Adjustable balance differential

Abstract

The present application belongs to differential, and particularly relates to a regulating balance type differential. The regulating balance type differential comprises two corresponding half shafts, i.e. a left half shaft and a right half shaft, and the opposite positions of the two half shafts are provided with planetary gears. The significant effect of the present application is that the planetary gear set connected with one end of a winding drum (winding drum 1) is used as a power input to drive the two half shafts to move. The left half shaft is a virtual half shaft, which mainly plays a role in regulating the balance of the two half shafts, and the right half shaft is connected with another winding drum (winding drum 2). The relative movement of the left and right half shafts when the rotating speed is unbalanced is realized through the self-transmission of the power input planetary gears.

Description

Technical Field

[0001] This invention pertains to differentials, specifically to an adjustable balance differential. Background Technology

[0002] Current Status of Leaching Pump Pipeline Management in Uranium In-situ Leaching Mines: Currently, submersible pumps are commonly used in uranium in-situ leaching mines for leaching fluid extraction. These pumps consist of a pump body at the end, a discharge pipeline, and a power cable. Due to the considerable depth at which the submersible pumps are lowered and the substantial weight of the pump body and pipeline, mechanical devices are required to lift the pump after extraction. This process necessitates the retraction of both the discharge pipeline and the power cable.

[0003] Current mechanical cable winding devices are drum-type and electrically driven, which reduces labor costs to some extent, but can only wind up drainage pipes (with limited effectiveness); cable winding still requires manual labor. Winding up hundreds of meters of cable significantly increases the workload for workers. A device is needed that can simultaneously wind up drainage pipes and power cables, reducing the number of workers and their workload. However, due to the different diameters of the drainage pipes and power cables, it is difficult to balance the winding speeds, which is currently a major technical challenge preventing simultaneous winding. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing an adjustable balance differential.

[0005] The present invention is implemented as follows: an adjustable balance differential, comprising two corresponding half-shafts, namely a left half-shaft and a right half-shaft, with planetary gears arranged at opposite positions on the two half-shafts.

[0006] As described above, an adjustable balance differential is provided with a damping adjuster at the end of the left half-shaft.

[0007] As described above, an adjustable balance differential is provided with a power input section located around the left half-shaft.

[0008] As described above, an adjustable balance differential is provided with a drive gear in the power input section.

[0009] As described above, in an adjustable balance differential, one end of the right half-shaft is a bevel gear, which together with the power input part forms a differential, and the other end is connected to the drum 2.

[0010] As described above, in an adjustable balance differential, the left half-shaft is a virtual half-shaft, with a bevel gear at one end, which also forms a differential with the power input part, and the other end is connected to a damping adjuster.

[0011] As described above, in an adjustable balance differential, the power input section consists of two planetary gears, an upper and a lower one, a transmission sleeve connected thereto, and an end parallel shaft gear.

[0012] The significant advantage of this invention is that it utilizes an adjustable balance differential to take the planetary gear set connected to one end of the drum (drum 1) as the power input, driving the two half-shafts to move. The left half-shaft is a virtual half-shaft, mainly used to adjust the balance between the two half-shafts, while the right half-shaft is connected to another drum (drum 2). The left and right half-shafts achieve relative movement when their speeds are unbalanced through the self-rotation of the planetary gears in the power input section. Attached Figure Description

[0017] The present invention relates to the development of a special connecting device that adjusts the imbalance in the rotational speeds of the half-shafts connected to its two ends using the differential principle; hence, it is called an adjusting balance differential. The adjusting balance differential consists of the following parts (see attached diagram). Figure 1 ):

[0018] 1. Two half-shafts, left and right. One end of the right half-shaft is a bevel gear, which forms a differential with the power input part, and the other end is connected to the drum 2. The left half-shaft is a virtual half-shaft, with a bevel gear at one end, which also forms a differential with the power input part, and the other end is connected to the damping adjuster;

[0019] 2. The power input section consists of two planetary gears (which can rotate on their own), a transmission sleeve connected to them, and an end parallel shaft gear;

[0020] 3. Damping adjuster, mainly used to adjust the running resistance of the half-shaft. This is achieved by adjusting the speed of the left half-shaft.

[0021] The purpose of the right half-shaft rotation speed.

[0022] The device's right half-shaft and power input section are connected to two receiving drums (used for cable storage), while the left half-shaft is a virtual half-shaft (separated from the power input section by two bearings, allowing relative movement between them). The device primarily achieves power output to the right half-shaft by adjusting the resistance of the left half-shaft, which is accomplished through a damping adjuster connected to the left half-shaft. The drum rotation speed can be categorized into three cases: one where both drums operate synchronously; another where the right drum's rotation speed is momentarily lower than the left drum's during pump lifting; and a third where the right drum's rotation speed is momentarily lower than the left drum's during pump lowering. Based on the drum rotation requirements, the tachometer operates under these three conditions.

[0023] 1. When the resistance of the left and right half-shafts is the same, the rotational speed of the right half-shaft is the same as the rotational speed of the power unit, and the rotational speeds of the two drums connected to it are also the same. Under this condition, the resistance of the left half-shaft must not be too high. If the resistance is too high, the power of the right half-shaft will be too high. When condition 2 occurs, it is easy to damage the pipeline that needs to be stored.

[0024] 2. During pump lifting, when the instantaneous speed of the right half-shaft needs to be lower than that of the power unit, the resistance of the right half-shaft is greater than that of the left half-shaft. The speed difference between the two shafts is offset by the self-rotation of the two planetary gears of the power unit (see appendix). Figure 2 ).

[0025] 3. During the pump lowering process, reduce the resistance of the left half-shaft. At this time, the resistance of the right half-shaft is greater than that of the left half-shaft. When the power unit is running, the left half-shaft moves, and the right half-shaft is lowered together with the power unit through pipeline traction. The relative movement of the left and right half-shafts is canceled out by the self-rotation of the planetary gears in the differential. At this time, the planetary gears are in a free state (see appendix). Figure 3 ).
