A rapid maintenance slip ring external acceleration turntable

Abstract

The invention relates to a quick repairing slip ring external acceleration turntable. The quick repairing slip ring external acceleration turntable comprises a drive motor, a reducer connected to theoutput shaft of the drive motor, a rotary table connected to the output shaft of the reducer and a conductive slip ring connected to the outside; the output shaft of the reducer and the rotating tableare connected by an oil guiding ring; and the oil guiding ring is located at the outer side of the reducer, and the oil guiding ring is arranged at the outer side of the reducer. When the oil guidingring leaks oil, the condition of oil leakage can be found in time to avoid cross contamination of the hydraulic oil and a gear. Besides, the maintenance of the oil guiding ring does not need to remove the entire reducer casing; the oil guiding ring has its own independent bearing support system, a rotor is connected to the output shaft of the reducer casing, a stator is connected to the reducer casing housing, the stator of the oil guiding ring and stator holding sleeve are fixed by employing a pair of bolt angles, sufficient clearance is left in the circumferential direction, so that the oilguiding ring is relatively ideal in stress, and the oil guiding ring has a long service life.

Description

technical field [0001] The invention belongs to the field of acceleration turntables, in particular to a quick-maintenance slip ring external acceleration turntable. Background technique [0002] Acceleration turntables currently on the market such as figure 1 As shown, it is installed in the foundation pit. The motor at the bottom drives the reducer and then the turntable rotates. The test piece is fixed on the turntable. When the turntable is in use, it needs some external necessary connections such as electrical signals and transmission actions. The top of the turntable is the electric The slip ring is used to unblock the electric power and the electric signal, and the hydraulic connection is connected through the transmission shaft. The hydraulic pipe enters the reducer through the side wall of the reducer box, and the slip ring is installed in the reducer, and then it is completed through the drive shaft and the rotary table. Unicom. The current acceleration turntable...

Problems solved by technology

However, the maintainability is extremely poor. Once the oil guide ring leaks, it will cause the hydraulic oil and gear oil to mix and fill the gearbox. In addition to causing the oil to be scrapped, the maintenance needs to disassemble the entire reducer, and then check the oil guide ring. Daily If you want to know the working status of the oil guide ring, you can only judge by the oil volume of the hydraulic system. In this way, it will only appear when the oil guide ring is seriously damaged. At that time, there will be four hazards

[0004] One is that the gear oil deteriorates, and the increase in the amount of oil will increase the number of internal teeth in the reducer, which is fatal to the entire power system

[0005] Second, hydraulic oil leakage will limit the working limit of the hydraulic system, and it is very easy to fail to meet the experimental requirements.

[0006] The third is to affect the stability of the turntable. Once the slip ring is damaged and cannot be eliminated in time, it will have a fatal impact on the stability of the high-speed rotating turntable, and the high-precision and high-speed experiments cannot be completed stably.

[0007] Fourth, the maintenance is extremely inconvenient. Even to check the oil guide ring, the reduction box must be disassembled. As for the maintenance, it is also very difficult.
