Shaft Mounted Gearbox

Proven Solutions for Mining & Quarry

What is a Shaft Mounted Gearbox?

Shaft mounted gearboxes are fitted with electric motors, making them work faster than before. While manufacturing this shaft mounted gearbox, we are driven by high-quality raw materials and complicated technology. The shaft mounted speed reducer gearbox is facilitated with metallic double-lip oil seals. These help block out the dirt from the outside. All gear units are tested for gear cracks, noise, and leaks for a trouble-free operation. The gear units have an advanced tooth design to give a higher power-to-weight ratio for the same size gearbox.

We manufacture the shaft mounted gearbox per the set international quality standards, which offers you speed reduction by directly mounting it onto the drive shaft. These proposed shaft mounted gearboxes are straightforward to install and remove. We mainly provide the following three types of shaft mounted gearboxes.

SMR (TXT/SMRY) Series Shaft Mounted Gearbox Specification:

1. Shaft out hollow shaft The optional hollow shaft diameter of standard shaft is suitable for the size of SO standard shaft diameter.
2. High precision gear Computer designed helical gear shaft, high-strength alloy steel materials, carburizing and quenching, gear grinding process (part of the middle gear shaft shaving process), involute profile modification, in line with SO1328-1997 standard, each gear transmission efficiency as high as 98%, stable transmission, low noise.
3. High strength box The box is precision cast with high-strength cast iron, with excellent shock absorption and impact mitigation capability. The bearing aperture is precision machined, and the locating pin is accurately positioned to ensure the smooth engagement of the gear.
4. High strength alloy steel The input gear shaft is made of high-strength alloy steel, hardened, bearing gear, oil seal gear and input shaft excircle precision grinding, which can withstand the maximum radial load and torque. Long input keyway design, can withstand large impact, fully in line with SO standards.
5. Additional box support angle (excluding H and J) Support the torque arm bolts to prevent the bolts from being too tight and damaging the box. The installation position of the control standard torque arm is within the recommended range.
6. Backstop Optional accessories are used when the reducer cannot reverse (only used for 13:1 and 20:1 reducers, not recommended for 5:1 reducers).
7. Bearing and oil seal All bearings meet the SO standard, and the oil seal is even skeleton double lip oil seal.
8. Rubber oil cover Seal the middle gear shaft hole with a rubber sealing cap, with the standard hole size of SO.
9. Torque arm accessories Use the torque arm to install and adjust the spatial position of the reducer and the tightness of the belt.
