Description
Technical field
The invention belongs to trunnion shaft field, relate in particular that a kind of bracket assembly is welded by steel plate splicing and by the welded type balance shaft assembly of left half axle and right axle shaft Compositional balance axle.
Background technology
What dumper adopted with balance shaft assembly support at present is cast member, axle and support are connected with to beat to sell to fix and close fixing with rivet hot, in the time that having crackle, support there is no effective maintenance means, crack like this, wear and tear, must change when the fault such as fracture simultaneously the connector of axle and support at support or axle, even if just one of them part has fault also must all change, make maintenance cost high; The balance shaft assembly working environment that now dumper is used is in addition all more severe, because oil sealing end face is to be directly exposed to airbornely, causes dust and muddy water to be easier to enter into oil sealing cutting edge, and oil sealing cutting edge is scratched and premature failure.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of dumper balance shaft assembly of being convenient to maintenance.
For solving the problems of the technologies described above, the invention provides a kind of welded type balance shaft assembly, comprise bracket assembly, described bracket assembly comprises the balanced body with arcuate recess, described balanced body bottom is provided with support, described balanced body and support form the space of a frame type, described balanced body two ends are also respectively arranged with trunnion shaft mount pad, on described two trunnion shaft mount pads, be respectively arranged with left axis hole and right axis hole, in described left axis hole and right axis hole, be respectively arranged with left half axle and right axle shaft, described left half axle and right axle shaft Compositional balance axle, between described left half axle and right axle shaft and bracket assembly for removably connecting, on described trunnion shaft mount pad cylindrical, be provided with dust cover.
Preferably, the balanced body of described bracket assembly, support and trunnion shaft mount pad are welded by steel plate splicing, between described balanced body and support and trunnion shaft mount pad, are and are welded to connect, and the material of described steel plate is 16Mn steel.
Preferably, described balanced body and trunnion shaft mount pad top are all welded with support base plate.
Preferably, described left half axle and right axle shaft inner end are provided with respectively left pressing plate and right pressing plate, with bolts between described left pressing plate and right pressing plate and left half axle and right axle shaft.
Preferably, described left half axle and right axle shaft periphery are socketed with axle housing respectively, between the left half axle of described axle housing and trunnion shaft and right axle shaft, are connected by bearing, between described bearing and axle housing, are provided with oil sealing, and described oil sealing end is provided with dust cover.
Preferably, described dust cover one end is arranged on the cylindrical of semiaxis, and the other end is arranged on axle housing cylindrical.
Preferably, described left half axle and right axle shaft outer end are provided with end cap.
The operation principle of the welded type balance shaft assembly that technical solution of the present invention proposes is:
Balance shaft assembly is connected and fixed by the support base plate on bracket assembly, front-rear axle distance rod, axle housing three parts and vehicle frame;
Axle housing is connected with left half axle and the right axle shaft of trunnion shaft by bearing, and axle housing can be taken exercises with respect to the left half axle of trunnion shaft and right axle shaft; Bearing makes the bearing enclose can locking by being added in the gear oil of axle housing, and oil sealing makes gear oil not reveal; End cap effect is also that gear oil is not revealed;
Vehicle frame transmits power by leaf spring to axle housing by the carrying force of vehicle body, axle housing swings with respect to left half axle and the right axle shaft of trunnion shaft because of the vibrations of leaf spring, if the bad axle housing of road conditions also can be made in the vertical tremor on trunnion shaft with the bob of leaf spring, vehicle frame is delivered to the carrying force of vehicle body on support base plate by intermediate support simultaneously, make a part of load of trunnion shaft carrying vehicle frame, and it is also the same time, front-rear axle makes trunnion shaft and front-rear axle formation interlock entirety make front-rear axle load be evenly distributed by distance rod active force on trunnion shaft simultaneously, thereby make trunnion shaft and front-rear axle form the suspended structure of organic integrated support vehicle body load.
Adopt the beneficial effect of technique scheme to be:
Bracket assembly overall structure all adopts 16Mn steel plate splicing to be welded, this structure effectively raises its bearing capacity compared to the balance shaft support of spheroidal graphite cast-iron QT500-7 casting of the prior art, tensile strength is also increased to 630Mpa by original 500Mpa, and bracket assembly adopt the structures shape that is welded of steel plate splicing its be convenient to the feature of maintenance, in the time that cracking fault, support can weld maintenance, do not need to change, save maintenance cost; The balanced body of while bracket assembly has increased the contact area with crossbeam, and the power of support installed surface in unit are has been reduced, and has extended the service life of support;
Trunnion shaft adopts breakaway-element to be made up of left and right half, and when axle fracture or wearing and tearing time can be changed separately semiaxis, and the original integral shaft cost of half axial ratio is low;
The left half axle of bracket assembly and trunnion shaft and the connected mode of right axle shaft adopt pressing plate to be connected with bolt arrangement, easy to maintenance, Panasonic's bolt and the pressing plate fault semiaxis of can dismantling;
Dust cover one end is arranged on semiaxis cylindrical, and the other end is arranged on axle housing cylindrical, avoids oil sealing port directly to contact with air, reduces muddy water and greasy dirt and enters into oil sealing cutting edge, improves the service life of oil sealing.
