Description

Technical Field

[0001] The utility model relates to the technical field of cone crusher transmission, in particular to a cone crusher transmission device. Background Art

[0002] This machine is mainly composed of frame, transmission, hollow eccentric shaft, bowl-shaped bearing, crushing cone, adjustment device, adjustment sleeve, spring and hydraulic station for adjusting discharge port. When the crusher is working, the motor drives the eccentric sleeve to rotate through the horizontal shaft and a pair of bevel gears. The axis of the crushing cone performs a pendulum motion under the force of the eccentric sleeve, so that the surface of the crushing wall sometimes approaches and sometimes leaves the surface of the mortar wall, so that the ore is constantly squeezed and bent in the crushing chamber and crushed.

[0003] However, in the prior art, the existing cone crusher is mainly driven by a tapered key connection and a tapered roller bearing. The tapered roller bearing cannot withstand a large load and may be damaged if the load exceeds the limit. Therefore, the transmission shaft speed is limited. Utility Model Content

[0006] The beneficial effects of the utility model are as follows: the transmission main shaft body mainly plays the role of rotatable connection and support, the arranged pulley can facilitate the belt to be fixed on it, so that it can drive the rotation, the arranged bevel gear can replace the conical key connection and add a tapered roller bearing for transmission, so that the gear structure can be used for meshing transmission, the protective rotating sleeve can protect the outside of the transmission main shaft body, and a corresponding bearing seat is also arranged inside, so that the transmission main shaft body can be easily rotated, the arranged limiting circular plate can divide the area range, and the rotating mouth can be used to facilitate the insertion of one end of the transmission main shaft body into it, and a bearing seat is also arranged inside the rotating mouth to facilitate the rotation of the transmission main shaft body, and the through mouth can facilitate the screwing in and passing of the screw rod.

[0007] On the basis of the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, a mounting round seat is provided on the outer wall of the protective rotating sleeve near the other side.

[0009] The beneficial effect of adopting the above further solution is that the installation of the round seat can facilitate the use of the internal bearing seat to adopt a spherical roller bearing, thereby increasing the load and improving the rotation speed of the transmission main shaft body.

[0010] Furthermore, an injection port is provided on one side of the mounting round seat.

[0011] The beneficial effect of adopting the above further solution is that the provided injection port can facilitate the inspection of the internal transmission main shaft body and can also facilitate the injection of lubricating oil for use.

[0012] Furthermore, a mounting circular plate is provided on one side of the outer wall of the transmission main shaft body close to the mounting circular seat.

[0013] The beneficial effect of adopting the above further solution is that installing the circular plate makes it easier to set up the circular opening thereon.

[0014] Furthermore, one side of the mounting circular plate has four circular openings in a circular equidistant array.

[0015] The beneficial effect of adopting the above further solution is that the round opening can facilitate the screw rod to be inserted into the interior.

[0016] Furthermore, screw rods are arranged between the inner sides of the four circular openings, and nuts are arranged on the outer walls of the four screw rods.

[0017] The beneficial effect of adopting the above further solution is that the provided screw rod and nut can facilitate the fixed installation of the pulley thereon.

[0018] Beneficial effects: By using pulleys and bevel gears, it is possible to replace the traditional structure that relies on cone key connection and tapered roller bearings for transmission. This can increase the load to a certain extent and prevent damage caused by overload as much as possible. The transmission shaft speed can also be increased without any restrictions.
