Description
Technical Field
The utility model belongs to the field of design and manufacture of mining machinery, particularly belongs to the field of design and manufacture of a gyratory crusher, and particularly relates to a horizontal shaft lubricating structure of the gyratory crusher.
Background
As a crusher with the largest yield in the field of mine crushing, a gyratory crusher has the characteristics of stability, high efficiency, large crushing ratio and the like. The method is mainly applied to head breaking, does not need a feeder for feeding, and adopts a mode of directly pouring raw materials into the raw materials for feeding. During operation, the fretting load is therefore very high, in particular the horizontal shaft and its bearings responsible for transmitting the torque.
If the horizontal shaft is not lubricated smoothly, the temperature of the horizontal shaft bearing is too high, the play of the horizontal shaft bearing is reduced, so that the bearing is locked, and serious results are caused.
Therefore, a reasonable horizontal shaft lubricating structure of the gyratory crusher is needed for ensuring good lubrication and timely heat dissipation of the horizontal shaft.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a horizontal shaft lubricating structure which is good in lubricating effect and timely in heat dissipation.
A horizontal shaft lubricating structure of a gyratory crusher is characterized in that a groove is formed in the outer surface of a horizontal shaft, and the groove is sealed through an oil duct cover plate to form an external oil duct communicated with a drilling oil inlet channel;
the left end of the outer oil duct is communicated with an oil inlet pipe arranged at the left end of the horizontal shaft, the right end of the outer oil duct is communicated with an oil duct inner cavity of the horizontal shaft through an inner and outer connecting oil duct arranged at the right end of the horizontal shaft, lubricating oil in the oil duct inner cavity is used for lubricating a tapered roller bearing of the horizontal shaft, and an oil outlet pipe communicated with the oil duct inner cavity is further arranged at the left end of the horizontal shaft.
In the technical scheme, the external oil passage is communicated with the oil inlet pipe through a drilling oil inlet channel.
In the above technical scheme, the oil passage inner cavity and the oil outlet pipe are connected through the first oil outlet passage and the second oil outlet passage, specifically, the vertically arranged first oil outlet passage is connected with the oil passage inner cavity, and the horizontally arranged second oil outlet passage is connected with the first oil outlet passage and the oil outlet.
In the technical scheme, the periphery of the oil duct cover plate is welded and fixed by argon arc welding.
Due to the adoption of the technical scheme, the utility model has the following beneficial effects:
through advancing oil pipe oil feed, fluid flows into inner bearing through the oil duct, takes out inner bearing heat, flows to an oil pipe through the horizontal axis inner chamber, takes out inside heat and impurity. The oil duct is formed by adopting a plugging welding mode, and the periphery of the oil duct cover plate is welded by adopting argon arc welding. The oil outlet pipe is horizontally arranged, so that the inner cavity of the horizontal shaft is ensured to have sufficient oil.
