Internal Gears
Internal Gears have teeth pointing towards the center with addendum and dedendum taking reverse positions. These gears are also designed to make available compact in addition to parallel shaft transmission drive with a choice of better speed diminution as preferred by the operators. These gears, when used with stock, encourages the elimination of freeloader gear where two parallel shafts need to be swiveled in the same direction.
With cylindrical exterior, these gears come with teeth that are parallel to axis cut from the inside rim and are used to carry the load efficiently as well as make sure that there is an even distribution. Making use of the rotary motion between parallel shafts rotating in the same direction, the fine quality non-binding tooth structure provides for smooth as well as soundless operations. Additionally, these gears also provide for low sliding as well as high-stress loading operations.
Features:
- Allows reduced sliding action.
- Corresponding working surfaces of internal gear teeth and pinion of the same length that allows for relative less slippage of teeth.
- Less tooth wear due to less friction between gear teeth.
- There is a difference between the placement of the gear teeth to avoid the possibility of interference
- Requires a reduced amount of safeguarding and offers steadfast operation.
- Designed to keep away from issues associated with collision with spokes, as well as wheel-collapse.
- Can be operated with gear in a fixed position as well as with pinion rotating along the pitch line.
- Allows changes in gear ratios in case the rear wheel is not in proper rotation.
- Brass made internal gears are cost-effective.
Specifications:
- Accessible in different metal finishes together with stainless steel, bronze, aluminum, cast iron and others.
- Can also be manufactured to personalized specifications as per customer’s requirements.
- While choosing a mating spur gear, forever remember that the difference in the number of teeth between the internal gear and pinion should not be less than 15 (14 1/2° PA) or 12 (20° PA).
Applications
- Planetary Gear Drives
- Segment Gears
- Used with stock spur pinion
- Positioning equipment
- Roller tools
- Indexing equipment
- Timing systems
- Light duty applications
Also used in industry sectors like Sponge Iron Plants, Cement Plants, Sugar Mills, Fertilizer Plants.
Internal gear hubs provide a reliable gear shifting option to cyclists. They are better than derailer systems and require less maintenance.
