Abstract
Bidirectional dustproof swivel joint of special three -ring speed reducer for pile driver, the dress is worn in the moving axis cover to the dead axle cover, the output shaft up end sets up transition disc, the transition disc bottom sets up the shield, the middle part of shield sets up oily felt, protection box of dead axle cover and the top installation of moving axis cover, the protection box suit is on slip casting elbow surface, two input shafts are close to slip casting elbow one side baffle of fixed mounting respectively, output shaft lower part surface sets up a graphite protective layer, the output shaft bottom is through splined connection piece and external connection. The utility model discloses an install a protection box at dead axle cover and moving axis cover top, set up the baffle simultaneously on one side of the input shaft, inside the effectual mud of having avoided the slip casting elbow to spatter outward got into swivel joint, the output shaft set up the spline simultaneously, has improved the bearing capacity of output shaft greatly, has reduced the wearing and tearing to adjacent subassembly, has simple structure, moves advantage stable and long service life.
Description
Technical field
The utility model relates to a machine transmission technology field, is specifically related to the two-way anti-gray swivel coupling of a kind of stake machine three-ring speed reducer special.
Background technique
In the construction works such as tall building, high-speed railway, bridge, often need piling, stake machine is can the machinery of a bored grouting pile.The special three-ring speed reducer of stake machine is the driving mechanism of a machine, the impulse force of stake machine operationally when the cement of high-pressure injection pump enters slip casting elbow is larger, the moving axis cover of retarder swivel coupling and dead axle socket position are in below slip casting elbow, easily rush in mud, and the input shaft of retarder is also near slip casting elbow, when operating at ordinary times, mud dust also easily enters in input shaft, causes wearing and tearing to axle.In addition the output shaft of existing retarder swivel coupling is by being connected key with outside, to key connect area of contact little, bearing capacity is lower, centering performance and steering capability unsatisfactory, and, stress dark to keyway is concentrated large, more serious to the strength reduction of axle and hub.
Model utility content
The utility model provides the two-way anti-gray swivel coupling of a kind of stake machine three-ring speed reducer special, and the mortar impurity existed to solve prior art enters swivel coupling and key stress concentrated to the problem causing greatly wearing and tearing.
Dead axle cover of the present utility model is installed in moving axis cover; output shaft upper-end surface arranges transition disc; bottom transition disc, dust cover is set; the middle part of dust cover arranges oil immersion felt; solving technological scheme that its technical problem adopts is that dead axle cover and moving axis overlap top and install a protective box; protective box is sleeved on slip casting elbow surface; two input shafts fixedly mount a dividing plate respectively near slip casting elbow side; output shaft lower surface arranges a graphite protective layer, is connected bottom output shaft by splined connection with outside.
The utility model is by installing a protective box at dead axle cover and moving axis cover top, dividing plate is set in input shaft side simultaneously, effectively avoid the mud spattered outside slip casting elbow and enter swivel coupling inside, output shaft arranges spline simultaneously, substantially increase the bearing capacity of output shaft, reduce the wearing and tearing to adjacent component, there is the advantage of simple, the stable and long service life of structure.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1 slip casting elbow, 2 output shafts, 3 input shafts, 4 dead axle covers, 5 moving axis covers, 6 dust covers, 7 oil immersion felts, 8 transition discs, 9 protective boxs, 10 dividing plates, 11 splined connection, 12 graphite protective layers in figure.
Embodiment
As shown in the figure; the two-way anti-gray swivel coupling of a kind of stake machine three-ring speed reducer special; dead axle cover 4 is installed in moving axis cover 5; output shaft 2 upper-end surface arranges transition disc 8; dust cover 6 is set bottom transition disc 8; the middle part of dust cover 6 arranges oil immersion felt 7; dead axle cover 4 and moving axis overlap 5 tops and install a protective box 9; protective box 9 is sleeved on slip casting elbow 1 surface; two input shafts 2 fixedly mount a dividing plate 10 respectively near slip casting elbow 1 side; output shaft 2 lower surface arranges a graphite protective layer 12, is connected bottom output shaft 2 by splined connection 11 with outside.
Claims (1)
