H Series Parallel Shaft Helical Gear Unit Parallel Shaft Industrial Gear Reducer
Description:
H Series industrial helical parallel shaft gear units are high-quality gearboxes for heavy-duty industrial applications. All mechanical parts are analyzed with state-of-the-art software to guarantee their reliability. We also offers tailored solutions for specific applications.
High efficiency H series helical parallel shaft industrial gearboxes have been introduced to meet the requirements of today's demanding applications in the medium and heavy-duty sector of the power transmission market. The purpose of using the parallel shaft gearbox is to reduce the speed and increase the torque. It is suitable for high-speed axle speed not more than 1500 rpm, gear drive circumferential speed not more than 20 m/s, working environment temperature is -40ºC~+45ºC. The gearboxes are compact, totally enclosed and are designed for direct mounting to ensure highest precision positive drive and permanent alignment minimizing space requirement and layout problems. H series parallel shaft helical gearbox offers unlimited installation flexibility.
CHARACTERISTICS:
