Technical Field
The utility model belongs to the technical field of explosion proof machine's bearing configuration and lubricating structure, concretely relates to explosion proof machine's notes oil extraction structure.
Background
The existing explosion-proof motor is a motor with a central height of H132 or below, and a closed bearing is always adopted; the center height H160-225 is the position of the oil injection and discharge device which is structurally considered, and the motor with the center height H250 and above is provided with the oil injection and discharge device. The motor with the height H132 and below the center is not provided with an oil injection and discharge device, and the position of the oil injection and discharge device is not provided, so that oil injection cannot be carried out at all. Moreover, because the center height H132 and the size of the lower explosion-proof motor are small, the size of the motor C is smaller, and the oil injection and discharge position cannot be set through simple design change, so that the oil injection and discharge function cannot be achieved. Because explosion-proof motors relate to safety, nowadays, safety is increasingly emphasized, and ensuring safe operation of the motors is particularly important. And the reasonable setting of the explosion-proof surface is ensured on the premise of setting the oil injection and discharge structure under the central height H132.
Disclosure of Invention
The utility model aims at overcoming above-mentioned weak point, providing an effectual notes oil extraction structure, this structure has solved the problem that H132 and following explosion proof machine can't annotate the oil extraction among the existing technology, and effectually lubricates and maintains antifriction bearing.
In order to solve the technical problem, the utility model discloses a following technical scheme solves: concretely, explosion proof machine's notes oil extraction structure, characterized by: the device comprises a transmission shaft, a sealing oil seal, a bearing outer cover, a rolling bearing, an oil cup, a shell and an end cover;
the bearing outer cover and the end cover sequentially penetrate through the transmission shaft, the end cover is installed on the shell and provided with an oil filling hole, an oil discharging hole is formed in the end cover in the radial direction corresponding to the oil filling hole, and oil cups are arranged at the ports of the oil filling hole and the oil discharging hole to seal the ports;
the rolling bearing is tightly assembled in a bearing chamber of the end cover.
Furthermore, the oil filler point and the oil drain hole that set up on the end cover be screw hole and through-hole complex structure, set up the end cover oil storage tank bottom the end cover bearing chamber, the end cover sets up the flame proof face composition surface with the transmission shaft cooperation, and this flame proof face composition surface sets up at antifriction bearing inboard.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the following will describe in further detail common embodiments of the present invention with reference to the accompanying drawings.
In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.
In addition, in the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.
As shown in fig. 1-2: the utility model provides an explosion proof machine's notes oil extraction structure which characterized by: the device comprises a transmission shaft 1, a sealing oil seal 2, a bearing outer cover 4, a rolling bearing 5, an oil cup 6, a machine shell 7 and an end cover 8;
the bearing outer cover 4 and the end cover 8 sequentially penetrate through the transmission shaft 1, the end cover 8 is installed on the machine shell 7, an oil filling hole 8.1 is formed in the end cover 8, an oil discharging hole 8.2 is formed in the end cover corresponding to the oil filling hole 8.1 in the radial direction, and oil cups 6 are arranged at the ports of the oil filling hole and the oil discharging hole to seal the ports;
the rolling bearing 5 is tightly fitted in a bearing chamber of an end cap 8. The rolling bearing 5 is an open rolling bearing.
And the bearing outer cover 4 is provided with an outer cover oil storage tank 4.1 and a mounting hole for mounting the counter bore bolt 3. And a sealing oil seal 2 is arranged on the bearing outer cover 4.
The working process is as follows: after an oil cup 6 above an end cover 8 is removed, grease is injected along an oil injection hole 8.1 of the end cover 8 and flows into an end cover oil storage tank 8.3 along an oil groove hole on a bearing chamber cavity of the end cover 8, when a motor operates, the grease enters a rolling bearing 5 from the end cover oil storage tank 8.3 for lubrication, after operation, waste grease flows out of the rolling bearing 5 and is collected into an outer cover oil storage tank 4.1 and then enters an oil discharge hole 8.2 of the end cover 8, and after the oil cup 6 below the end cover 8 is removed, the waste grease is discharged along the oil discharge hole 8.2.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention in any way. Any simple modification, change and equivalent changes made to the above embodiments according to the utility model all still belong to the protection scope of the technical scheme of the utility model.
