A spindle of the bearing traction pin mechanism is a multi-segment rotating shaft. The diameters of the segments decrease from top to bottom sequentially and gradually. The spindle is arranged in the center of an inner cavity of a center plate seat. The two adjacent segments at the lower end of the spindle are respectively in matching connection with the inner rings of a radial spherical plain bearing and a thrust spherical plain bearing. The outer rings of the radial spherical plain bearing and the thrust spherical plain bearing are matched with the surface of the inner cavity of the center plate seat. The lower end surface of the outer ring of the thrust spherical plain bearing is arranged on the bottom of the inner cavity of the center plate seat. The lower ends of the spindle and the inner ring of the thrust spherical plain bearing are fixed by shaft end baffles. The upper end surface of the center plate seat is connected with a retainer ring and a dust ring sequentially. The bearing traction pin mechanism is connected between the body and the frame of the bogie of the railway crane. The design has small volume and light weight, not only can freely rotate in the horizontal plane and the vertical plane, but also can bear larger vertical load and transfer the vertical traction force and the vertical braking force so as to obviously improve the bearing capacity and flexibility of rotation of the railway crane.
Description
Technical field
A kind of carrying towing pin mechanism with multiple degree of freedom rotating function of the utility model belongs to hoisting crane field, particularly locomotive crane.
Background technology
At present, on the locomotive crane, connect car body and bogie truck at home and abroad, and the member of drive car body operation is mainly axle mechanism.It mainly acts on is to transmit longitudinal traction power and vertical braking force, and it also is a guideway vehicle when moving on warp rail simultaneously, the center of gyration that bogie truck rotates with respect to car body.
Axle mechanism mainly is made up of body center plate and truck center plate.Be provided with protruding sphere with the body center plate of car body concrete mutually, be provided with concave spherical surface with the truck center plate of bogie truck concrete mutually, the protruding sphere of body center plate is entrenched in the concave spherical surface of truck center plate, can relatively rotate between the two.Because body center plate and truck center plate are the entity foundry goods, can bear bigger vertical load, but also often volume and weight are bigger, manufacturing process is also very complicated.Simultaneously, rotate also very dumbly, directly influenced the dynam drive ability of hoisting crane.It is big to go up between the spherical contact surface of truck center plate friction drag in addition, and so easily abrasion are having relatively high expectations to lubricating condition.
Along with the raising of modern railways running velocity, the limitation of above-mentioned axle mechanism is more and more obvious, therefore needs badly and uses novel mechanism to substitute.
The utility model content
But the purpose of this utility model provides the carrying towing pin mechanism that a kind of multiple degree of freedom rotates, this mechanism not only can freely be rotated in horizontal surface and vertical plane surface, and can bear bigger vertical load, transmission longitudinal traction power and vertical braking force, volume is little, from heavy and light.Can significantly improve the locomotive crane dynamic performance.
The purpose of this utility model is achieved through the following technical solutions:
But the carrying towing pin mechanism that a kind of multiple degree of freedom of the utility model rotates, by axle, center filler, plain radial bearing, thrust articulated bearing, the axle head baffle plate, positioning retainer ring and dust ring are formed, be characterized in that axle is step-like rotating shaft, the diameter of each sections from top to bottom reduces successively by joint, axle is arranged on the center filler lumen centers, plain radial bearing and thrust articulated bearing are respectively from top to bottom, adjacent two sections successively in the axle bottom are connected, entad, the outer ring of thrust articulated bearing all cooperates with the center filler surface of internal cavity, lower surface, thrust articulated bearing outer ring places center filler inner chamber bottom surface, plain radial bearing inner ring lower surface is supported on thrust articulated bearing inner ring upper surface, lower end at axle and thrust articulated bearing inner ring is fixed with the axle head baffle plate, the upper surface of center filler and edge, thrust articulated bearing outer ring are connected with positioning retainer ring, are provided with dust ring between the upper surface of positioning retainer ring and axle respective step bottom surface.
Above-mentioned with entad, the axle center of two oscillating bearing sections of cooperation of thrust, offer the downward oilhole that send; The hollow hole adaptive with the axle head baffle plate arranged in the bottom of center filler.
The design guarantees that two oscillating bearing center of gyrations are all on the same centre of sphere; Lower surface at axle and thrust articulated bearing inner ring is fixedly connected with the axle head baffle plate; so can prevent that axle from moving up and down with respect to the inner ring of thrust articulated bearing; for avoiding axle head baffle plate and center filler to interfere; in the center filler bottom corresponding hollow hole is arranged; in addition, positioning retainer ring can prevent that the plain radial bearing outer ring from moving up and down with respect to center filler, and dust ring is except that having good sealing and dustproof effect; when stressed, also can protect the normal rotation of axle by self plastic deformation.Simultaneously, the axle center send oilhole, its oil inlet is in the lower surface of axle, provide lubricated to oscillating bearing from bottom to top, and because of thrust articulated bearing is positioned at the bottom of plain radial bearing, so thrust articulated bearing also can be lubricated simultaneously, thereby improved the alerting ability that mechanism rotates.
When but the carrying towing pin mechanism that the design's multiple degree of freedom rotates is used for locomotive crane, be connected with the locomotive crane car body with the upper surface of bolt with axle respectively, center filler is connected with the framework of locomotive crane bogie truck.
When locomotive crane when the warp rail of superelevation of outer rail is arranged, car body drives axle and rotates with respect to bogie truck, axle then drives the inner ring of plain radial bearing and thrust baring, freely rotate in horizontal surface or vertical plane surface with respect to outer ring separately, center of turn is on the same centre of sphere of two oscillating bearings, in the rotating process, car body keeps level substantially.
Because the sphere of two oscillating bearings is concentric, therefore, is drawing back operating mode, tractive force passes through the centre of sphere.
Locomotive crane is when hoisting operation or loopback, and the above weight of bogie truck directly vertically is delivered on the center filler by axle and thrust articulated bearing, is delivered on the truck frame by center filler again.At this moment, the effect of bearing vertical load has been played by towing pin mechanism.
