Abstract

The invention discloses a sector static pressure rotary work table and a gear cutting machine. A big friction wheel (5) of the sector static pressure rotary work table is fixed on the upper end face of a sliding table (1), a pressing plate (2) is arranged between the sliding table (1) and the big friction wheel (5), the pressing plate (2) is fixed on the lower end face of a workpiece box body (4), an upper friction pair surface is formed between the upper end face of the pressing plate (2) and the big friction wheel (5), a lower friction pair surface is formed between the lower end face of the pressing plate (2) and the sliding table (1), an upper oil cavity (2-1) and a lower oil cavity (2-2) are arranged on the upper friction pair surface and the lower friction pair surface respectively, and the area of the lower oil cavity (2-2) is larger than that of the upper oil cavity (2-1). The big friction wheel of the rotary work table is free of abrasion during operation, stable in movement, good in rigidity, high in precision, simple and reasonable in structure, easy to machine and manufacture and convenient during oil return and can effectively guarantee the whole machine cutting precision of the gear cutting machine.

Description

technical field [0001] The invention relates to the technical field of gear processing equipment, in particular to a fan-shaped static pressure rotary table of a gear processing machine tool. The invention also relates to a gear machining machine tool provided with such a table. Background technique [0002] The rotary table of the traditional gear processing machine tool uses tapered roller bearings in the center of rotation to realize the axial and radial positioning and rotary support of the mandrel. The tail of the rotary table generally uses 3-4 unloading rollers to realize rotary telemotion and rotary support. [0003] Please refer to figure 1 , figure 1 It is a schematic diagram of the rotary structure of the rotary table of the traditional gear processing machine tool. [0004] As shown in the figure, it generally includes a sliding table 1', a pressing block 2', a rotary table 3', a workpiece box 4', a large friction wheel 5', a cylindrical roller bearing 6', an ...
