[0002] A speed reducer is an independent component consisting of gear drives, worm drives, or gear-worm drives enclosed in a rigid housing. It is commonly used as a speed reduction transmission device between a prime mover and a working machine. During the use of a speed reducer, in order to ensure its normal operation and extend its service life, it is necessary to periodically lubricate the gears and other components inside the speed reducer housing.

A fixing block is fixedly installed on one end of the upper surface of the placement plate, a column is fixedly installed on one end of the upper surface of the first fixing plate, a placement clamp is fixedly connected to the upper end of one side of the column, a second fixing plate is slidably installed on one end of the upper surface of the placement plate, and an adjustment component is fixedly installed on one end of the upper surface of the placement plate. However, in actual use, the above patent has the following drawback: when the oil injection device malfunctions, it is inconvenient for the user to remove it for repair. Therefore, we propose a quantitative oil injection device for a speed reducer housing. Utility Model Content

[0004] The purpose of this invention is to provide a quantitative oil injection device for a speed reducer housing to solve the problems mentioned in the background art.

[0008] Furthermore, the installation mechanism includes a limiting groove, a limiting block, a connecting plate, a stop bar, a second sliding groove, a second sliding column, a second sliding block, and a sleeve spring. Two limiting grooves are symmetrically opened on the top front side of the installation plate. The limiting grooves are T-shaped, and the limiting block is movably engaged inside the limiting groove.

[0009] Furthermore, the top of the limiting block penetrates the limiting groove and extends to the outside of the limiting groove, and is fixedly connected to a connecting plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, through the installation mechanism, allows the user to easily remove the oil injection component from the mounting plate for maintenance when a malfunction occurs. This is achieved by pulling down the stop bar to release it from the limiting block, simultaneously squeezing the sleeve spring, and then pulling the oil reservoir forward. This causes the connecting plate and the limiting block to move forward, disengaging the limiting block from the limiting groove. The oil injection component can then be removed from the mounting plate for maintenance. The operation is simple and convenient, greatly improving maintenance efficiency.

[0013] This utility model, by setting a sliding groove, a sliding column, and a sliding block, can adjust the position of the mounting plate, thereby adjusting the oil injection position of the oil injection component to adapt to the oil injection needs of different positions.

[0019] Please see Figure 1-6 The oil injection assembly 8 includes an oil reservoir 801, a metering pump 802, an oil suction pipe 803, an oil discharge hose 804, and a filling pipe 805. The bottom of the oil reservoir 801 is in movable contact with the top of the mounting plate 7. The metering pump 802 is fixedly connected to the top of the oil reservoir 801. The metering pump 802 is electromagnetically driven and the oil injection parameters can be set by the control system. By setting the metering pump 802, metered oil injection into the reducer housing can be achieved, avoiding waste of lubricating oil and ensuring the oil injection effect. The bottom of the metering pump 802 is fixedly connected to the oil suction pipe 803. The bottom of the oil suction pipe 803 passes through the oil reservoir 801 and extends into the interior of the oil reservoir 801. A filter screen is installed at the end of the oil suction pipe 803 to prevent impurities from entering the pump body.

[0021] In practical applications: When in use, place the reducer housing between the two clamping plates 3, and then use the electric push rod 2 to drive the clamping plates 3 to clamp the reducer housing. Then insert the oil drain hose 804 into the oil filling port of the reducer housing. When filling with oil, turn on the metering pump 802. The metering pump 802 draws out the lubricating oil in the oil storage tank 801 through the oil extraction pipe 803, and then delivers it to the oil filling port of the reducer housing through the oil drain hose 804 to achieve metered oil filling. When the lubricating oil in the oil reservoir 801 is insufficient, the valve on the refueling pipe 805 can be opened to replenish the lubricating oil in the oil reservoir 801 through the refueling pipe 805. When the oil injection component 8 malfunctions and needs to be repaired, the user only needs to pull down the stop bar 904 to release the stop bar 904 from the restriction of the limit block 902, and at the same time squeeze the sleeve spring 908, and then pull the oil reservoir 801 forward, which will drive the connecting plate 903 and the limit block 902 to move forward, thereby causing the limit block 902 to disengage from the limit groove 901, so that the oil injection component 8 can be removed from the mounting plate 7 for repair. The operation is simple and convenient, which greatly improves the repair efficiency.
