Specific embodiment
This utility model is described below based on embodiment, but this utility model is not restricted to these enforcements Example.
Outrigger shaft location structure in the application can be used for the positioning of all outrigger shafts for bearing load, can reduce mill Damage, increase the service life of total.
For convenience of description, by taking the outrigger shaft of motor as an example the outrigger shaft location structure in the application is said below It is bright.
As Figure 2-3, motor 10 has outrigger shaft 20, and the one end of the outrigger shaft 20 is connected with the inside of motor 10, in addition One end is free end.In the application, the free end of outrigger shaft 20 is connected with fixing component 40.The fixing component 40 can be external The free end for stretching axle 20 is positioned and fixed.The fixing component 40 for example can be casing of drive mechanism etc..Described Location division 401 is provided with fixing component 40, the location division 401 can be the structures such as groove, hole or flange, shown in Fig. 3 In the embodiment for going out, the location division 401 is groove.The freedom for accommodating outrigger shaft 20 is provided with the location division 401 The space at end.
Preferably, adjustment structure 402 is provided with the location division 401, the adjustment structure 402 is located at fixing component Between 40 and the free end of outrigger shaft 20, when load is loaded with outrigger shaft 20, the adjustment structure 402 can adjust itself Attitude, is automatically positioned.
Specifically, as Figure 2-3, the location division 401 is sphere hole, and the adjustment structure 402 is ball bearing.It is described Ball bearing is preferably oil-containing ball bearing, is easy to the lubrication of bearing.Specifically, the surface of oil-containing ball bearing and the free end of outrigger shaft 20 Contact area can automatically form protective lubricating oil film in load running, and oil film can be returned automatically when load stops In being drawn onto the spherical Bearing inner hole shape structure of oil-containing.The protectiveness lubricating oil film can also pass through people after normal consumption loss The modes such as work filling are supplemented, to realize permanent lubrication protection effect.
Preferably, the aperture Φ d of the sphere hole match with the external diameter of ball bearing, and both are cooperatively formed by small―gap suture Face contacts.The cylindrical hole 403 through the centre of sphere is offered on the ball bearing 402, for coordinating with the free end of outrigger shaft 20. The cylindrical hole 403 can be through hole, or blind hole, as long as can be formed with the free end of outrigger shaft 20 effectively coordinate i.e. Can.
In order to be fixed to adjusting structure 402, in the free end place side with outrigger shaft 20 of the adjustment structure 402 Contrary side is provided with Fastener 50, correspondingly, is provided with for accommodating in the side of the close motor 10 of the sphere hole The Fastener space 501 of Fastener 50, the Fastener space 501 is preferably cylindrical hole, and one end of the cylindrical hole is open end, Other end is connected with the end of the side of close motor 10 of sphere hole, and the external diameter in the poroid Fastener space of the cylinder is Φ a.The external diameter of the Fastener 50 is more than the outside dimension for adjusting structure 402, the external diameter Φ a in the Fastener space 501 More than the external diameter of Fastener 50.As illustrated in figures 4-5, it is preferable that the Fastener 50 is including the bail wire 502 being connected with each other and admittedly Determine pawl 503, the fixed claw 503 is provided with multiple, is distributed on the radially inner side of the bail wire 502.The fixed claw 503 is excellent Elastic construction piece is elected as, in radial directions with certain elasticity.
During assembling, Fastener 50 of the excircle dimension less than Φ a is pressed into behind the Fastener space 501, by its bail wire 502 realize fixed effect with the interference fit in the hole in Fastener space 501.It is distributed in the fixed claw of the radially inner side of bail wire 502 503 surfaces for being pressed on ball bearing 402, the effect of pressing is while make ball bearing 402 and sphere internal surface of hole and fixed claw 503 Inner surface forms pretension.When external force suffered by ball bearing 402 is more than aforementioned pretightning force, ball bearing 402 just along the rotation of its centre of sphere with Its central hole location is adjusted, so as to adjust the stressing conditions of location structure.
As shown in Fig. 2 in a preferred embodiment, worm structure 70, the snail are provided with the outrigger shaft 20 Bar structure 70 can coordinate with gear 60, so as to form load on the outrigger shaft 20.When gear 60 starts to nibble with worm screw 70 After conjunction, the active force on V directions suffered by worm screw 70 is transferred to motor outrigger shaft 20, and motor outrigger shaft 20 passes through oily globule axle The Self-aligning ability held realizes automatic positioning function.Specifically, in the circle of ball bearing 402 after the motor outrigger shaft stress for assembling In post holes 403 along V directions and its backswing when, the inner surface of the cylindrical hole 403 of ball bearing 402 is outer with motor outrigger shaft 20 Point/linear contact lay is formed between surface, when the point/linear contact lay active force is more than the outer surface of ball bearing 402 and the interior table of sphere hole 401 During surface pretightning force between face, ball bearing 402 is rotated under the point/linear contact lay active force around its centre of sphere.When 402 turns of ball bearing Move when face contact position is formed between its cylindrical hole 403 and motor outrigger shaft 20, ball bearing 402 is because of its institute of interior cylindrical hole 403 Balance being reached by contact force and pretightning force suffered by outer surface and not being rotated further by, motor outrigger shaft 20 also completes therewith corresponding solid It is fixed, so as to reach the effect being automatically positioned.
In the application, carrying can be transferred to ball bearing 402, ball axle by motor outrigger shaft 20 after applied load is born 402 relative positions for utilizing the regulation of mental activities positioning action of itself, its interior cylindrical hole 403 of real-time adjustment and motor outrigger shaft 20 are held, with Maximum area ground contact between the two is realized, makes contact pressure reach minimum, by reducing mutually abrasion to reach increase structure The purpose in life-span;Due to the Self-aligning ability of ball bearing so that there is the situation of deviation in element precision reduction, assembling process Under, product overall precision can still keep preferable level after assembling, and performance is also unaffected.
