Abstract
The utility model relates to a railway freight car bearing plucking cover dismantling machine, which is provided with at least three plucking claw axles in the longitudinal and symmetrical positions of a plucking cover body. The two ends of each plucking claw axle are respectively provided with a plucking claw and a plucking claw gear, wherein, the plucking claw gears of one plucking claw axle are driven by a plucking claw motor driving device, and the plucking claw gears and the synchronous gear in a shell mesh and drive the plucking claw gears on other plucking claw axles. Additionally, the plucking body is provided with a plucking cover axle in the coaxial position, the two ends of the plucking cover axle are respectively connected with a withdrawing cover pressing lid and a plucking cover motor driving device, the plucking cover motor driving device is connected with the plucking cover body through a connecting seat. The utility model adopts a planar transferring mechanism and fully makes use of the inner space of the bearing, which is safe and reliable, causes no harm to the sealant cover, and automatizes the processes of plucking cover and withdrawing cover.
Description
Technical field
The utility model relates to a kind of goods train vehicle repair apparatus.
Background technology
In the goods train vehicle maintenance process to lorry bearing detection since the particularity of its structure must adopt specialized equipment to decompose and could clean maintenance.The existing bearing disassembler is to drive claw by the claw oil cylinder to do by pulling out the cover oil cylinder seal closure to be pulled up in the seal closure of garden arc motion insertion bearing around its connecting rod pawl that links to each other with the claw oil cylinder again.This cover disassembler that pulls out is owing to claw need be done garden arc motion, need bigger motion space, and the space of the domestic labyrinth type novel seal cover of progressively applying is less at present, therefore, existing disassembler can't use, if use by force then can cause the damage of seal closure, or make the seal closure distortion.Unordered placement behind the seal closure of in addition this disassembler decomposition bearing has only by artificial go-on-go, thereby has increased artificial and labour intensity.
Of the present utility model open
The purpose of this utility model is in order to provide a kind of employing plane to change formula mechanism over to, has made full use of the inner space, safe and reliable of freight car bearing, and has not damaged seal closure, pulls out cover, moves back the automatable railway truck bearing of cover and pull out the cover disassembler.
The purpose of this utility model can realize by following measure:
It is in the radial symmetry position of pulling out cover body at least three pusher dog axles to be housed that a kind of railway truck bearing pulls out the cover disassembler, at the two ends of each pusher dog axle pusher dog and pusher dog gear are housed respectively, pusher dog gear on one of them pusher dog axle is driven by the pusher dog Power Drive Unit, is driven the pusher dog gear of all the other pusher dog axles again by the engagement of the synchronizer gear on this pusher dog gear and the housing; Be equipped with in addition and pull out the cover axle, be connected with respectively at the two ends of pulling out the cover axle and move back the cover gland and pull out the cover Power Drive Unit at the coaxial position that pulls out cover body, pull out the cover Power Drive Unit by Connection Block with pull out cover body and link to each other.
The utility model has following advantage compared to existing technology:
1, pusher dog of the present utility model is to adopt the plane to change formula mechanism over to, be the bearing felt cover radially change seal closure over to, the required axial space of its operation is very little, has made full use of the inner space of freight car bearing, thereby the decomposition of applicable new, old seal closure.
2, comformability of the present utility model is strong, thereby safe and reliable, does not damage seal closure.
3, of the present utility modelly pull out cover, move back cover and can realize automation, can guarantee to decompose quality, alleviate labor intensity of operating personnel.

Embodiment of the present utility model
The utility model is also incited somebody to action in conjunction with the accompanying drawings, and embodiment is described in further detail:
With reference to Fig. 1, it is in the radial symmetry position of pulling out cover body 6 four pusher dog axles 17 to be housed that a kind of railway truck bearing pulls out the cover disassembler, at the two ends of each pusher dog axle 17 pusher dog 4 and pusher dog gear 8 are housed respectively, pusher dog gear 8 on one of them pusher dog axle 17 is driven by pusher dog cylinder 7, is driven the pusher dog gear 8 of all the other pusher dog axles 17 again by this pusher dog gear 8 and synchronizer gear (9) engagement on the housing 13; Axle head at pusher dog axle 17 also is provided with spring 10; Be equipped with in addition and pull out cover axle 12, be connected with respectively at the two ends of pulling out cover axle 12 and move back cover gland 5 and pull out cover oil cylinder 11 at the coaxial position that pulls out cover body 6, pull out cover oil cylinder 11 by Connection Block 13 with pull out cover body 6 and link to each other.Outside pulling out cover body 6, also be with in addition and move back cover baffle ring 3; Also be connected with pulley 16 on the cover body 6 pulling out, be connected with displacement cylinder 14 on the pulley 16, pulley 16 can slide on the guide rail on the frame 15.
Principle of work of the present utility model be when bearing 1 roll into pull out cover position after, 14 actions of displacement cylinder make pulls out the reach of cover mechanism, make and pull out cover body 6 front ends and be close to bearing 1 end face, 7 actions of pusher dog cylinder change in bearing 1 seal closure 2 pusher dog 4 over to, pulling out the action of cover oil cylinder 11 this moment makes and moves back cover gland 5 and return, driving pusher dog 4 leaves behind seal closure 2, this moment, bearing structure was released bearing 1, pulling out the action of cover oil cylinder 11 then makes and moves back cover gland 5 and return, pusher dog 4 is also return under the effect of spring 10 simultaneously, 7 actions of pusher dog cylinder are regained pusher dog 4, displacement cylinder 14 is return, while seal closure 2 falls back on cover baffle ring 3 places comes off seal closure 2 automatically, by falling outside the passage discharge machine, pulls out cover and decomposes end.
