Description
Technical field
This utility model relates to automatic transmission reconstruction technique field, particularly relates to a kind of automatic transmission and remanufactures by left half axle flange bearing installation tool.
Background technology
Left half axle is parts of automatic transmission, and there is flange one end of left half axle by bearings.Variator rebuilding course needs be installed to flange bearing between the axis hole of flange and left half axle realize being rotationally connected with on one end of left half axle flange, and during bearing is installed, is merely able to the one end away from separation from left half axle and loads onto bearing.Existing installation left half axle flange bearing mode be with hammer along bearing circumference conversion beating position mode carry out driving bearing moving axially along left half axle, due to the reason that the thickness of bearing is less and is interfered by semiaxis, it is inconvenient for when making installation bearing and installation rate is slow, and the mode that this local is beaten is easily caused bearing surface damage.
Utility model content
This utility model provides a kind of automatic transmission that can be installed between left half axle and flange by bearing easily and remanufactures by left half axle flange bearing installation tool, solve during automatic transmission remanufactures, bearing is installed to left half axle get on pivot flange time inconvenience problem.
More than technical problem is that and solved by following technical proposal: a kind of automatic transmission remanufactures by left half axle flange bearing installation tool, it is characterized in that, including push rod, one end of described push rod is provided with percussion section, the diameter of described percussion section is less than the diameter of the axis hole for installing described bearing of described flange, be provided with in described push rod the end face of through described percussion section and extend along push rod length direction dodge hole for what described left half axle inserted, described in dodge the diameter in the hole overall diameter less than the inner ring of described bearing.During use, first make left half axle penetrate flange in the axis hole installing bearing, then bearing holder (housing, cover) is set to the position that left half axle up to can not promote by hand, grip push rod again and go axially to tap bearing along left half axle by tapping section, during percussion, left half axle is inserted in dodge to avoid in hole producing and interferes, thus moves to bearing realize release bearing in left half axle in the axis hole being used for installing described bearing of flange.Due to tap time bearing this circumference be all stress, therefore bearing advance time unobstructed and be not easy damage.
As preferably, described left half axle is sequentially provided with bearings section and big footpath section, the diameter of described big footpath section less than the diameter of described bearings section, the diameter of described big footpath section with described in dodge the equal diameters in hole.Advancing bearing by the way of tapping the end of push rod, during this structure makes to advance bearing, bearing hardly suffers from power radially, therefore when advancing, bearing is more not easy damage.
As preferably, the other end of described push rod is provided with holding rod, and described holding rod is arranged with handle sleeve.Convenience during gripping can be improved.
As preferably, described handle sleeve is rubber sleeve.Comfortableness during gripping can be improved.
As preferably, described handle sleeve resilient sleeve is located at described holding rod, the elastic adjusting mechanism of the elastic force being provided with between described holding rod and handle sleeve between regulation handle sleeve and holding rod, described elastic adjusting mechanism includes the base tube being set in outside holding rod and being located in handle sleeve and is looped around the holding sheet outside described base tube, described holding sheet is constituted along the circumferentially distributed fricting strip of base tube by some pieces, described fricting strip is provided with some slide bars radially extended along base tube, described sliding bar is arranged in described base tube, the inner of described slide bar is provided with shift-in outside driving slide bar and drives fricting strip to be connected to the 3rd spring together with handle sleeve, described elastic adjusting mechanism is additionally provided with the pretightning force adjustment structure of the pretightning force regulating described 3rd spring.The gripping to holding rod is realized by gripping handle sleeve during use.Holding rod in the technical program has elasticity, thus comfortableness when improving use, the elastic effect in the technical program can also change, to adapt to different needs.The concrete regulation process of holding rod elasticity is, the 3rd spring moving radially along base tube is driven by pretightning force adjustment structure, so that fricting strip changes with the normal pressure of handle sleeve, thus realizing the change of pretightning force so that the size of the power that handle sleeve rocks relative to holding rod changes the elastic effect reaching different.
As preferably, described pretightning force adjustment structure includes the conical head of two tubular structures being supported on outside holding rod by base tube, conical head is driven to move axially and can make conical head to stop at the driving structure of setting position and some push rods, said two conical head is slidably connected in the two ends of described base tube in the way of miner diameter end is arranged oppositely, the two ends of described push rod are shelved on the conical surface of said two conical head, the all of described slide bar of same fricting strip passes through described spring supporting on same described push rod, the described slide bar of each piece of fricting strip is respectively supported by a described push rod.During regulation, realize push rod moving radially thus realize the push rod change along base tube radial position along base tube by the position of axially varying conical head, thus realize the change of the 3rd initial tension of spring.Convenience during regulation is good.
As preferably, described driving structure includes the jacking block in two two ends being threaded in described base tube, and said two conical head is between said two jacking block.Driving conical head to realize regulation by rotating jacking block, regulation puts in place, is automatically positioned, and convenience during use is more preferable.
This utility model has an advantage that and can be installed between left half axle and flange rapidly and accurately by bearing easily, and not easily leads to the damage of bearing, and installation rate is fast, and reduce automatic transmission remanufactures cost.
