The roller line reducer usually causes this symmetrical internal structure, the main reason, is because this kind of goods in the case of adoption, it must be able to operate and rotate. And if it wants to carry out the same rotation, it is necessary to construct a part of symmetry in the internal structure as far as possible, or it is only like the hydraulic pump that only carries out positive rotation, but cannot carry out rotation.

Is due to the use for large and medium-sized gear speed reducer is different from the hydraulic oil pump only as far as possible to carry out the forward can run rules, just as it can be run and the rotation of the rotating this two kinds of different, so will its internal structure is different from the provisions of the hydraulic oil pump, both to its internal structure symmetry.

Many consumers who experience long-term application of rotating oil motor work experience can tell everyone with their own work experience, in the case of choosing low speed oil motor, choose goods with sufficient large reduction ratio category. And this kind of consumer usually has this kind of offer to everybody.

Everyone in the application of conveyor belt reducer, although as far as possible it can by virtue of its own effective role to make full use of, to promote all machinery and equipment can ensure the operation and full use of the role. But in terms of the specific application of machinery and equipment, in the case of opening and stopping the operation of machinery and equipment, is as far as possible the machine and equipment in the operation of the high efficiency level can ensure a lower level, so it will try to apply the motor here, can ensure a lower smooth reduction ratio.

In summary, the internal structure of the rotary excavator hydraulic motor is usually symmetrical, because everyone in the application of the commodity, as far as possible with the symmetry of the internal structure, to carry out the operation and rotation of the two different rotation.
