Abstract
The utility model discloses a totally-enclosed ground roller for a mine winch to restrict the movement of a drawing wire rope, which comprises a shaft, a wheel hub and a round tube, and is a three-pieced hollow totally-enclosed ground roller. The utility model is convenient to produce, install, maintain and clean up the sand grains on the cast, and guarantees the concentricity. The luboil is injected into the core space of the ground roller through an oil cup in time, and the reinforced seal and the seal ring can avoid leakage of the luboil, thereby the bearing is kept in a long-term and nice lubricating state, has a long service life, avoids the sparks caused by the friction of the drawing wire rope, and guarantees safety.
Description
Technical field
The utility model relates to a kind of mining machinery, specifically be mounted on the winch as the spacing Ground roller of haulage cable.
Background technology
Ground roller is the vitals of mine winch, and it protects the sense of motion of index steel rope effectively, prevents the steel rope friction that mops floor.Owing to working environment evil under the mine especially mine is strong, it is serious that old-fashioned Ground roller decreases ring.
The major cause that old-fashioned Ground roller damages is that problem is arranged on the design and processes, original design Ground roller body is that inblock cast comes out, core is used in the moulding of inner chamber position at present, internal cores can't be cleaned out after casting finished product, a large amount of sands are left at the dead angle, and in use, the sand in the inner chamber comes off in running and vibrations process, enter bearing, cause bearing stuck.Because two head bearings of axle are lubricated by butter, bearing is sealed at both ends bad, and exterior mud, water, dust and other impurities enter bearing, cause bearing stuck.Ground roller is difficult to solve the problem of concentricity on Vehicle Processing technology, very roller shaft can't guarantee concentricity when assembling, and heating when causing the rotation of two head bearings also can cause bearing stuck.
Summary of the invention
The purpose of this utility model is in order to solve the shortcoming that old-fashioned Ground roller exists, to design the totally-enclosed Ground roller by axle, wheel hub and three combinations of pipe, inject lubricating oil by the lubricating cup that is installed in wheel hub one side to the Ground roller inner chamber, bearing outside installation balladeur train oil sealing.
The utility model is realized with following technical scheme: a kind of totally-enclosed Ground roller, comprise axle, and by the wheel of bearing installation on axle, it is characterized in that: thin ends and thick middle two bearings of axle two ends suit; Two disc wheelboss inner holes are sleeved on the external cylindrical surface of bearing; Two annular arrangement outside framework oil seals are sleeved on the axle in the bearing outside; Two disc bearing cap shims by some screw retention on the lateral surface of wheel hub; The pipe two ends clamp seal ring by the centre of some screw retention at two wheel hubs on the contact surface between pipe endoporus and the wheel hub; Lubricating cup and the inner chamber perforation by oilhole and Ground roller are installed in the outside of one side wheel hub.
Good effect of the present utility model is:
1, the totally-enclosed Ground roller that is combined into by axle, wheel hub and three of pipes is rational in infrastructure, is convenient to processing, assembling and maintenance.
2, in time inject lubricating oil by lubricating cup to the Ground roller inner chamber, outside framework oil seal and seal ring have guaranteed that lubricating oil can not leak, and make bearing be in good lubricating status, long service life, avoid the traction steel wire friction to produce spark effectively, make borehole operation safe and reliable.
3, thoroughly solved old-fashioned Ground roller sand removal not thoroughly and the shortcoming of concentricity difference.
Description of drawings
Accompanying drawing is the utility model structural representation.
Among the figure: 1, axle, 2, outside framework oil seal, 3, bearing, 4, screw, 5, bearing cap shim, 6, wheel hub, 7, screw, 8, pipe, 9, lubricating cup, 10, seal ring.
The specific embodiment
As shown in drawings, thin ends and thick middle axle 1 two ends bearing set 3, the ring end face leans against the major diameter two ends of axle 1 in the bearing 3, the inner hole sleeve of two wheel hubs 6 is contained on the outer shroud of bearing 3, two bearing cap shims 5 are installed by screw 4 in the outside of wheel hub 6, suit outside framework oil seal 2 on the axle 1 of bearing cap shim 5 inboards, pipe 8 is fixed on the inboard of two wheel hubs 6 by some screws 7, clamp seal ring 10 so totally-enclosed Ground rollers that just form hollow on the contact surface of wheel hub 6 and circle pipe 8, be convenient to processing, assemble and maintenance, guarantee the axle 1 and wheel hub 6 of Ground roller effectively, the concentricity of pipe 8.
As shown in drawings, lubricating cup 9 is installed on the wheel hub 6 of a side, and is connected by oilhole and Ground roller inner chamber; Can adorn the inner chamber that lubricating oil injects Ground roller timely, outside framework oil seal 2 and seal ring 10 are avoided the leakage of lubricating oil, make bearing be in good lubricating status for a long time, greatly in the service life of improving Ground roller, the spark of avoiding the haulage cable friction to cause makes production safer.
