Problems solved by technology

The main defect of this mechanical spiral groove type additional rotation is: frequent friction between the cutter shaft and the spiral groove, not only the helical guide rail is easy to wear, but also increases power consumption; when changing the helical angle of the processed helical gear, the spiral groove guide rail must be replaced accordingly Adapt to the needs of processing helical gears with different helix angles

Embodiment 1

[0018] like figure 1 As shown, the rack and differential gear shaping machine transmission device includes a crank slider mechanism, a rack assembly 5, an intermediate transmission device, a differential transmission device, a worm and worm gear transmission mechanism, a cutter shaft, and a cutter shaft transmission mechanism;

[0019] The slider crank mechanism comprises a crank disc 1, a connecting rod 2, a slide block 4, and a crank shaft 33. The crank shaft 33 is supported by bearings on the gear shaping machine tool body 3 (the crank shaft 33 can rotate), and the crank disc 1 is fixed. Installed on the crank shaft 33, the crank disc 1 and the crank shaft 33 are perpendicular to each other, and one end of the crank shaft 33 is connected with the output shaft of the main motor of the gear shaping machine tool by a coupling or a transmission mechanism (the crank disc is controlled by the main motor of the gear shaping machine tool. Driven by a motor, the main motor of the ge...

Embodiment 2

[0030] It is basically the same as Embodiment 1, except that the cutter shaft transmission mechanism includes a sliding sleeve 11 and a cutter shaft driving wheel 10, the sliding sleeve 11 is fixedly installed on the cutter shaft 12, and the cutter shaft driving wheel 10 is sleeved on the sliding sleeve 11, Sliding sleeve 11 is provided with key or protruding slide block along the axial direction of cutter shaft 12, is provided with chute in the hole on the cutter shaft transmission wheel 10, and key or protruding slide block is positioned at chute (cutter shaft transmission Both the wheel 10 and the sliding sleeve 11 can slide linearly, and simultaneously the cutter shaft drive wheel 10 can drive the sliding sleeve 11 and the cutter shaft 12 to rotate together).

Abstract

The invention relates to a gear shaper transmission device. A rack differential gear shaper transmission device comprises a crank sliding mechanism, a worm and worm gear transmission mechanism and a cutter shaft, wherein the upper end of the cutter shaft is connected with a sliding block in the crank sliding mechanism by a kinematic pair, and the lower end of the cutter shaft is fixedly provided with a gear shaper cutter. The device is characterized in that: a rack assembly is fixedly arranged on the sliding block of the crank sliding mechanism, and a rack of the rack assembly is engaged witha gear of a middle transmission device; a first bevel gear of the middle transmission device is fixedly arranged on a differential main shaft of a differential transmission device; and a differentialinput wheel of the differential transmission device is connected with a worm gear driving wheel in the worm and worm gear transmission mechanism by a second driving belt or a second driving chain, a dual output driving wheel of the differential transmission device is connected with a cuter shaft driving wheel of a cutter shaft transmission mechanism, and the cutter shaft transmission mechanism isarranged on the cutter shaft. The device not only can overcome the defect of easy abrasion of a spiral guide rail, but also can conveniently meet the requirement of processing bevel wheels of different spiral angles.

Description

technical field [0001] The invention relates to a transmission device of a gear shaping machine, in particular to a transmission device of a gear shaping machine used for processing helical gears (or called helical gears). Background technique [0002] Helical gears (or helical gears) have the characteristics of smooth transmission, low vibration and noise during the meshing process, and are widely used in high-speed, heavy-duty, and low-noise transmission. Gear shaping is an irreplaceable gear machining method with many advantages. [0003] Gear shaping is a common method for machining helical gears. In addition to the normal motion between the tool shaft and the workpiece, in order to realize the processing of helical gears, the gear shaping tool shaft must have additional rotational motion, and the rotational motion Steering is frequently changed forward and reverse. [0004] At present, the additional rotation of the cutter shaft of the gear shaping machine generally a...
