Abstract
The utility model relates to an oil filling and oil draining mechanism of a motor bearing, which is designed for improving the disadvantages that the existing motor needs to take off an end cap and a bearing cap when filled with fuel and has complex operation and low lubricating property because the existing motor has no scavenge oil discharging paths. An oiling path and an oil discharging path are respectively arranged in the end cap of the motor, the oiling path is connected with an oiling cavity which is connected with one end of a bearing ball track, the other end of the bearing ball track is connected with an oil discharging cavity connected with the oil discharging path, an oil plug is arranged at a port of the oil discharging path, and an oil seal head is arranged at a port of the oiling path. When oil is filled in or discharged out of the motor, a user only needs to take off the oil seal head or the oil plug, which is convenient. The scavenge oil discharging path is arranged, which effectively increases lubricating properties for the bearing. The utility model can be used for three-phase asynchronous motors or other motors.
Description
(1) technical field: the utility model belongs to the auxiliary body of motor, is specially the oiling oil-releasing mechanism of bearing of motor.
(2) background technology: install bearing between shaft of motor and the end cap,, give the bearing oiling, to reduce friction when bearing operation arrives certain hour.In the prior art, no special bearing oil injecting machine structure will be opened the end cap of motor during oiling, unload lower ball cover again, gives the bearing oiling with oil can.This oiling mode is pretty troublesome, and does not have oil drain passage, and unnecessary waste oil can't be discharged, and reduces the greasy property of grease in the bearing.
(3) summary of the invention: the utility model provides a kind of oiling oil-releasing mechanism of bearing of motor at above-mentioned shortcoming, and it makes very convenient to oiling, the oil extraction of motor bearings, and grease does not have excessive.
The technical solution of the utility model is as follows: it is respectively equipped with oiling passage and oil drain passage in End cover for motor, the oiling passage is connected with the oiling chamber, the oiling chamber is connected with an end of bearing ball track, the other end of bearing ball track is connected with oil-discharging cavity, oil-discharging cavity is connected with oil drain passage, the end device plug cock of oil drain passage.
Owing to oiling pipeline, oiling chamber and oil-drain pipe, the oil-discharging cavity that is connected is set respectively at the two ends of bearing ball track, in the time will refueling,, oil is injected the oiling pipeline as long as take off the end socket of the oiling mouth of pipe to bearing, grease flows into the bearing track automatically.Behind the bearing operation certain hour, waste oil can be discharged from oil-discharging cavity and oil-drain pipe automatically.The utility model is extremely convenient to oiling, the oil extraction of bearing, and grease does not have excessive, avoids the pollution of leakage of oil to environment.
(4) description of drawings:
Fig. 1 is a structure chart of the present utility model.
(5) embodiment:
See Fig. 1, device bearing 7 between shaft of motor 8 and end cap 2, bearing cap 4 is chimeric with the inner face sealing of end cap 2.In electric motor end cap 2, process oiling passage 3 and oil drain passage 11 respectively, oiling passage 3 is connected with the annular oiling chamber 5 that is arranged in bearing cap 4, oiling chamber 5 is connected with an end of bearing ball track 6, the other end of bearing ball track 6 is connected with the oil-discharging cavity 9 that is arranged in electric motor end cap 2, between be added with sealing ring 10.Oil-discharging cavity 9 is connected with oil drain passage 11, the end device plug cock 12 of oil drain passage 11.
When wanting oiling, take off oil sealing head 1, oiling in the oiling passage 3.In the time will discharging waste oil, take off plug cock 12 and get final product.
Claims (1)
1, the oiling oil-releasing mechanism of bearing of motor, it is characterized in that in End cover for motor, being respectively equipped with oiling passage and oil drain passage, the oiling passage is connected with the oiling chamber, the oiling chamber is connected with an end of bearing ball track, the other end of bearing ball track is connected with oil-discharging cavity, oil-discharging cavity is connected with oil drain passage, the end device plug cock of oil drain passage.
