Classification by cam shape
1. Arc cam indexer: The arc conjugate cam on the input shaft meshes vertically with the indexing wheel on the output shaft without gap. The curved segment of the cam profile drives the indexing wheel to rotate, and the straight segment makes the indexing wheel stationary and self-locked in position, which can convert continuous input motion into intermittent output motion. It is often used in high-precision, high-load automation equipment.
2. Planar cam indexer: The plane conjugate cam on the input shaft meshes parallelly with the indexing wheel on the output shaft without gap. Similarly, the indexing wheel is rotated and stationary through the curved and straight segments of the cam profile surface. It is suitable for some occasions with high precision requirements but relatively small loads.
3. Cylindrical (barrel) cam indexer: It belongs to a heavy-load special platform cam indexer, which is often used as a frame-type cam indexing mechanism for electric light source equipment, and can achieve precise indexing motion under heavy load conditions.
Classification by output shaft structure
1. Spindle type indexer (DS): The output shaft is a spindle, which is suitable for intermittent transmission conveyor belts, gear meshing and other mechanism power sources. It can be installed with gears, couplings or coupling discs, and has the characteristics of simple structure and stable transmission.
2. Flange type indexer (DF): The output shaft has a flange shape, which can withstand large vertical radial or axial pressure. The positioning and fixing installation surface is large, making the connector more solid and stable. It is widely used in rotary disc drive occasions with large loads.
3. Ultra-thin platform desktop indexer (DA): The size design characteristics are similar to the platform desktop type. It is suitable for conditions where the load is large but the volume is limited. It can provide strong load capacity in a limited space and meet some occasions that require high compactness of the equipment.
4. Platform desktop cam indexer (DT): It can withstand large loads and vertical radial pressures. The output shaft end has a raised fixed disc surface and a large-diameter hollow shaft. The power source's electricity, oil, and gas pipelines can be placed in the hollow hole. It is often used in various types of machinery with heavy loads and direct-connected automation equipment.
