Abstract

The utility model relates to an automatic motor oil releasing and discharging device, which comprises a bearing outer cover, an oil releasing and discharging passage, a spherical valve and a spring. A hole is arranged on the bearing outer cover, the upper portion of the oil releasing and discharging passage is connected with the bearing outer cover via the hole, the spring is arranged on the lower portion of the oil releasing and discharging passage, and the spherical valve is arranged on the top of the spring. Compared with the prior art, an automatic motor oil discharging mechanism uses oil pressure to adjust a gap between the spherical valve and the oil releasing and discharging oil passage to discharge waste oil, so that new oil is injected into a bearing and simultaneously the waste oil is sequentially discharged, and the automatic motor oil releasing and discharging device greatly improves work efficiency. Additionally, the automatic motor oil discharging mechanism with fewer parts and the oil releasing and discharging passage capable of being connected with the bearing in a threaded manner are convenient in maintenance due to the fact that the oil releasing and discharging passage can be rotated to be detached when the spherical valve or the spring inside the passage needs to be replaced.

Description

A kind of motor is let out discharge equipment automatically
Technical field
The present invention relates to a kind of discharge equipment of letting out automatically, especially relate to a kind of motor and let out discharge equipment automatically.
Background technology
The domestic electric machine industry is united the Y2 of unified design at present; Y3 serial motors and YB; though having, YB2 series fire-proof motor bearing lubrication system do not shut down refueling device; but not having bearing lubrication system lets out the oil extraction function automatically and all needs the artificial cover plate of manually removing discharge equipment earlier just can discharge lubricating oil; extremely inconvenient in the actual use of user; limited by the coupled position of supporting machinery equipment; and can't before refueling, remove the cover plate of discharge equipment earlier; thereby original dirty oil or outmoded oil are discharged along outage; can only be under the pressure effect of nozzle; connect the position from bearing of motor inner cap axle and infiltrate into the motor stator winding inner chamber, and then cause that the quality accident that motor windings is burnt takes place frequently.
Summary of the invention
The purpose of this utility model just provide a kind of simple in structure, easy to use, just let out discharge equipment automatically with the motor of installation and maintenance.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of motor is let out discharge equipment automatically, this device is installed on the bearing of motor lower curtate, comprise bearing end cover, let out oil drain passage body, globe valve and spring body, have hole on the described bearing end cover, the described oil drain passage body top of letting out links to each other with bearing end cover by hole, this is let out in the oil drain passage body spring body is set, and described spherical valve is arranged on the top of spring body.
The described oil drain passage body of letting out is that fine thread is connected with bearing end cover.
Described spring body is the spring of adjustable pressure.
Compared with prior art, the utlity model has following advantage: because motor automatic oil draining mechanism utilizes oil pressure to regulate ball valve and the gap of letting out oil drain passage to get rid of waste oil, so waste oil is also got rid of immediately when injecting fresh oil in bearing, has improved operating efficiency greatly; Motor automatic oil draining mechanism components is less and let out oil drain passage and can be threaded with bearing, when ball valve in needs are changed passage or spring body, only needs a knob to let out oil drain passage and it can be pulled down convenient for maintaining.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation that motor of the present utility model is installed.
1 for let out oil drain passage body, 13 for spherical valve, 14 is spring body for bearing end cover, 12 for letting out discharge equipment, 2 automatically for motor, 11 among the figure.
Embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
Embodiment
A kind of motor is let out discharge equipment 1 automatically, as shown in Figure 1, this device is arranged at motor 2 bottoms, its structure as shown in Figure 2, this device comprises bearing end cover 11, lets out oil drain passage body 12, globe valve 13 and spring body 14, have hole on the bearing end cover 11, letting out oil drain passage body 12 tops links to each other with bearing end cover 11 by hole, this is let out oil drain passage body 12 and is connected for fine thread with bearing end cover 11, let out spring body 14 is set in the oil drain passage body 12, spring body 14 is the spring of adjustable pressure, and spherical valve 13 is arranged on the top of spring body 14.
When motor injects new oil, the bearing internal oil pressure increases, waste lubricating oil is let out in the oil drain passage body 2 by the inflow of the hole on the bearing end cover 11 and is pushed spherical valve 3, globe valve 13 stressed back extrusion spring bodies 14, make spring body 14 deformation compression, and pulling spherical valve 13 is to bottom offset, waste lubricating oil is drained oily passage 12 along with spherical valve 13 and the slit of letting out oil drain passage body 12 flow into, discharge outside the body by the following hole of letting out oil drain passage body 12, when finding the basic emptying of waste lubricating oil, stop to refuel, along with the bearing internal pressure reduces, spring body 14 resets and promotes ball valve 13 and resets lubricating oil is no longer discharged.
In order to satisfy under the different operating environment to lubricated requirement, spring body 14 all right regulating spring pressure, make its can be in the various environment of high and low temperature operating stably, adopt fine thread to be connected owing to let out oil drain passage body 12 with bearing end cover 11, when needs are changed ball valve 13 or regulating spring body 14, only need to let out the discharge equipment knob automatically and following getting final product.
Bearing end cover 11 adopts metal material, and the trade mark is HT150 or HT200, lets out oil drain passage body 12 and can adopt metal or nonmetallic materials, and spring body 13 adopts metal material, and spherical valve 14 adopts metal material, and it is more durable to make motor let out discharge equipment automatically.
