characterized in that the bearing comprises an inner ring of the bearing, an outer ring of the bearing, steel balls, a retaining rack, a sealing ring, and lubricating grease; a left blocking edge and a right blocking edge are respectively formed on the left side and the right side of the groove; the curvature of the outer ring groove of the bearing is larger that the curvature of the steel ball, so that a contact point is formed; the inner ring of the bearing is a composite groove constructed by two sections of circular grooves having the curvature larger than the curvature of the steel ball, and symmetrical on both sides, so that two symmetrical contact points on both sides are formed. The utility model has features of huge axial bearing capability, relatively great self-lubricating performance, and long life, and is mainly used for detachable bearings of the three-point contact type clutch on vehicles of urban buses, trucks, business utility vehicles, automobiles, tractors, engineering vehicles or 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 3 contact-type clutch release bearings on waiting for bus that are 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 based on axially, 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 3 contact-type clutch release bearings of design, this bearing increases the bearing axial carrying capacity greatly, also can increase its radially bearing capacity, and have self lubricity preferably simultaneously, improve the working life of clutch release bearing.
Solution of the present utility model is: a kind of 3 contact-type clutch release bearings, it comprises bearing inner race, bearing outer ring, steel ball, retainer, seal ring and lubricating grease, on bearing inner race and bearing outer ring, be provided with the raceway groove that is used to hold steel ball, it is characterized in that: form left rib and right rib respectively in the left and right sides of described raceway groove; The bearing outer ring groove curvature forms a point of contact greater than steel ball curvature; The raceway groove of bearing inner race be by two sections curvature greater than the compound raceway groove that steel ball curvature and monosymmetric circular arc constitute, form two monosymmetric point of contact.
The compound raceway groove of bearing inner race described in the utility model technical solution, bearing outer ring raceway groove both sides are equipped with the depot fat chamfering.
The angle of two point of contact of the compound raceway groove of the bearing inner race described in the utility model technical solution and the steel ball line of centres is between 50 °-70 °.
The utility model is owing to the channel design with bearing outer ring becomes the circular arc of groove curvature greater than steel ball curvature, thereby at point of contact of the centre of raceway groove formation, because the channel design of bearing inner race is become by two sections curvature greater than steel ball curvature, and the compound raceway groove that monosymmetric circular arc constitutes, thereby on the shape circular arc of both sides, form the point of contact of two symmetries, so just form the bikini angle contacting, form lubricant film in the time of in working order easily, has good lubricating property, simultaneously can bear bigger axial alternating force, its bearing capacity is about 5/4 times of 2 contact clutches.The utility model is owing to be provided with back the fat chamfering on the both sides of bearing outer ring raceway groove, the compound raceway groove of bearing inner race, thereby more helps the lubricating grease formation of backflow and lubricant film fast.
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 compound raceway groove 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, engineering truck 3 contact-type clutch release bearings on waiting for bus.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1.3 contact-type clutch release bearings of the present utility model comprise bearing inner race 1, steel ball 2, bearing outer ring 3, retainer 4 and seal ring 5.Be provided with the raceway groove that is used to hold steel ball 2 on bearing inner race 1 and bearing outer ring 3, the left and right sides of raceway groove forms left rib and right rib respectively.Steel ball 2 is located between bearing inner race 1 and the bearing outer ring 3.Steel ball 2 is provided with compound raceway with bearing inner race 1 outer side surface and forms two point of contact 1-1, forms a point of contact 3-1 with circular arc curvature raceway groove on the bearing outer ring 3.The compound raceway groove of bearing inner race 1 and steel ball two point of contact 1-1 and steel ball 2 line of centres angles are between 50 ° ~ 70 °.Two point of contact of steel ball 2 and bearing inner race 1 raceway groove with bearing outer ring on a point of contact on the raceway groove is common forms at 3 and contact.Compound trench bottom on the bearing inner race 1 can store grease.Bearing inner race 1 compound raceway groove, bearing outer ring 3 raceway groove both sides are equipped with depot fat chamfering 1-2,3-2, have improved lubrication effect, improve bearing working life.
