Pin-Gear Drive is a special form of fixed axle gear transmission. The large wheel with cylindrical pin teeth is called pin wheel. It can be divided into outer gearing pin gear transmission (see Figure 3-7 ?), inner gearing pin gear transmission (see Figure 3-7 ?) and the rack gearing pin gear transmission (see Figure 3-7 ?). As the pin wheel is round pin shaped, it has simple structure, easy processing, low cost, easy overhaul compared to the general gear. Suitable for low-speed and heavy-duty mechanical transmission and for occasions with more dust, poor lubrication condition and so on.
At the heart of all our turntables is our own the Pin-Gear Drive system. It is a technically superior drive system, without the problems that are typically associated with friction drive systems.
Advantages of the Pin-Gear drive system:
1. Elimination of friction wheel slip.
2. Elimination of periodic friction wheel spring adjustments. Spring fade over time.
3. Ability to maintain precision rotation/angular accuracy and tracking. This is particularly important with antenna testing turntables and in other uses where backlash reduction or elimination is critical.
4. Fewer moving parts to maintain.
