Description
Technical field
The utility model belongs to railway equipment manufacturing technology field, relates in particular to the provision for disengagement of a kind of goat main shaft.
Background technology
At present, goat has been distributed on domestic each bar railway service main widely as the track switch conversion equipment.Because railway delivery pressure is big, causes goat to act frequently, the part parts are in state of wear for a long time, and this just requires goat is carried out periodic inspection.Wherein the goat of part maintenance requires its main shaft is dismantled and assembled, and collar bush and goat casing adopt tight fit, depending merely on the artificial unloading gets up to waste time and energy, this device that just needs a cover can the underworker to dismantle main shaft improves the efficient of goat maintenance, and the provision for disengagement of goat main shaft is invented for addressing this problem.Yet defectives such as early stage goat main shaft provision for disengagement often exists that volume is big, Heavy Weight and power output deficiency have influenced the overhaul efficiency of goat.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of volume is little, in light weight, output pulling force main shaft provision for disengagement big, simple in structure and easy and simple to handle.
The technical scheme that the utility model is taked is:
The provision for disengagement of a kind of goat main shaft comprises support claw 1, support shell 6, bonnet 7, gear pair, manual axle 9, screw rod cover 2, screw rod 4 and removal rod 3, and it is characterized in that: the support shell front end is provided with 3 support claws; Form the column type casing by support shell and bonnet; Removal rod inserts from the endoporus of screw rod, is stuck in the screw rod endoporus by the shaft shoulder, and removal rod front end external screw thread matches with the internal thread of goat main shaft; The screw rod cover is formed the worm drive pair with screw rod, is shaped on screw rod keyway 5 in the both sides of screw rod, cooperates with the anti-rotation feather key of support shell front end; Screw rod cover and gear wheel 8 are connected by key, manually spool are connected by key with pinion 10, and large and small gear is two involute cylindrical gears such as displacement such as grade, forms described gear pair.
Further, described gear pair modulus is 1.5, and wherein pinion 10 adopts normal shift, the number of teeth 12, and gear wheel 8 adopts negative addendum modification, the number of teeth 59, gearratio is 5: 1.
Further, described manual shaft end is cuboid.
The beneficial effects of the utility model are:
Profile of the present utility model is that front end has the column type casing of " three-jaw ", to provision for disengagement location and support, has dwindled the volume of self by " three-jaw "; Step-up system adopts involute cylinder profile modified gear decelerator, compares with Related product in the past, and its speed reducing ratio has had significantly and improves; Load transfer device adopts screw rod cover and screw rod to form the worm drive pair, and torque axis is changed to straight line force output, and principle is simple, and part is easy to processing; The method that the anti-rotation guider of screw rod all adopts the key of casing to match with the screw rod keyway, structure are compact more, and intensity is higher; Rear cover material adopts the lighter aluminium of quality, has alleviated installation weight.

The specific embodiment
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
Goat main shaft of the present utility model provision for disengagement, as shown in Figure 1, 2, its primary structure comprises support claw 1, support shell 6, bonnet 7, gear pair, manual axle 9, screw rod cover 2, screw rod 4 and removal rod 3 etc." three-jaw " design shown in Figure 2, that provision for disengagement is made up of support claw, " three-jaw " external diameter of support shell front end is Ф 136.5, and the gap between the counterbore internal diameter of goat casing is approximately 0.25mm; The bonnet aluminium of provision for disengagement is a material, to alleviate its weight; Gear pair waits the displacement involute cylindrical gear to form by two, and modulus is 1.5, and wherein pinion 10 adopts normal shift, the number of teeth 12, and gear wheel 8 adopts negative addendum modification, the number of teeth 59, gearratio is 5: 1; Manually shaft end is processed into cuboid, so that electric wrench is imported as power source; The screw rod cover is formed the worm drive pair with screw rod, the rotation of screw rod cover, and screw axial moves, and for preventing the screw rod rotation, at the both sides of screw rod keyseat 5, cooperates with two anti-rotation feather keys of support shell front end, can guarantee the screw rod rectilinear motion; Removal rod inserts from the endoporus of screw rod, is stuck in the screw rod endoporus by the shaft shoulder, and its front end external screw thread matches with the internal thread of goat main shaft.Except that thrust ball bearing, all the other bearings select that quality is little, the sliding bearing of compact conformation for use.During work, earlier removal rod is screwed into main shaft with electric wrench, again by the manual axle of electric wrench rotation, moment of torsion process speed reducing gear pair and the worm drive pair that electric wrench produced, be delivered to the shaft shoulder of removal rod by the counterbore of screw rod, be converted to the pulling force (theoretical pulling force can reach about 90kN) of removal rod, thereby main shaft is pulled out goat.
Goat main shaft of the present utility model provision for disengagement owing to adopt above-mentioned structural design, has realized that volume is little, in light weight, power output is big, target such as easy and simple to handle simple in structure.
