Abstract
The utility model provides a lubricating and sealing structure for a thrust wheel of a crawling crane, which is characterized in that: the lubricating and sealing structure consists of an oil hole, an oil tank and a spring energy-storage sealing ring, wherein lubricating greases are filled in the oil hole, the oil tank and the spring energy-storage sealing ring; the oil hole comprises a longitudinal oil hole and a transverse oil hole which are respectively arranged in a pin shaft of the thrust wheel; the longitudinal oil hole extends to the inner part of the pin shaft from one side of the pin shaft, the oil groove is arranged between a shaft sleeve of the thrust wheel and the pin shaft, and the longitudinal oil hole is communicated with the oil tank through the transverse oil hole; the spring energy-storage sealing ring is arranged between the pin shaft of the thrust wheel and a thrust plate, an inner circle of the thrust plate is provided with a ring-shaped groove matched with the spring energy-storage sealing ring, and the ring-shaped groove is in contact with a lip of the spring energy-storage sealing ring. The spring energy-storage sealing ring has strong compensating capability for the radial shaking caused by gaps of the pin shaft and the shaft sleeve after abrasion; and the side surface of the pin shaft can be punched to fill the lubricating greases to achieve a good lubricating effect for components at the inner part of the thrust wheel.
Description
Technical field
The utility model relates to a kind of lubricated and packing technique of caterpillar wheel of crawler crane.
Background technology
The caterpillar wheel of middle-size and small-size crawler crane generally adopts the lubrication sealing structure of floating seal ring.The bearing pin of large-scale crawler crane caterpillar wheel is directly to be through between two blocks of track frame webs, because the displacement of floating seal ring axial compression is not installed, the floating seal ring can't be set.This position is utilizable small-sized, adopts the sealing of narrow lip-type seal or O type, and it is moving to be difficult to realize compensating diameter clearance string bigger between bearing pin and the axle sleeve.
The utility model content
The technical problems to be solved in the utility model is: a kind of lubricated and hermetically-sealed construction of crawler crane caterpillar wheel is provided, solves diameter clearance string bigger between compensation bearing pin and the axle sleeve and may I ask topic.
The utility model is to solve the problems of the technologies described above the technical scheme of being taked to be: the lubricated and hermetically-sealed construction of crawler crane caterpillar wheel, it is characterized in that: it is made of oilhole, oil groove and spring energy-storage seal ring, is full of grease in oilhole, oil groove and the spring energy-storage seal ring; Described oilhole comprises vertical oilhole and horizontal oilhole, all is located in the bearing pin of caterpillar wheel; Wherein vertically oilhole extends to bearing pin inside by a side of bearing pin, and described oil groove is located between caterpillar wheel axle sleeve and the bearing pin, vertically between oilhole and the oil groove by horizontal oilhole conducting; Described spring energy-storage seal ring is located between caterpillar wheel bearing pin and the thrust plate, and the interior circle of described thrust plate is provided with the circular groove that is complementary with the spring energy-storage seal ring, and circular groove contacts with the lip of spring energy-storage seal ring.
Press such scheme, described vertical oilhole extends to the bearing pin mid point along the axis setting of bearing pin.
Press such scheme, described spring energy-storage seal ring comprises a teflon seal ring, is provided with stainless steel spring in the teflon seal ring.
Principle of work of the present utility model is: be provided with bearing pin in the former caterpillar wheel, be provided with axle sleeve and thrust plate between caterpillar wheel and the bearing pin.The utility model is provided with vertical oilhole of ganging up, horizontal oilhole and oil groove in bearing pin, the interior circle of thrust plate is provided with circular groove, and circular groove is equipped with the spring energy-storage seal ring; Spring energy-storage seal ring and bearing pin cooperate, and the lip of spring energy-storage seal ring is installed outwardly.
The oil outlet of electronic grease pump is connected with vertical oilhole with pipeline by oil distributor carries grease, grease is through vertically oilhole, horizontal oilhole, oil groove are lubricated the contact surface between bearing pin and the axle sleeve, unnecessary grease is extruded by the lip of spring energy-storage seal ring, lubricated thrust plate prevents that simultaneously extraneous mud from entering axle sleeve.
The beneficial effects of the utility model are: the spring energy-storage seal ring radially rocks stronger compensation ability for what bearing pin and axle sleeve wearing and tearing post gap caused, by playing good lubricating effect to the caterpillar wheel INT COMP from bearing pin side punching input grease.
