Common problems of spiral bevel gear reducer

1. Slurry leakage at the shaft end, bearing damage, stirring blades, broken and loose liners, broken wire ropes, knotted, track deformation damage, pulley damage, various load-bearing parts damage, etc. The reasons are as follows: ① human factors. Operators did not maintain the equipment in time, and the faults accumulated from small to large, resulting in irreparable damage to parts. ②The wearing parts are damaged. The wearing parts were not replaced in time. Solution ① Establish a mechanical maintenance system. Establish a sound mechanical maintenance system, divided into planned maintenance system and preventive maintenance system, focusing on maintenance and prevention. ②Measures to deal with parts prone to wear. The wear parts are mainly from the three directions of the liner plate and the shaft end seal of the wire rope.

2. The pressure of the hydraulic system is insufficient, the oil temperature is too high, the hydraulic oil is polluted, the flow pulsation is large, the noise is serious, the reversing valve does not respond, and the pipeline leaks. The reason is that there are many reasons why a hydraulic system fails, because there is more than one control element. Solution: ① When the pressure is insufficient, there is often a problem with the hydraulic pump, and the hydraulic pump needs to be overhauled. ② Adjustment is required when the steering is inaccurate. ③When the speed is too low, it is necessary to increase the speed. ④ When the viscosity of the hydraulic oil is not enough, the standard hydraulic oil needs to be replaced, and the hydraulic oil should be selected according to the temperature of the construction workshop. ⑤ When the overflow valve leaks, it should be replaced in time.

Second, the spiral bevel gear reducer circuit failure

1. The motor is damaged, the insurance burns, the control transformer burns, and the regular water supply function fails. The reason is that the circuit failure problem is caused by the circuit itself. Solution: The circuit is broken or the device is short-circuited. Check whether the circuit connection is correct. If not, replace the correct circuit. If the circuit is short-circuited, replace the circuit. The above are the common faults and solutions of concrete reactor reducer
