Product Description
Customizable cylindrical worm hob, enveloping worm hob, double-lead worm hob, multi-head worm hob. Depending on actual needs, inlaid, integral, straight groove, spiral groove, surface coating and other processes can be selected.
Structural Features
- Hole Design Hole-type worm hobs have a central hole, which is mounted on a hobbing machine via a mandrel to achieve tool positioning and rotary drive. This mounting method ensures the stability and accuracy of the hob during processing.
- Axis Table as Correction Baseline The diameter of the axis tables at both ends serves as the process correction baseline. The axis table length is typically 10mm-15mm, the equal diameter tolerance is 0.003mm, the surface roughness Ra is 0.8μm, and the circular runout of the common axis is 0.005mm. This provides a calibration basis for the correction of the hob axis line parallelism to the worktable surface, the measurement of the installation center height, and the inspection of the radial circular runout after installation.
Working Principle
During operation, the hob acts like a helical gear with a large helix angle. It meshes spatially with the worm blank as a pair of helical gears, rotating at a fixed speed ratio. The tooth profile of the worm is enveloped by the successively cut tooth shapes of adjacent teeth.
Applicable Scenarios
- Large Diameter, Large Module Worm Wheel Machining Often used for machining large diameter and large module worm wheels. It is widely used in worm wheel machining in fields such as mining machinery, heavy machinery, and shipbuilding. Worm wheels in these fields are usually large in size, and hole-type worm hobs can better meet the processing requirements.
- High-Precision Worm Wheel Machining For worm wheel machining with high precision requirements, hole-type worm hobs can ensure machining accuracy through precise installation and adjustment, meeting the needs of aerospace, precision instruments, and other fields.
