Abstract
The utility model relates to an oil injection structure of a mining motor. The oil injection structure comprises a motor end cover, a bearing end cover, an outer bearing cover, an inner bearing cover and a bearing, wherein the motor end cover is internally provided with a longitudinal oil injection hole; the outer bearing cover is internally provided with a horizontal oil injection hole; the horizontal oil injection hole passes through the end cover and is communicated with an oiling groove formed in the inner bearing cover; the oiling groove is communicated with an oil storage cavity of the bearing; the longitudinal oil injection hole is connected with the horizontal oil injection hole by an oil injection hose; and an oil cup is arranged at an oil injection port of the longitudinal oil injection hole. By the oil injection structure, a motor bearing can be well lubricated and cooled all the time; and the oil injection structure is very convenient in oil injection and is not limited by space, thereby guaranteeing safe operation of the bearing.
Description
Technical field
The utility model belongs to mine motor appurtenances technical field, is specifically related to a kind of mine motor oil injection structure.
Background technique
mine motor is because being limited by installing space, require its compact structure, cause size nervous, conventional oil injection structure is arranged on the bearing end cover lateral part, oil filler pipe by the outside respectively with bearing end cover on pouring orifice be connected with lubricating cup, this kind structure easily causes interference to the operation of motor, because the structural characteristics of mine motor is limit, conventional oil injection structure can not satisfy its requirement, this just makes some mine motors in the use of reality, cancelled oil injection structure, bring unsafe factor for thus the operation of bearing, in case insufficient lubrication appears in motor bearings, can cause damaged because of bearing or burn and cause stopping accident.
The model utility content
The purpose of this utility model is to overcome defective of the prior art, and a kind of space and structural limitations of not being subjected to is provided, and guarantees the mine motor oil injection structure of bearing safe operation.
Realize that the technological scheme that the purpose of this utility model is taked is: this structure comprises electric motor end cap, bearing (ball) cover, bearing end cover, internal bearing cover and bearing, wherein, be provided with vertical oil hole on electric motor end cap, bearing end cover is provided with horizontal oil hole, this horizontal oil hole passes the oiling groove that arranges on bearing (ball) cover and internal bearing cover and is connected, oiling groove is connected with the oil storage chamber of bearing, vertically be connected by filling neck between oil hole and horizontal oil hole, lubricating cup is equipped with in the oiling port of vertical oil hole.
The end that described horizontal oil hole is connected with filling neck is equipped with the pouring orifice joint.
Described filling neck is the asbestos flexible pipe, one of flexible hose covered with plastic film or Stainless Steel Flexible Hose.
According to the mine motor oil injection structure that such scheme is made, can make motor bearings can access good lubrication and cooling all the time, and oiling is very convenient, has the spatial constraints of not being subjected to, guarantee the advantage of bearing safe operation.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Referring to Fig. 1, the utility model is the mine motor oil injection structure, comprise electric motor end cap 5, bearing (ball) cover 7, bearing end cover 3, internal bearing cover 8 and bearing 10, wherein, be provided with vertical oil hole 4 on electric motor end cap 5, bearing end cover 3 is provided with horizontal oil hole 6, this horizontal oil hole 6 passes the oiling groove 9 that arranges on bearing (ball) cover 7 and internal bearing cover 8 and is connected, oiling groove 9 is connected with the oil storage chamber 11 of bearing 10, vertically be connected by filling neck 1 between oil hole 4 and horizontal oil hole 6, lubricating cup 2 is equipped with in the oiling port of vertical oil hole 4.The end that described horizontal oil hole 6 is connected with filling neck 1 is equipped with pouring orifice joint 12.Described lubricating cup 2 is M10 * 1 lubricating cup, and pouring orifice joint 12 is M10 * 1 end formula joint.Described filling neck 1 can adopt the asbestos flexible pipe, one of flexible hose covered with plastic film or Stainless Steel Flexible Hose.This filling neck 1 has good flexural property, can satisfy different working condition lower bearing oiling problems.
