Description
Technical field
The utility model relates to technical field of bearings, specifically sliding bearing, also referred to as axle sleeve.
Background technique
As shown in Figure 1, for the axle sleeve of routine, external diameter is all cylindrical body.In use exist between external diameter and housing bore and have skidding.Especially for the axle sleeve that wall thickness is smaller, even if it is very large with the magnitude of interference of housing bore, also have skidding appearance.The appearance of skidding, the serious precision reducing axle sleeve, make axle sleeve running noise become large, temperature raises, and there will be axle and axle sleeve stuck phenomenon, thus affect the normal work of whole machine time serious.
Summary of the invention
For overcoming the defect that prior art exists, the purpose of this utility model is to provide a kind of axle sleeve with anti-skidding boss, has location and installation reliable, prevents from skidding, long service life and the reliable and stable advantage that operates.
For achieving the above object, the utility model provides following technological scheme: a kind of axle sleeve with anti-skidding boss, include cylindric sleeve body, it is characterized in that: the axial one end of described sleeve body is provided with the anti-skidding boss of radially outward projection, and anti-skidding boss is higher than the outer peripheral surface of described sleeve body.
By adopting technique scheme, the outer peripheral surface of sleeve body forms anti-skidding boss, as long as then arrange corresponding groove in housing, the anti-skidding boss of the axial one end of sleeve body embeds in groove, lock point is formed between sleeve body and housing, effective realization prevents axle sleeve rotational slippage, and anti-skidding boss is positioned at the axial one end of axle sleeve, easy to assembly.
The utility model is set to further: described anti-skidding boss is the sleeve body sidewall radially arcuate configuration that arches upward of side, and corresponding described sleeve body endoporus side forms the groove corresponding with anti-skidding boss.
By adopting technique scheme, being processed to form of anti-skidding boss is convenient and simple, and the thickness of sleeve body can not increase, and avoids the formation of anti-skidding boss to affect the mechanical property of sleeve body entirety, and reduces cost of material.
The utility model is set to further: described anti-skidding boss is axial inner ends to the punching press flange of axial outer end radial protrusion gradually, and corresponding described sleeve body endoporus side forms the groove corresponding with anti-skidding boss.
By adopting technique scheme, anti-skidding boss arches upward and adopts the punching press flange of punching press formation, formed by the distortion of metal, being processed to form of anti-skidding boss is convenient and simple, and anti-skidding boss is punching press flange, and punching press turnup structure feature is the shape that axial one end is lifted gradually to the other end, firm position is reliable, and the weight of axle sleeve can not be increased, reduce cost of material, improve axle sleeve run stability.
The utility model is set to further: the radial cross-sectional shape of described anti-skidding boss is circular arc.
By adopting technique scheme, under anti-skidding boss shape, structural strength is large, and location is reliable, long service life.
The utility model is set to further: described sleeve body is set in by steel cylindrical matrix that copper alloy bushing is external to be formed, described anti-skidding projection comprises and is positioned at first of steel cylindrical matrix and arches upward and be positioned at second on copper alloy bushing body and arch upward, and on copper alloy bushing body, second arches upward and be flush-mounted in first of steel cylindrical matrix arches upward.
By adopting technique scheme, steel cylindrical matrix is set in the external formation of copper alloy bushing, structural strength is high, bearing capacity is large, wear resistance is good and reduce the friction of axle sleeve and axle, improve usability and the life-span of axle sleeve, and the design of arching upward, make steel cylindrical matrix and copper alloy bushing body in conjunction with solid and reliable.
Below in conjunction with accompanying drawing, the utility model is further described.

Embodiment
See accompanying drawing 2 to accompanying drawing 4, a kind of axle sleeve with anti-skidding boss disclosed in the utility model, include cylindric sleeve body 1, described axial one end of sleeve body 1 is provided with the anti-skidding boss 11 of radially outward projection, and anti-skidding boss 11 is higher than the outer peripheral surface 12 of described sleeve body 1.The outer peripheral surface of sleeve body 1 is formed anti-skidding boss 11, as long as then arrange corresponding groove in housing, the anti-skidding boss 11 of the axial one end of sleeve body 1 embeds in groove, lock point is formed between sleeve body and housing, effective realization prevents axle sleeve rotational slippage, and anti-skidding boss is positioned at the axial one end of axle sleeve, easy to assembly.
In this specific embodiment, described anti-skidding boss 11 is the sleeve body 1 sidewall radially arcuate configuration that arches upward of side, and corresponding described sleeve body 1 endoporus side forms the groove 13 corresponding with anti-skidding boss 11.Being processed to form of anti-skidding boss is convenient and simple, and the thickness of sleeve body can not increase, and avoids the formation of anti-skidding boss to affect the mechanical property of sleeve body entirety, and reduces cost of material.
Further, described anti-skidding boss 11 is axial inner ends 111 to the punching press flange of axial outer end 112 radial protrusion gradually, and corresponding described sleeve body 1 endoporus side blow swaging becomes the groove 13 corresponding with anti-skidding boss 11.Anti-skidding boss arches upward and adopts the punching press flange of punching press formation, formed by the distortion of metal, being processed to form of anti-skidding boss is convenient and simple, anti-skidding boss is punching press flange, punching press turnup structure feature is the shape that axial one end is lifted gradually to the other end, and firm position is reliable, and can not increase the weight of axle sleeve, reduce cost of material, improve axle sleeve run stability.And the radial cross-sectional shape of described anti-skidding boss 11 is circular arc.Anti-skidding boss 11 is under circular shape, and structural strength is large, good stability, and location is reliable, long service life.
In this specific embodiment, described sleeve body 1 is set in outside copper alloy bushing body 15 by steel cylindrical matrix 14 and is formed, described anti-skidding protruding 11 comprise and are positioned at first of steel cylindrical matrix 14 and arch upward 114 and be positioned at second on copper alloy bushing body 15 and arch upward 115, and on copper alloy bushing body 15, second arches upward and 115 be flush-mounted in first of steel cylindrical matrix 14 and arch upward in 114.Steel cylindrical matrix is set in the external formation of copper alloy bushing, structural strength is high, bearing capacity is large, wear resistance is good and reduce the friction of axle sleeve and axle, improve usability and the life-span of axle sleeve, and the design of arching upward, make steel cylindrical matrix and copper alloy bushing body in conjunction with solid and reliable.
