1.Bevel Helical Gear box Specifications

HB series gearbox reducer Helical Gearbox

Bevel Helical Gear box Input mode: Motor connection flange, shaft input Gear Speed Reducer

HB gearbox reducer adopts the general design project, which can change them into special-for-industries gearboxes according to different requirements of customers. Bevel Helical Gear box apply sound-absorption box structure. The larger surface area and big fan, column gear and helical gearwheels all introduce the advanced gear-grinding craft which can lower the noise, improve the running reliability and efficiency of speed reducers. Meanwhile, HB gearbox reducer we manufacture is in accord with the quality standards of both China and abroad.

3.Details of HB gearbox reducer:

3.1 Bevel Helical Gear box: can perform vertical crossing axis, vertical functions, with its components species decreasing, and specs increasing.

3.2 Gearbox reducer Input mode: Motor connection flange, shaft input.

3.3 Bevel Helical Gear box Output mode: solid shaft with flat keys, hollow shaft with flat keys, bulge-tight discal coupling hollow shaft, spline coupling hollow shaft, spline coupling solid shaft and flange coupling solid shaft.

3.4 Gearbox reducer Installation type: horizontal, vertical, base-swing type, force arm-twisting types

3.5 B series Bevel Helical Gear box has specs ranging of 3~26, deceleration transmission grades range of 1~4, speed ratio: 1.25~450, if combined with our R K S series it will produce a higher speed ratio

Why Choose us:

1) All torque arms/fulcrums are plated to eliminate them being rusted in use.

2) The shaft mounts have labyrinth sealing on the conveyor end and input shaft end so that the oil seal is safe from contamination.

3) The front end of the shaft mount has a hub cover to protect the front oil seal as well as moving part of the gearbox.

4) Input shaft front bearing is a roller bearing as it takes in more radial load from the belt pressure.

5) Breather plugs are extended so that the dust does not clog the breather hole.

6) All oil seals imported from Taiwan.

7) Our gear units now have higher load capacity as the gears have been redesigned. 8) All gears are case carburised to a casedepth and ground inhouse.

9) All gear units are machined on a CNC machining center so are very accurate in alignment.

10) Finish of all gear units are far superior to any other brand being sold out.

11) The shaft mounts are available with keyed hollow shafts or hollow taper bores with taper clamps.
