Sumitomo CHHJ-4155Y-87 Inline Gear Box
The Sumitomo CHHJ-4155Y-87 87:1 Ratio Inline Gear Box is an industrial speed reducer for controlled motion and torque multiplication. It is identified by the CHHJ-4155Y-87 model reference. The gearbox has a ratio of 87 to 1. It provides an output speed of 20 RPM and a torque rating of 9550. The unit is rated at 3.29 HP. It is designed for inline mounting and is used in heavy duty machinery.
Inline Gear Box Design
An inline gear box places the input and output shafts on the same axis. This arrangement saves space and simplifies machine layout. The CHHJ-4155Y-87 uses hardened gears and heavy duty bearings. The housing protects internal parts from dust, moisture and impact. Seals retain lubricant and keep contaminants out. The output shaft and mounting flange are machined for accurate fit.
Ratio and Output Performance
The 87 to 1 ratio provides strong speed reduction and torque multiplication. The output speed is 20 RPM. The torque rating is 9550. The unit is rated at 3.29 HP. Users should compare the required torque, speed and duty cycle with these ratings before installation. Overloading can cause gear wear, overheating or premature failure.
Applications
Typical applications include belt conveyors, screw conveyors, bucket elevators, mixers, agitators, feeders, crushers and production lines. The gearbox is suitable for industries such as mining, cement, food processing, wastewater treatment, chemical processing and general manufacturing.
Installation Notes
Installation should follow the equipment manual. The mounting base should be stable and flat. The motor shaft and reducer input must be aligned carefully. Couplings must be aligned to avoid extra load on bearings and gears. Bolts should be tightened evenly and to the correct torque. After installation, check oil level and rotation direction before connecting the load.
Lubrication and Maintenance
Correct lubrication is essential for gearbox life. Oil type and level depend on the model, mounting position and operating conditions. Users should check for leaks and maintain the oil level. Oil should be changed according to schedule or analysis. Bearings and seals should be inspected during major service. Noise, vibration and temperature should be monitored.
Conclusion
The Sumitomo CHHJ-4155Y-87 87:1 Ratio Inline Gear Box is a robust reducer for heavy duty motion control. It provides 20 RPM output, 9550 torque and 3.29 HP capability. Correct selection, installation and maintenance help ensure long service life.
