Abstract
The utility model discloses a lifting device for train wheel-pair bearing assembling press with accessories on the axle, comprising a lifting plate (13), a bracket (6) and a lifting plate driving device, a top block (3) on the lifting plate (13), axle sleeves (14) and slide-bars (15) on the side surface of the lifting plate (13) and the bracket (6) to make the lifting plate (13) vertically slide on the slide-bar (15); The lifting plate driving device comprises a motor (11) and a screw rod mechanism and a screw rod nut (4) is rotatably connected on the bracket (6) and a drive gear (7) is sleeved on the screw rod nut (4) and a screw rod (10)is extruded below the lifting plate (13) and an output gear (12) is permanently connected on the output axle of the motor (11) and the output gear (12) is in engagement transmission with the drive gear (7). The lifting device has simple structure and effectively lifts the wheel-pair with accessories on the axle to satisfy the bearing installation requirements.
Description
Technical field
The utility model relates to a kind of, and train wheel is to the lowering or hoisting gear of bearing press, especially a kind of lowering or hoisting gear of motor-car wheel set bearing pressing machine.
Background technology
Train wheel when bearing is installed be the special equipment bearing press mounting put carry out on the machine bearings mounted.The position relative fixed of bearing, when train wheel under the effect of bearing press lowering or hoisting gear, rising to the height adaptive with bearing, the bearing pressurizing unit will push bearing and slip into the axle head of train wheel to two ends, finish press-fiting of bearing.Existing train wheel is optical axis to the centre, and is accessible, and existing lowering or hoisting gear is to withstand the right optical axis of wheel with the oil cylinder butt joint, realizes lifting, easily looks for the position on optical axis, withstands optical axis lifting centering, the convenient bearing of installing.But install for the wheel set bearing of motor-car and since wheel between optical axis on also just like other annexes such as gearboxes, do not have supporting and space, therefore existing lowering or hoisting gear can't satisfy the requirement of motor-car wheel to lifting.
The utility model content
The purpose of this utility model be exactly solve existing lowering or hoisting gear to the motor-car wheel to realizing the problem of lifting, provide a kind of can be to the lowering or hoisting gear of motor-car wheel to last item pressure-bearing device machine.
The technical solution adopted in the utility model is: the lowering or hoisting gear of motor-car wheel set bearing pressing machine, it comprises lifter plate, support and is fixed on several lifter plate drive units on the support, lifter plate is provided with the right rail of support wheel, the side of lifter plate and support is provided with several corresponding axle sleeves, be provided with adaptive with it slide-bar in the axle sleeve, lifter plate can be slided up and down along slide-bar; Described lifter plate drive unit comprises motor, cooperates the screw body that constitutes with screw mandrel by the feed screw nut, the feed screw nut is rotatably connected on the support, go back suit on the feed screw nut and be connected with driven wheel, the upper end of screw mandrel is squeezed in the below of lifter plate, be connected with output gear on the output shaft of motor, output gear and driven wheel engaged transmission drive the screw mandrel lifting and realize the lifter plate lifting.
For spacing to carrying out, on the lifter plate, the inboard of two rails is fixed with and is used for to wheel to spacing block to wheel.By cooperating of block and rail, further to wheel to spacing.
Adopt technique scheme, during use, the right bottom surface of rail aligned wheels, starter motor, motor will drive the feed screw nut and rotate by the engaged transmission of output gear and driven wheel, because the feed screw nut position is fixing up and down, therefore screw mandrel will move up and down, the rail that promotes on the lifter plate that moves up and down of screw mandrel moves up and down, because rail is squeezed in wheel to last, thereby realizes wheel moving up and down, thereby finish centering, bearing is installed.
In sum, the beneficial effects of the utility model are: because the utility model is realized lifting to taking turns to carrying out roof pressure, therefore take turns convenient realization lifting for motor-car, finish the right bearing press mounting of wheel; Because the utility model gripper shoe is provided with rail and block to taking turns spacing, has increased the security of wheelset fitting bearing.
