Description

Technical Field

[0001] The invention relates to the technical field of planetary reducers, and in particular to a planetary reducer capable of bearing impact loads. Background Art

[0002] Planetary reducers are widely used industrial products that can reduce the speed of motors while increasing output torque. Planetary reducers can be used as supporting components in industries such as lifting, excavation, transportation, and construction.

[0003] At present, the existing planetary reducer needs to add lubricating oil to its interior after being used for a period of time. Usually, the lubricating oil is added by disassembling and applying the lubricating oil to make the internal gears evenly attached, but this method is relatively cumbersome. Secondly, the existing planetary reducer will cause a certain impact load due to the effect of inertia at the moment of receiving power transmission, thereby causing mechanical damage, which is not conducive to the long-term use of the planetary reducer. Summary of the invention

[0007] As a preferred technical solution of the present invention, the impact-resistant component includes an outer cylinder, one end of the input shaft is connected to the outer cylinder, the inner part of the outer cylinder is movably connected with an inner shaft, and one end of the inner shaft is interlaced and connected with the center position of one side of the oil collecting plate.

[0008] As a preferred technical solution of the present invention, a movable cavity is provided at the connection between the outer cylinder and the inner shaft, a spring is provided inside the movable cavity, and two ends of the spring are respectively connected to one side of the outer cylinder and the inner shaft.

[0009] As a preferred technical solution of the present invention, one end of the three driven gears is rotatably connected to a tripod bracket, a clamping block is installed at the center of the tripod bracket, and one end of the clamping block is clamped and connected to the output shaft.

[0010] As a preferred technical solution of the present invention, a shell cover is provided on one side of the shell, and the shell cover includes a cover plate, a circular hole is opened at the center of the cover plate, and one end of the output shaft passes through the circular hole and extends to the outside of the shell cover.

[0011] As a preferred technical solution of the present invention, the outer wall edge of the shell cover is threadedly connected with bolts, and the shell cover is connected to one side of the outer shell through the bolts.

[0012] As a preferred technical solution of the present invention, the shell is provided with a fixing plate on a side away from the shell cover, the fixing plate comprises a plate, the plate is welded to the outer wall of the shell, and the outer wall of the plate is respectively provided with perforations at four corners.

[0013] As a preferred technical solution of the present invention, one end of the input shaft passes through the center of the plate and extends to the outside of the housing.

[0014] As a preferred technical solution of the present invention, the arc-shaped oil pipe is located directly above the outer gear ring and the oil collecting plate.

[0015] As a preferred technical solution of the present invention, the inner thread of the square box is connected with an oil plug.

[0016] On the other hand, the present invention provides a method for using a planetary reducer capable of bearing an impact load, comprising the following steps: Step 1: First, the input shaft of the planetary reducer is connected to the driving device, so that the rotational torque on the input shaft is directly transmitted to the anti-shock component, wherein the outer cylinder is driven to rotate by the input shaft, so that the outer cylinder squeezes the spring in the movable cavity, and the other end of the spring is driven to rotate by the compression deformation to the limit, until the rotational mechanical energy is transmitted to the planetary gear assembly; Step 2: Apply torque to the oil collecting plate through the inner shaft, so that the oil collecting plate drives the shaft pile to rotate and promotes the driving gear to rotate. Then, through the meshing connection between the three driven gears and the driving gear, the three driven gears rotate around the driving gear inside the outer gear ring, thereby driving the three-pronged bracket between the three driven gears to rotate at a low speed; Step three: dock the output shaft with the tripod bracket through the clamping block, so that the output shaft in the planetary reducer maintains a low-speed rotating power output. After the reduction output is completed, the oil plug can be twisted to open the square box, and lubricating oil is injected into the interior of the square box. The lubricating oil flows to different directions through the diversion effect of the arc-shaped oil pipe, and drips onto the planetary gear assembly along the oil hole. The positional relationship between the oil collecting plate and the oil hole allows the dripping lubricating oil to be gathered at the connection between the driven gear and the driving gear through the diversion effect of the oil collecting plate, thereby achieving lubrication between the gears.

[0017] Compared with the prior art, the present invention has the following beneficial effects: By arranging an oil injection mechanism inside the opening, the planetary reducer can directly realize the function of adding lubricating oil, effectively reducing the complicated disassembly and assembly process. Through the connection between the square box and the arc-shaped oil pipe, the arc-shaped oil pipe can guide the lubricating oil to different directions and drip along the oil hole to different positions in the planetary gear assembly, thereby realizing the lubrication function between the internal gears of the planetary reducer; Secondly, by adding an anti-impact component between the planetary gear assembly and the input shaft, the impact generated at the moment of starting the planetary reducer can be effectively mitigated. By setting a movable cavity between the outer cylinder and the inner shaft, a space is provided for the placement of the spring, so that the impact force of the rotation of the outer cylinder can be offset and weakened by the elastic action of the spring, and the torsional impact on the inner shaft can be reduced. At the same time, it plays a protective role on various internal structures of the planetary gear assembly. BRIEF DESCRIPTION OF THE DRAWINGS
