Abstract
The utility model discloses a four-contact-point self-aligning pull type clutch release bearing unit, which belongs to the technical field of clutch release bearings and mainly solves the problems that an existing self-aligning pull type clutch release bearing unit is poorer in axial load bearing capacity, and an engineering plastic retainer is easy to fail. The four-contact-point self-aligning pull type clutch release bearing unit is characterized by comprising a release sleeve, a bearing inner ring, a bearing outer ring and a steel ball, wherein channels are arranged on the inner wall of the bearing outer ring and the outer wall of the bearing inner ring, a left flange and a right flange are respectively formed on the left side and the right side of the channel on the inner wall of the bearing outer ring, each of the channels is a combined channel consisting of two circular arcs, the curvature of each circular arc is larger than that of the steel ball, two sides of each circular arc are symmetric, and the two circular arcs of each channel form four contact points symmetric on two sides. The four-contact-point self-aligning pull type clutch release bearing unit has the advantages that the release bearing unit is fine in lubricating performance and can bear larger axial alternating force, and a retainer is difficult to fail. The four-contact-point self-aligning pull type clutch release bearing unit is mainly used in heavy-duty vehicles, engineering trucks, buses, passenger vehicles and commercial vehicles.
Description
Technical field
The utility model belongs to the clutch release bearing technical field, is specifically related to a kind ofly be applicable to that 4 contacts on heavy goods vehicles, engineering truck, bus and passenger car, the commercial car are from aligning pull type clutch release bearing unit.
Background technique
Be mounted in the release bearing on the gearbox I outer shaft sleeve pipe from aligning pull type clutch release bearing unit.At work, the power transmission moment of torsion is big, and the axial separation force that rotating speed height, release bearing bear is bigger.Existing self-aligning pull type clutch release bearing adopts the two point form angle contacting, does not in use reach ideal effect, produces a series of early failure phenomenas.Mainly be that under the high temperature and high speed operating mode, lubricating grease runs off fast because of the axial bearing load poor-performing of release bearing, temperature sharply raises, and causes engineering plastics cage to lose efficacy.
Summary of the invention
The purpose of this utility model be exactly provide at above-mentioned deficiency a kind of have greasy property good, can bear at 4 that bigger axial alternating force and retainer be difficult for losing efficacy and contact from aligning pull type clutch release bearing unit.
Solution solution of the present utility model is: a kind of 4 contacts are from aligning pull type clutch release bearing unit, it comprises release sleeve and is positioned at bearing inner race on the periphery wall of release sleeve left side, there is bearing outer ring outside at bearing inner race, some steel balls distribute between bearing inner race and bearing outer ring, inwall at bearing outer ring, the outer wall of bearing inner race is provided for holding the raceway groove of steel ball, the raceway groove left and right sides at the inwall of bearing outer ring forms left rib and right rib respectively, it is characterized in that: described bearing outer ring, the raceway groove of bearing inner race is greater than steel ball curvature by two sections curvature, and the compound raceway groove that monosymmetric circular arc constitutes forms four monosymmetric point of contact.
The compound trench bottom of bearing inner race described in the utility model technical solution forms groove, and the both sides of compound raceway groove are provided with back the fat chamfering; The compound trench bottom of bearing outer ring forms groove, and the both sides of compound raceway groove are provided with back the fat chamfering.
The hem width that the compound raceway groove of bearing inner race described in the utility model technical solution returns the fat chamfering is 0.6-0.8mm, is 0.2-0.5mm deeply, and angle is 25-30 °; The hem width that the compound raceway groove of bearing outer ring returns the fat chamfering is 0.6-0.8mm, is 0.2-0.5mm deeply, and angle is 25-30 °.
Be provided with the refractory metal retainer of locking ball between bearing inner race described in the utility model technical solution and the bearing outer ring.
The raceway groove of the utility model bearing outer ring, bearing inner race is owing to all adopt the compound raceway groove that is made of greater than steel ball curvature and monosymmetric circular arc two sections curvature, thereby two monosymmetric point of contact of each self-forming, so just form the four-point angle contacting, in working order down, form lubricant film easily, have good lubricating property, can bear bigger axial alternating force simultaneously.The utility model is owing to form groove in bearing outer ring, bearing inner race trench bottom, and the both sides of raceway groove are provided with back the fat chamfering, thereby more helps the formation of quick backflow of lubricating grease and lubricant film.The utility model is owing to be provided with the refractory metal retainer of locking ball between bearing inner race and the bearing outer ring, thereby can thoroughly solve the problem that engineering plastics cage lost efficacy.The utlity model has the characteristics that greasy property is good, can bear bigger axial alternating force and the difficult inefficacy of retainer.The utility model is mainly used in 4 contacts on heavy goods vehicles, engineering truck, bus and passenger car, the commercial car from aligning pull type clutch release bearing unit.
