High Efficiency Cast Iron Bevel Helical Gear Units Transmission Gearbox For Crusher

Design:
PV series gear unit is a completely new design. Advantages are:
1) Highly standard modular designed, more sizes with a reduced variety of parts.
2) Higher operational reliability combined with increased power capacity.

Mounting position:
The gear units can be supplied for either horizontal or vertical installation.
Other arrangements are also possible on request.

Long service life:
Under the condition of accurately selecting type size and the normal maintenance and use, main components(expect those easily-disabled parts) can last as long as up to more than 50,000 hours.

Low noise:
All key components are finished by precisely machining: grinding the gears; designing noise absorbing housings; accurate assembly, and finally tested, and therefore, fairly low noise is reached.

Thermal conduction:
Industrial gear units have a favorable Thermal conduction, because:
1) The gear units have a high efficiency.
2) Through enlarged housing surface areas.
3) Because large fans incorporating a new type of air conduction fan cowl are being used.

Type and Size:
H.B. (P.V.) series gear units include sizes 3-26, number of stages is 1-4, and ratio is 1.25-450.
Combining with CR, S and K series, ratio will be higher.

Noise Behaviour:

New concepts were applied to clearly improve the noise emission of the gear units  Designing noise-absorbing case Achieving exceptionally large contact ratios  All the gears have been grinded .

 Thermal conduction:

Gear units not only have a high efficiency but also have a favorable thermal conduction 

Through enlarged housing surface areas; As large fans incorporating a new type of air conduction fan cowl are being used  Selection of gear unit is based on a lower maximum oil temper ature .By that ,the operational  reliability will be increased and the cost of maintenance reduced due to longer oil change intervals 

Storing 

Gear units have been designed according to a new unit construction principle ,which reduce the variety 

of components
