Description

A kind of super-huge double-row conical pivoting support of low friction
Technical field
The invention belongs to pivoting support technical fields, and in particular to a kind of super-huge double-row conical revolution branch of low friction It holds.
Background technique
Pivoting support is called turntable bearing, using very extensively in real industry, is known as " joint of machine ", is Need to make opposite rotary motion between two articles, but need to bear simultaneously axial force, radial force, tilting moment machinery necessary to weight Want transmission parts.With the rapid development of machinery industry, pivoting support is in ship equipment, engineering machinery, light industry and machinery, metallurgical machine The industries such as tool, medical machinery, industrial machinery are widely used.
When in use due to existing super-huge double-row conical pivoting support, the active force of receiving is larger, inside Retainer and inner ring or outer ring contact surface it is big, cause inner ring, outer ring and retainer contact site serious wear, affect revolution The normal use of bearing, effect are undesirable.
Summary of the invention
In order to solve the above-mentioned technical problem the present invention, provides a kind of super-huge double-row conical pivoting support of low friction, The position that retainer is contacted with pivoting support Internal and external cycle is designed as pit shape structure, in use, meeting exists due to the appearance of pit Retainer and Internal and external cycle contact site form oil film, greatly reduce the probability that the position is worn, are conducive to extend revolution The service life of bearing.
The technical scheme adopted by the invention is that: a kind of super-huge double-row conical pivoting support of low friction, including it is interior Circle, outer ring, taper roller and retainer keep the position being placed between inner ring and outer ring, and the quantity of retainer is two, protect Holding frame is tapered annular structure, and the thickness direction of retainer offers multiple around the equally distributed bellmouth in retainer center, guarantor The one end for holding frame is connected with the lug boss that thickness is greater than retainer wall thickness, the side of lug boss and the platform of inner ring inner side end Rank is in contact, and the side surface that lug boss is in contact with step is equipped with multiple around the equally distributed V-type groove in retainer center.
The minimum point of the V-type groove is 2.5mm at a distance from lug boss surface.
The angle of the V-type groove is 170 °.
The inner ring includes the first inner ring and the second inner ring, and the first inner ring is connected with the second inner ring by connecting bolt.
The quantity of the taper roller and the quantity of bellmouth are equal, and each taper roller correspondence is mounted on bellmouth On position, the outer circumference face of taper roller is in contact with the raceway of the raceway of outer ring, inner ring respectively.
When work, the ledge surface on inner ring is close in the lug boss side on retainer, due to retainer lug boss surface Equipped with multiple V-type grooves, lubricant grease can be added in V-type groove at work, so that in the lug boss surface and inner ring, outer One layer of oil film is formed between circle, the frictional force generated by oil film come retainer when reducing work and raceway face can extend guarantor Hold frame, inner ring, outer ring service life, and guarantee the operation is stable of pivoting support.
One end of the retainer be connected with thickness be greater than retainer wall thickness lug boss, the side of lug boss with it is interior The step of circle inner side end is in contact, and the side surface that lug boss is in contact with step is equipped with multiple uniform around retainer center The V-type groove of distribution；The purpose being arranged in this way is: lug boss at work, is in contact with inner ring, therefore, thickness direction ruler The very little wall thickness greater than retainer also can normally be carried out using V-type is recessed in the case where lug boss is by certain abrasion Slot can make the contact surface between lug boss and inner ring reduce, and lubricant grease can be added in V-type groove, so that When pivoting support works, oil film is formed on contact surface, is reduced the frictional resistance between retainer and inner ring, is made pivoting support work Work is stablized, and the service life of pivoting support is extended.
The invention has the benefit that the configuration of the present invention is simple, design are reasonable, easy to use, by retainer and revolution branch The position for holding Internal and external cycle contact is designed as pit shape structure, in use, can be connect in retainer and Internal and external cycle due to the appearance of pit Contact portion position forms oil film, greatly reduces the probability that the position is worn, is conducive to extend the service life of pivoting support.

Specific embodiment
A specific embodiment of the invention is described in further detail below in conjunction with attached drawing.
As shown, a kind of super-huge double-row conical pivoting support of low friction, including inner ring, outer ring 1, taper roller 4 and retainer 5, retainer 5 is placed in the position between inner ring and outer ring 1, and the quantity of retainer 5 is two, and retainer 5 is taper Cyclic structure, the thickness direction of retainer 5 offer multiple around the equally distributed bellmouth 503 in 5 center of retainer, retainer 5 One end be connected with the lug boss 501 that thickness is greater than 5 wall thickness of retainer, the side of lug boss 501 and inner ring inner side end Step be in contact, and the side surface that is in contact with step of lug boss 501 be equipped with it is multiple equally distributed around 5 center of retainer V-type groove 502, wherein the minimum point of V-type groove 502 is 2.5mm, the folder of V-type groove 502 at a distance from 501 surface of lug boss Angle is 170 °, and the depth of 2.5mm and 170 ° of angle can guarantee that grease is stored in the V-type groove 502, and in revolution branch When holding work, under external force, grease is spread along two sides of angle to two sides, finally in retainer 5 and adjacent rolling Oil film is formed between road, can reduce retainer 5 and the frictional resistance of adjacent raceway at work, reduces the abrasion of retainer 5.
The inner ring includes the first inner ring 2 and the second inner ring 3, and the first inner ring 2 passes through connection bolt phase with the second inner ring 3 Even.
The quantity of the taper roller 4 is equal with the quantity of bellmouth 503, and the correspondence of each taper roller 4 is mounted on cone On the position in shape hole 503, the outer circumference face of taper roller 4 is in contact with the raceway of the raceway of outer ring 1, inner ring respectively.
When work, the ledge surface on inner ring is close in 501 side of lug boss on retainer 5, due to 5 lug boss of retainer 501 surfaces are equipped with multiple V-type grooves 502, lubricant grease can be added in V-type groove 502 at work, so that in the lug boss One layer of oil film is formed between 501 surfaces and inner ring, outer ring 1, is generated by oil film come retainer 5 when reducing work and raceway face Frictional force, can extend retainer 5, inner ring, outer ring 1 service life, and guarantee the operation is stable of pivoting support.
