Is it feasible to use the gear reducer of the reducer?

Is it feasible to use the gear reducer of the reducer? The use of the gear reducer and the use of the reverse gear. It is assumed that the jade iron ore mine is a small and medium-sized underground mine. The main inclined shaft steel rope traction belt conveyor is used to transport the ore from the underground, and the actual amount of ore is increased every year. The arrangement of the 10,000-belt conveyor drive is shown in the figure. The gear reducer has been used since the year. The gears were inspected before being used for overturning. It was found that the contact spots of the low-speed shaft gears of the reducer were distributed over the entire tooth surface.

According to the regulations of the operation and maintenance of metallurgical mining equipment, this gear should be replaced by a mine machine according to the actual measurement, the gear wear is very small, the most serious pinion tooth root wear is far from the replacement of the standard steel rope traction tape delivery as specified in the regulations. The reducer of the machine is basically one-way operation. Therefore, although the tooth flanks on one side are covered with contact spots, the other side flanks are intact.

According to the above-mentioned condition of the reducer and the characteristics of use, combined with the analysis and research of the drawing materials, we envisage that although one side of the tooth surface can no longer be used, the other side of the tooth surface is intact, and the reducer is a double-row gear transmission, except for the low speed shaft. In addition to symmetry, the other parts are evenly symmetrical to the center line of the two rows of gears. The two reducers used at the same time are completely symmetrical to the center line of the belt conveyor. If the gears and shafts of the two reducers can be translated and replaced, Flip and use it to use the intact tooth surface on the other side, so that the steering of the motor is not changed or the direction of motion of the belt conveyor is changed. The geometric relationship analysis is correct.

This assumption should be feasible if force is allowed. Due to the presence of the wheel and the shoulder, the entire ring gear and gear are not axially displaced by the axial force.

For the two large gears on the shaft, since the axial force direction becomes outward, they are transmitted to the wheel by static fit, and the wheel is transmitted to the shaft by static cooperation. For the two large gears on the shaft, the direction of the axial force also becomes outward, because the spiral direction is opposite, such as the static fit between the ring gear and the wheel is sufficient to overcome the axial force and torque, then the two axial directions Force balances each other on the wheel.

Because the probability of getting the minimum static fit is very small, and for the sake of safety, all the torque that a single button can withstand is omitted. Therefore, theoretically, it is completely feasible to use the gear reducer of this reducer.

In the overhaul of the economic benefit practice verification year, month, month and day, the speed reducer was turned over based on the above assumptions and calculation results. After years of operation, the situation is good, which proves that the above assumptions and theoretical calculations are basically in line with reality.
