Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of motor bearing maintenance equipment, in particular to a device for adding grease to a motor bearing. Background Art
[0002] Motor bearings, also known as electric motor bearings or motor bearings, are special bearings specifically used in electric motors or motors. The bearing used in the motor is a part that supports the shaft. It can guide the rotation of the shaft and also withstand the idling parts on the shaft. The concept of bearings is very broad.
[0003] The existing motor bearing grease equipment has the following shortcomings:
[0004] The internal bearings of the motor are mainly distributed at the connection between the rotor and the housing. Due to the poor sealing of the front cover of the motor, the bearings at the front shaft end of the motor are easily dried up due to the influence of the external environment. Therefore, it is necessary to regularly add grease to the bearings to ensure the normal operation of the motor. The filling of grease for motor bearings with larger specifications requires the use of designated equipment, but most of the existing equipment adopts flat coating. Due to the high viscosity and poor fluidity of grease, this filling method makes the grease diffuse into the inside of the bearing slowly, causing most of the grease to remain on the outer surface of the bearing for a long time, resulting in poor filling effect and serious waste. Utility Model Content
[0005] The utility model changes the duration and quantity of the oil injection components, and can insert each oil injection pipe deeply between the corresponding two balls, so that the grease added subsequently can fully act on the inside of the bearing, thereby improving the grease utilization rate and reducing waste, thereby solving the problems raised by the above-mentioned background technology.
[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a device for greasing motor bearings, comprising an assembled outer cylinder, a group of support frames are welded to the outer wall of the assembled outer cylinder, an annular outer cover is fixedly installed between the outer walls of a group of the support frames, a group of visible feeding barrels are fixedly installed on the inner wall of the annular outer cover, a group of circular holes are opened on the front surface of the annular outer cover, and the number of circular holes in a group is equal to the number of visible feeding barrels, a positioning seat is fixedly installed inside each of the circular holes, a conveying pipe is fixedly inserted inside each of the positioning seats, the feeding end of each of the conveying pipes is respectively connected to the interior of a corresponding visible feeding barrel, a sealing ring is fixedly installed on the inner wall of each of the visible feeding barrels, and a piston is movably placed inside each of the sealing rings.
[0007] Preferably, an external frame is fixedly installed on the outer wall of each visual feeding barrel, a hollow sleeve is fixedly installed inside each external frame, a pneumatic push rod is fixedly inserted into the inner wall of each hollow sleeve, and the axial end of each pneumatic push rod is fixedly inserted into the inside of a corresponding piston.
[0008] Preferably, the outer wall of each of the visible material supply barrels is fixedly connected to a branch pipe, an electromagnetic valve is provided inside each of the branch pipes, and a booster is provided at the feed end of each of the branch pipes.
[0009] Preferably, a PLC controller is fixedly installed inside one of the support frames, and two groups of information lines are fixedly connected to the input end of the PLC controller, and the input ends of the two groups of information lines are connected to the internal wiring of the device.
[0010] Preferably, a limiting sleeve is fixedly installed on the outer wall of each conveying pipeline, a flow probe is fixedly inserted inside each limiting sleeve, and the sensing end of each flow probe is respectively placed inside a corresponding conveying pipeline, and a friction-increasing inner cylinder is fixedly installed on the inner wall of the assembly outer cylinder, and a group of friction-increasing strips are provided on the inner wall of the friction-increasing inner cylinder.
[0011] Preferably, a group of external frames are welded to the outer wall of the assembled outer cylinder, and a handrail is fixedly installed between the outer walls of the group of external frames.
[0012] Compared with the prior art, the advantages and positive effects of the utility model are:
[0013] In the utility model, after the friction-increasing inner cylinder is accurately inserted into the motor shaft end, a forward thrust can be applied at the end of the device to drive the device to move toward the front bearing of the motor until the front end of each conveying pipe is deeply inserted between every two balls. Then, each pneumatic push rod is turned on by the PLC controller, and its shaft end extends forward to apply a forward thrust to each piston. The grease inside the visible feed barrel flows into the conveying pipe under the spatial compression of the piston, and finally flows from the front end of the conveying pipe between every two balls. During the process, the flow probe will continuously contact the flowing grease and transmit the flow rate value within a period of time in the form of an electrical signal. The information is fed back to the PLC controller. At this time, the PLC controller obtains the amount of grease discharged per second according to the grease flow rate and the internal cross-sectional area of the conveying pipeline, and obtains the grease discharge time in each conveying pipeline in combination with the standard data. When the time is reached, each pneumatic push rod is shut down in turn. By changing the duration and number of the oil injection components, the equipment can insert each oil injection pipeline deeply between the corresponding two balls, so that the grease added subsequently can fully act on the inside of the bearing. At the same time, when the equipment is oiling, the grease discharge volume can be accurately calculated, and a standard amount of grease is strictly introduced into the shaft end, thereby avoiding waste caused by grease overflow.

[0022] like Figure 3 and Figure 4 As shown, an external frame 13 is fixedly installed on the outer wall of each visual feeding barrel 4, a hollow sleeve 14 is fixedly installed inside each external frame 13, a pneumatic push rod 15 is fixedly inserted into the inner wall of each hollow sleeve 14, and the axial end of each pneumatic push rod 15 is fixedly inserted inside a corresponding piston 12. By presetting the above components, pressure can be applied to the piston 12 to push forward, and the grease retained in the visual feeding barrel 4 can be squeezed to accelerate its outflow rate.
[0023] like Figure 1 and Figure 3 As shown, the outer wall of each visual feeding barrel 4 is fixedly connected to a branch pipe 8, an electromagnetic valve 9 is provided inside each branch pipe 8, and a booster 10 is provided at the feeding end of each branch pipe 8. By presetting the above components, the opening and closing of the internal channel of the branch pipe 8 can be limited, and the rate of introducing the raw materials into the visual feeding barrel 4 can be accelerated, thereby reducing the difficulty of raw material infusion.
[0024] like Figure 4 As shown, a PLC controller 18 is fixedly installed inside a support frame 2, and two groups of information lines 19 are fixedly connected to the input end of the PLC controller 18.

The grease inside the visible refill barrel 4 flows into the conveying pipe 7 under the spatial compression of the piston 12, and finally flows from the front end of the conveying pipe 7 into between every two balls. During the process, the flow probe 17 will continue to contact the flowing grease, and feed back the flow rate value within a period of time to the PLC controller 18 in the form of electrical signal information. At this time, the PLC controller 18 obtains the amount of grease discharged per second according to the grease flow rate and the internal cross-sectional area of the conveying pipe 7, and obtains the grease discharge time in each conveying pipe 7 by constructing standard data. When the time is reached, each pneumatic push rod 15 is shut down in turn, and each piston 12 is reset. The rear end adsorption force will retain the grease in the conveying pipe 7 and re-introduce it into the visible refill barrel 4.
