Description

Technical Field

[0001] The utility model relates to the technical field of mechanical manufacturing, and particularly relates to an automatic grease filling and equalizing device for locomotive bearings. Background Art

[0002] At present, the workload of locomotive bearing maintenance is very large. Especially in terms of bearing grease filling, most of it is manually filled with a grease gun. Before grease filling, the bearing is weighed first, and then weighed again after grease filling. The difference between the two weighings is the grease filling weight, and it is qualified within the range of the required grease filling weight specified by the process. Due to manual grease filling, it is necessary to weigh repeatedly and refill grease repeatedly to ensure that the grease filling amount is within the required range. The workload is relatively large and the efficiency is low. Moreover, the locomotive bearing weighs about 10 kilograms, and repeated picking up and placing also results in a relatively large labor intensity. Content of the Utility Model

[0003] The utility model designs an automatic grease filling and equalizing device for locomotive bearings to solve the above-mentioned existing problems.

[0004] In order to achieve the above technical purpose and reach the above technical effect, the utility model is realized by the following technical solutions:

[0005] An automatic grease filling and equalizing device for locomotive bearings includes a base. On the left side of the top wall of the base, there is a bottom plate. On the top wall of the bottom plate, there are multiple load cells. Between the top walls of the multiple load cells, there is a support plate. On the top wall of the support plate, there is a motor one. At the top of the output main shaft of the motor one, there is a top seat. In the middle of the top wall of the top seat, there is a top plate. On both sides of the top wall of the top seat, there are cylinders. At the inner end of the drive of the cylinder, there is a clamping seat;

[0006] On the right side of the top wall of the base, there is a support column. At the top of the left side wall of the support column, there is a support seat. On the outer wall of the support seat, there is a hydraulic telescopic rod. At the bottom of the drive of the hydraulic telescopic rod, there is a grease filling mechanism.

[0007] Further, the grease filling mechanism includes a housing. On the left side of the inner wall of the housing, there is a motor two. The output end of the motor two is locked with a lead screw through a coupling, and the other end of the lead screw is rotationally connected to the inner wall of the housing through a bearing. A pair of connecting blocks are threadedly connected to the outer wall of the lead screw. On the bottom wall of the connecting block, there is a connecting rod. The bottom wall of the connecting rod extends out of the housing and is provided with a grease filling head. Between the outer walls of the connecting rods, there is a connecting pipe. One end of a liquid inlet pipe is provided on the outer wall of the connecting pipe.

[0008] Further, the lead screw is a bidirectional lead screw, and the pair of connecting blocks are threadedly connected to the threads with different helix directions on the outer wall of the lead screw.

[0009] Furthermore, the outer ring of the bearing is fixedly connected to the inner wall of the housing through the bearing seat, and the inner ring of the bearing is interference-fitted with the outer wall of the lead screw.

[0010] Furthermore, the weighing sensors are arranged in a circular pattern at equal intervals between the base plate and the support plate.

[0011] The beneficial effects of this utility model are:

[0012] This invention uses a weighing sensor to weigh the bearing and grease in real time. When the set weight value is reached, the grease injection operation can be stopped automatically, avoiding tedious and repetitive operation procedures. This effectively reduces the number of weighing and grease replenishment times during the grease injection process, thereby significantly improving the overall efficiency of locomotive bearing grease injection.

[0013] This invention uses a cylinder to drive the clamping seat to hold and fix the bearing. During the grease injection process, each component is driven by a motor, hydraulic telescopic rod, etc. to perform corresponding actions to complete the grease injection and even grease distribution operation. This eliminates the need for frequent manual removal and placement of the bearing, greatly reducing the labor intensity of the operators.

[0014] By utilizing the real-time weighing function of the load cell, the total weight of the bearing and grease can be accurately monitored during the grease injection process. This allows for strict control of the grease injection amount, ensuring that the bearing grease injection amount accurately reaches the set weight value. This effectively guarantees that the grease injection amount is within the process requirements, improving the quality and accuracy of the grease injection process in locomotive bearing maintenance.

[0015] The second motor drives the lead screw to rotate, which in turn moves the connecting block, connecting rod, and grease injection head. The position of the grease injection head can be flexibly adjusted according to the different diameters and lengths of the bearings, making it more adaptable to various specifications of locomotive bearings and enhancing the versatility and applicability of the device in practical applications.
