shaft mount reducer

A gear acceleration reducer is a representative exemplory case of swiftness changers, and presently used devices can be categorized by the type of gears, shaft positions and arrangement of gears into (1) equipment reducer with parallel axes, (2) equipment reducer with orthogonal axes, (3) equipment reducer with perpendicular nonintersecting axes, and (4) equipment reducer with coaxial axes.

Types and mechanisms of equipment planetary gearbox reducers with parallel axes
The apparatus reducers with parallel axes use spur gears, helical gears, or herringbone gears. Their input and output shafts are parallel. As for decrease ratios, 1/1 – 1/7 for one-stage shafts, 1/10 – 1/30 for two-stage shafts, and 1/5 – 1/200 for more than three-stage shafts are commercially available. The overall characteristics of gear reducers with parallel axes are as follows :

For high precision gears, the transmitting efficiency is very high. (98 to 95% for one-stage equipment reducer)
When properly lubricated, it can be used for a long period.
Can be produced relatively cheaply since standardized gears are used.
Gear reducers with spur gears are used for increasing acceleration.
The sizes of gear reducers with spur gears are is normally large. In comparison to worm gear reducers with the same swiftness ratio, their outer shapes are large, and the amount of parts increases leading to constructional disadvantages. As a result, it can be used for machines with high rotation on the strain side, or which need higher output rotation compared to the primary movers (for increasing speed). The gear types are proven in Table 2.1.

The gear reducers with parallel axes usually use helical gears. They are used in steel facilities, ships, cranes, elevators, and conveyors. As for automation machines, these equipment reducers are also known for geared motors which are equipment reducers with directly linked motors.
