Improve working efficiency.
Utility model content
In view of this, providing a kind of lubrication disassembly type cone the purpose of the utility model is to overcome defect in the prior art
Gear shaft can easily and efficiently dismantle the bearing inner race being interference fitted on axis, and not damage components, bearing and biography
Moving axis lowers assembly and maintenance cost significantly, improves working efficiency.
The lubrication disassembly type bevel gear shaft of the utility model, including transmission shaft, is shaped in the end part of driving shaft
Bevel gear and bearing removal component for pushing bearing of the housing on transmission shaft；The bearing removal component includes along same
Axis is set to the centre bore on the bevel gear outer end face, is slidingly sealed the sliding block being matched in the centre bore, passes through screw thread
Pushing block with centre bore cooperation for pushing sliding block to slide is set to the strip groove of transmission shaft outer circle and the connection centre bore,
And it is connected to the sliding block and passes through the baffle that the strip groove is stretched out outside transmission shaft；The sliding block be equipped with axially through
Oil filler point and plug for blocking the oil filler point；Centre bore is counter sink, and major diameter section has internal screw thread, path
Section is the unthreaded hole for cooperating with sliding block, and pushing block head has external screw thread, and bar portion is polished rod.
Further, the sliding block outer circle is equipped with annular groove, is equipped with sealing ring in annular groove；
Further, the baffle has multiple along sliding block is circumferentially distributed, and the strip groove and baffle have been arranged in a one-to-one correspondence more
It is a；
Further, the bevel gear inner face is formed with the annular groove for accommodating the baffle；
Further, the sliding block outer circle is equipped with the card slot for being clamped the baffle；The baffle is sector structure.
The beneficial effects of the utility model are: a kind of lubrication disassembly type bevel gear shaft provided by the utility model, the cone tooth
Wheel shaft can carry out rotating support by bearing, and bearing is usually resisted against the inner face of bevel gear, can be with when needing to dismantle bearing
Plug is extracted, lubricating oil is injected into centre bore by oil filler point, then rotating bevel gear axis, lubricating oil is made to pass through strip groove stream
To between the inner ring and transmission shaft of bearing, then oil filler point is blocked using plug, rotates pushing block, pushing block will push sliding block and gear
Piece slides axially together, and baffle pushes bearing to move axially along transmission shaft, so that the disassembly of bearing is carried out, the utility model benefit
With baffle transmitting thrust, is conducive to uniformly apply axial thrust to bearing inner race, avoids blocking between bearing and transmission shaft
Extremely.Can disassembly bearing inner race easily and fast, and do not damage components, bearing and transmission shaft, lower assembly and dimension significantly
Accomplish this, improves working efficiency.
Detailed description of the invention
The utility model is further described with reference to the accompanying drawings and examples:
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the distribution schematic diagram of the baffle of the utility model.
Specific embodiment
Fig. 1 is the structural schematic diagram of the utility model, as shown, 7 axis of detachable bevel gear in the present embodiment, packet
It includes transmission shaft 5, be shaped in the bevel gear 7 of 5 end of transmission shaft and for pushing bearing of the housing on transmission shaft 5
6 bearing 6 dismantles component；It includes along coaxial arrangement in the centre bore on 7 outer end face of bevel gear that the bearing 6, which dismantles component,
1, it is slidingly sealed the sliding block 2 being matched in the centre bore 1, is cooperated by screw thread and centre bore 1 for pushing sliding block 2 to slide
(centre bore 1 is counter sink to pushing block 9, and major diameter section has internal screw thread, and path is the unthreaded hole for cooperating with sliding block 2, pushing block head
With external screw thread, bar portion is polished rod), it is set to the strip groove 4 of 5 outer circle of transmission shaft and the connection centre bore 1, and connection
In the sliding block 2 and pass through the baffle 3 outside the strip groove 4 stretching transmission shaft 5；The sliding block 2 be equipped with axially through
Oil filler point 8 and plug for blocking the oil filler point 8；7 axis of bevel gear can carry out rotating support, bearing 6 by bearing 6
