If you are thinking of purchasing sector gears for smooth operations, you need to make the right choice. To do so, you can go through our blog:
Sector Gears, also known as partial gears, are used in steering mechanisms, valve control systems, and mechanical linkages. They provide high torque, compact, and controlled motion.
You will find the worm and sector steering gear in the steering wheel mechanism, where the worm gear and sector gear are used to rotate the steering wheel in the angular direction of the vehicle wheel.
The following table talks about the key differences between worm and sector gears.
| Parameter | Worm Gear | Sector Gear |
|---|---|---|
| Definition | A gear system consisting of a worm (screw-like shaft) that meshes with a worm wheel to transmit motion. | A portion (segment) of a circular gear with teeth cut on only part of its circumference. |
| Structure | Includes a threaded worm and a matching gear wheel. | A partial gear shaped like a sector of a circle. |
| Motion Type | Provides continuous rotary motion between non-parallel shafts (usually at 90°). | Converts rotary motion into limited angular or back-and-forth movement. |
| Power Transmission | High torque transmission with speed reduction capability. | Moderate power transmission for controlled movement. |
| Self-Locking Feature | Often self-locking (prevents reverse motion). | Not self-locking; can rotate freely. |
| Contact Type | Sliding contact between worm and wheel teeth. | Rolling contact between gear teeth. |
| Efficiency | Lower efficiency due to friction and heat generation. | Higher efficiency with less friction loss. |
| Load Capacity | Suitable for heavy loads and high-torque applications. | Used for lighter loads and intermittent motion. |
| Applications | Conveyors, elevators, steering systems, lifting equipment, and speed reducers. | Steering mechanisms, valve control systems, clocks, and mechanical linkages. |
| Cost & Maintenance | Higher maintenance due to wear and lubrication needs. | Lower maintenance and simpler design. |
Here are some of the advantages: They are
In a sector gear mechanism, you will find all the above-mentioned points, which state the smooth operation and control of motion.
The following table talks about the technical specifications of sector gears.
| Parameter | Description | Details |
|---|---|---|
| Gear Type | Partial gear with teeth on a segment of a circular disc | Spur sector gear, helical sector gear |
| Material | Material used for strength and durability | Steel, stainless steel, cast iron, brass, bronze, engineering plastics |
| Module (Metric System) | The size of gear teeth determines pitch and dimensions | 0.5 – 20 modules (application dependent) |
| Diametral Pitch (Imperial) | Number of teeth per inch of pitch diameter | 2 – 24 DP |
| Pressure Angle | Angle between gear tooth force and tangent line | 14.5°, 20° (most common), 25° |
| Number of Teeth | Teeth present on the gear segment | As per the design requirement |
| Pitch Diameter | Diameter of the pitch circle of the full gear | Custom-designed |
| Face Width | Width of the gear tooth surface | 5 mm – 200 mm (varies by load capacity) |
| Tooth Profile | Shape of gear teeth for smooth engagement | Involute tooth profile (standard) |
| Sector Angle | Angular portion of the gear | Typically 30° – 180° |
| Mounting Type | Method used to attach the gear to the shaft or mechanism | Keyway, hub mounting, bore mounting |
| Surface Finish | Tooth finishing for smooth operation | Ground, machined, hardened |
| Heat Treatment | Process to increase hardness and wear resistance | Case hardening, carburizing, induction hardening |
| Load Capacity | Ability to withstand force or torque | Depends on material, module, and design |
| Operating Speed | Speed range suitable for operation | Low to moderate speeds |
| Accuracy Grade | Precision level of gear teeth | Standard industrial or precision grade |
| Lubrication Requirement | Lubrication for reducing wear and friction | Grease or oil lubrication |
