Description
Technical Field
The utility model belongs to the bearing roller axle on the colliery is sticky tape transport in the pit, concretely relates to special axle of bearing roller.
Background
The roller carrier shaft is a key part of the underground coal mine belt conveyor and is one of parts with more use in the belt conveyor, and the structure and the quality of the roller carrier shaft are directly related to the service life and the production efficiency of the conveyor. The bearing roller shaft used in the current production generally has the defects of heavy weight and more material consumption, and in the running process, because the bearing roller shaft and the bearing are taken as a whole, the bearing roller shaft bears load and is easy to wear, and once the bearing roller shaft breaks down, the bearing on the bearing roller shaft is difficult to disassemble, so that the bearing roller shaft is time-consuming and labor-consuming in the process of maintenance and is not safe.
Disclosure of Invention
The utility model aims at overcoming the defect that prior art exists, providing a simple structure, precision height, strong adaptability, long service life's bearing roller axle.
The main technical scheme for achieving the purpose is that the special shaft for the carrier roller is characterized in that four symmetrical clamping grooves are formed in the circumferential surfaces of two sides of a shaft body at intervals, two half-opening type clamping grooves are formed in the right end surface of the shaft body, and two closed clamping grooves are formed in the left end of the shaft body.
As the utility model discloses preferred technical scheme, four symmetrical draw-in grooves that the interval was equipped with on the periphery of axis body both sides, wherein are close to and are equipped with the axle check ring in two inboard draw-in grooves of axis body respectively for the axial of bearing is spacing, is close to and is equipped with labyrinth seal circle in two draw-in grooves in the axis body outside respectively, is used for controlling labyrinth seal's axial and moves, eliminates labyrinth seal because of the mechanical friction that the axial moved and causes.
As the utility model discloses preferred technical scheme, axis body both ends plane on respectively be equipped with a B type centre bore, the axis body of being convenient for supports location processing.
As the preferred technical proposal of the utility model, the shaft body adopts 45#The cold-drawing high-quality carbon round steel is processed, has good mechanical property and high coaxiality, and is beneficial to the high efficiency and safety of the coal mine rubber belt conveyorComplete, reliable, stable and normal operation.
The utility model has the advantages that: first, the shaft body adopts 45#The cold-drawn high-quality carbon round steel is manufactured by cold-drawing high-quality carbon round steel, has good mechanical property, high mechanical strength, long service life and very stable coaxiality, straightness and cylindricity, improves two technical levels of surface roughness and can reduce the manufacturing cost by 10 percent; the two ends of the shaft body are respectively provided with the closed clamping groove and the semi-open clamping groove, so that the application range of the shaft body is expanded, and the belt conveyor belt roller can be widely applied to a turnabout drum, a groove-shaped carrier roller, a buffer carrier roller, a lower carrier roller, an aligning carrier roller, a detection vertical carrier roller, a friction deviation correcting carrier roller, a sweeper friction carrier roller, a professional production line roller conveyor and a small guide drum, not only is the maintenance and the use of the carrier roller convenient, but also the high-efficiency, safe, reliable and stable normal operation of the belt conveyor belt is ensured; and thirdly, four clamping grooves are formed in two sides of the shaft body, shaft retaining rings are respectively arranged in the two clamping grooves close to the inner side of the shaft body and used for axially limiting two discs of bearings, labyrinth sealing rings are respectively arranged in the two clamping grooves close to the outer side of the shaft body, axial movement of the labyrinth seals is controlled, mechanical friction caused by the axial movement of the labyrinth seals is eliminated, the running resistance of the carrier roller is effectively reduced, the transport capacity and the production efficiency of the belt conveyor are improved, the running noise of the carrier roller is reduced, the electric energy consumption is greatly reduced, and the energy-saving and emission-reducing effects are realized.
