feed and dressing movements are controlled by means of two independent driving systems.Size-metric grinding is adopted.Feed movement can be caried out both manually and hydraulically.

※ Feed and dressing movements are controlled by means of two independent driving systems.Size-metric grinding is adopted.Feed movement can be caried out both manually and hydraulically.
※ Because the machine is quipped with jumping mechanism,it is unnecessary to reset the tool after returning grinding wheelfor measurement or dressing.
※ The machine is equipped with a hydraulic switch valve to ensure safety during loading and unloading workpieces
※ A grinding spindle with 18,000 r/min.is optional for grinding bore diameter ranging from 20 to 50mm.
※ An endface grinding device is provided on the top of the workhead.There is a hydraulic interlock system between the swivel of the endface grinding device and the longitudinal movement of the worktable.

A worm gear drive is a mechanical transmission device composed of a worm wheel and a worm. Its core function is to realize the movement and power transmission between two spatially intersecting shafts. This transmission method operates through the meshing of the worm (a rod-shaped component with threads) and the worm wheel (a gear with matching teeth), which significantly reduces the rotational speed or generates a large torque. It is widely used in industrial equipment, transportation vehicles and other fields.

Historical Origin and Development

The history of the worm gear drive can be traced back to ancient Greece. Its invention may be attributed to Archytas, Apollonius or Archimedes, among whom Archimedes' contribution is the most recognized. By the 13th - 14th centuries, the Delhi Sultanate on the Indian subcontinent had applied the worm gear drive to cotton gins, marking the beginning of its early industrial application.

Structure and Working Principle

The typical structure of a worm gear drive includes an input shaft (the worm) and an output shaft (the worm wheel) that are perpendicular to each other. When the worm rotates, its threads mesh with the teeth of the worm wheel, pushing the worm wheel to rotate at a specific angle. If a single-threaded worm is used, for every 360-degree rotation of the worm, the worm wheel only advances one tooth, thus achieving a reduction ratio of up to 20:1. Compared with traditional spur gear drives, the worm gear drive can achieve the same reduction effect in a more compact space (for example, traditional gears require a 240-tooth pinion to match a 20-tooth gear).
