Abstract
The utility model relates to a cone crusher belt pulley expansion sleeve device. A cone expansion sleeve is arranged between a belt pulley and a main shaft; an inner hole of the cone expansion sleeve is in transition fit with the main shaft; a set screw is mounted at the position, aligned to a key of the main shaft, of the cone expansion sleeve; the belt pulley is fixed on the cone expansion sleeve by a draw-in bolt. According to the utility model, the expansion sleeve is fixed on the main shaft in a static connection manner, so that the transmission rotation moment is stable; the belt pulley is in taper connection with the expansion sleeve, so that the assembling and disassembling are convenient.
Description
Technical field
The utility model belongs to engineering mechanical device technical field, relates to the cone machine belt pulley expanding sleeve device that a kind of transmission shaft for cone machine is connected with belt pulley.
Background technique
The transmission shaft that is illustrated in figure 1 existing cone machine with being connected of belt pulley is: main shaft 1 external diameter and belt pulley 5 endoporus, with appropriate magnitude of interference, coordinate and be assembled together, with key 2, carry out again the transmission of torque, shaft end ring 3 for tail end, by the tooth hole on bolt and lock nut 4 and main shaft 1, belt pulley 5 is pressed on main shaft, in case axial float.This kind of structure has makes simply, transmit the advantages such as stable, but it also has a fatal shortcoming, during maintenance dismounting very difficult, when especially service time is longer, between belt pulley and main shaft, there is corrosion, that just cannot be dismantled, and can only destroy belt pulley and just can keep in repair.
model utility content
In order to overcome the above-mentioned shortcoming of prior art, the utility model provides that a kind of driving torque is stable, simple load and unload cone machine belt pulley expanding sleeve device.
The utility model solves the technological scheme that its technical problem adopts: a kind of cone machine belt pulley expanding sleeve device, between belt pulley and main shaft, be provided with cone expansion set, between the endoporus of cone expansion set and main shaft, it is transition fit, cone expansion set is equipped with Cock screw in the position of aiming at key on main shaft, and belt pulley is fixed on cone expansion set with turnbuckle.
The keyway of the endoporus of belt pulley is meshed with the key on main shaft.
Cone expansion set is for opening limit structure, in the seam that is axially arranged with 5-6mm of cone expansion set, the connection bolt lock stressed joint of the seam after assembling.
Turnbuckle is fixed on belt pulley on cone expansion set at the through hole of corresponding position by the tapped hole in the large end flange of cone expansion set and belt pulley.
On belt pulley, be provided with two symmetrical tapped holes
of 180 degree that can make knockout screw axis be screwed into.
The beneficial effects of the utility model are: expansion set is fixed on main shaft by static connection mode, and driving torque is stable, and belt pulley is connected with expansion set and adopts tapering to connect, and installs and removes and facilitates.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art.
Fig. 2 is structural representation of the present utility model.
In figure: 1-main shaft, 2-key, 3-shaft end ring, 4-locking nut, 5-belt pulley, 6-cone expansion set, 7-Cock screw, 8-knockout screw, 9-stretching screw.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Referring to Fig. 2, a kind of cone machine belt pulley expanding sleeve device is provided with cone expansion set 6 between belt pulley 5 and main shaft 1, the tighter transition fit of employing between endoporus and the main shaft 1 of cone expansion set 6, and realize transmission of torque with key 2; For convenient disassembly, cone expansion set 6 adopts opens limit structure, and at the seam that axially cuts 5-6mm of cone expansion set 6, after assembling, with connecting bolt locking, for it slides axially, cone expansion set 6 is equipped with Cock screw 7 in alignment keys 2 positions, makes axle form stable static connection; In the large end flange of cone expansion set 6, be drilled with several tapped holes, belt pulley 5 is drilled with through hole at corresponding position, belt pulley 5 is fixed on and is bored on expansion set 6 with turnbuckle 9.For convenient disassembly, on belt pulley 5, be drilled with two the 180 symmetrical tapped holes of degree, during dismounting, the turnbuckle 9 that gets loose, then be screwed into knockout screw 8 axis, can tear belt pulley 5 open unmount very convenient.
The utility model is fixed on expansion set on main shaft by static connection mode, and driving torque is stable, and belt pulley is connected with expansion set and adopts tapering to connect, and installs and removes and facilitates.
