ZF PLM 9 Reducer Construction Machinery Spare Parts Hydraulic Motor And Gearbox

Product detail:

The reducer plays a role in matching the speed and transmitting torque between the prime mover bai and the working machine or the actuator du. The reducer is a relatively precise machine. The purpose of using zhuan is to reduce the speed and increase the torque.

ZF mixer reducer PLM7, PLM9, P3301, P4300, P5300, P7300, P7500 high-power mixer reducer to meet the different needs of customers to provide more selectivity, RTR developed and launched P series high-power mixer reducer, To meet the concrete mixer maximum drum mixing capacity of 12m3 performance requirements. The P-series mixer reducer consists of a basic two-stage planetary gearbox and is driven by a standard SAE flanged hydraulic motor. The P-Series also offers advanced technology and economy, reliable operation, low maintenance and wear Even running under extreme conditions is equally good.

Maintenance:

1. Pump truck rotary reducers are all upright on the lower rotary table.

2. The rotary reducer is equipped with dustproof enclosure.

3. From the structure of the reducer, only a skeleton oil seal is installed on the output shaft on the vertical surface of the rotary reducer.

4. There must be a gap due to relative movement when turning up and down.

5. The construction environment of the pump truck is poor, and sometimes the concrete pipe will be exploded during work, which will easily cause the mortar to fall into the rotating enclosure.

6. It is inconvenient for users to discover the condition of the reducer hidden in the enclosure.

As long as the skeleton oil seal is protected from damage, the reducer will not be broken. If you want to prevent mortar from entering the reducer, such as changing the material of the dust-proof enclosure, using hard plastic or soft rubber to make professional matching protective abrasives, the sealing and dust-proofing is obviously unrealistic.

Use butter or base grease to smear a thick layer on the circumference of the rotating pinion. If it is convenient to remove the rotating pinion later, you can also put a layer on the upper end of the rotating pinion, or fill the pinion (with back The encoder can be wiped less).

1. Change the butter once every six months.

2. It is recommended to grease the rotary reducer of the new car in the debugging department before leaving the factory.
