Description

Technical Field

[0001] This utility model belongs to the field of zinc processing technology, and in particular relates to a spiral bevel reducer for zinc processing. Background Technology

[0002] Zinc is an important non-ferrous metal, widely used in industry, metallurgy, battery manufacturing, corrosion protection and other fields. In the zinc processing and production process, the spiral bevel gear reducer is one of the most important pieces of equipment, used to realize the transmission and speed reduction between two structures or devices. It is mainly composed of a housing, a gear transmission system and a bearing support system.

[0003] A spiral bevel gear reducer is disclosed in the existing authorized announcement document CN221704402U, including a base and a reducer body. The upper surface of the base has a fixing groove near the four corners. A support column is installed at the bottom of the fixing groove. The reducer body is installed on the upper surface of the support column. Connecting frames are symmetrically installed on the left and right side walls of the base. A fixed fan is installed on the upper surface of the connecting frame. An air outlet pipe is installed at the bottom of the fixed fan. The bottom of the air outlet pipe is installed on the upper surface of the reducer body. An air outlet is opened on the left end face of the reducer body. A cover plate is installed in the air outlet by snap-fit.

[0004] However, it still has the following drawbacks in practical use:

[0005] 1. The spiral bevel gear reducer mentioned above uses internal bevel gears for transmission and speed reduction. However, during use, its transmission reduction ratio is fixed. Changing the transmission reduction ratio requires replacing the bevel gears, which is quite cumbersome. In the zinc processing process, due to the different speed requirements of multiple processes, multiple models of reducers are needed, resulting in a small range of applications and low practicality.

[0006] 2. The spiral bevel gear reducer mentioned above uses internal bevel gears for transmission and speed reduction. However, in order to avoid wear of the bevel gears during use, they need to be lubricated regularly. However, the existing reducers lack an automatic lubrication structure, which means that manual lubrication is required. Furthermore, since the bevel gears are sealed inside the reducer, the workload of lubrication is further increased.

[0007] To address these issues, we provide a spiral bevel gear reducer for zinc processing. Utility Model Content

[0008] The purpose of this utility model is to provide a spiral bevel reducer for zinc processing. By using a mounting frame and a moving block to drive the output shaft to connect with different connecting rods, the output speed can be controlled, thus solving the problem of inconvenient adjustment of the reduction ratio in existing models. At the same time, by using a second threaded rod and a distributor to drive the lubrication nozzle to move, the lubrication nozzle lubricates the gears inside the housing, thus solving the problem of inconvenient automatic lubrication of gears in existing models.

[0009] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

Fixing frames are fixedly connected to both sides of the front end face of the mounting plate, and mounting frames are movably connected between adjacent fixing frames. The frame is internally connected to a movable block, and an output shaft is rotatably connected to the movable block. The rear end of the output shaft is engaged with the front end of one of the connecting rods. A lubrication assembly is also provided on the upper inner side of the box. The lubrication assembly includes a second threaded rod rotatably connected to the front and rear ends of the upper inner side of the box and a guide block that passes through one side of the top of the box. A second slider is threadedly connected to the second threaded rod. A distributor is fixedly connected between adjacent second sliders. Multiple liquid outlets of the distributor are fixedly connected to lubrication nozzles. The liquid inlet of the distributor is connected to the liquid outlet of the guide block through a telescopic joint. A lubricating oil cylinder is fixedly connected to the top of the guide block.

[0011] A further feature of this invention is that the front end of each connecting rod is fixedly connected to a first retaining plate, and the rear end of the output shaft is fixedly connected to a second retaining plate that cooperates with the first retaining plate.

[0012] A further feature of this invention is that the front end face of the first card plate is provided with positioning holes around all four sides, and the rear end face of the second card plate is provided with positioning posts that mate with the positioning holes around all four sides.

[0013] A further feature of this invention is that a first threaded rod is rotatably connected inside the fixed frame, the front end of the first threaded rod extends to the front of the outer side of the fixed frame and is fixedly connected to a knob, a first slider is threadedly connected to the outer wall of the first threaded rod, and one end of the first slider located outside the fixed frame is fixedly connected to the outer walls of both sides of the mounting frame.

[0014] A further feature of this invention is that: the top and bottom of the mounting frame are provided with through grooves, and a fixing rod passes through the inside of the through grooves. One end of the fixing rod is fixedly connected to both sides of the top and bottom of the movable block, and the other end of the fixing rod is threaded with a fastening nut. The fastening nut is respectively attached to the top and bottom of the mounting frame.

[0015] A further feature of this invention is that a motor is fixedly connected to the upper part of one side of the outer wall of the housing via a mounting bracket, and the output shaft of the motor extends to the inner side of the housing and is fixedly connected to one end of one of the second threaded rods.

[0016] A further feature of this invention is that the other end of the second threaded rod extends to the outside of the housing and is fixedly connected to a synchronous pulley, which is connected to the other end by a synchronous belt drive.

[0017] A further feature of this invention is that an electric push rod is fixedly connected to the top of the lubricating oil cylinder, and the output shaft of the electric push rod extends to the upper inner side of the lubricating oil cylinder and is fixedly connected to a pressure plate.

[0018] This utility model has the following beneficial effects:

[0019] 1.

Loosening the fastening nut allows the moving block to move the output shaft in the left-right direction. When the moving block moves the output shaft to a designated position in the left-right direction, tightening the fastening nut allows the output shaft to connect with the new connecting rod. This facilitates the adjustment of the reduction ratio between the input and output shafts, making it suitable for use in different zinc processing procedures, expanding its applicability and improving its practicality.

[0020] 2. This utility model, by setting up a lubrication component, starts the motor, which drives the second slider and the distributor to move inside the housing via the second threaded rod. When the distributor and the lubrication nozzle move to the designated position, the motor is turned off and the electric push rod is activated. The electric push rod and the pressure plate guide the lubricating oil in the lubricating oil cylinder into the distributor through the guide block and the telescopic joint, and finally spray it onto the gear through the lubrication nozzle. This facilitates automatic lubrication of the gear and reduces the workload of the workers. Attached Figure Description
