Problems solved by technology

[0003] 1. If straight teeth can be inserted, helical teeth or racks cannot be processed;
[0004] 2. It can not process straight teeth or racks if it can insert helical teeth, and it is a special machine that can only process one kind of fixed helix angle gear.
[0007] 1. The helical gear is processed by the method of internal spiral guide rail, which is mostly used by foreign imported machines to process helical gear. The characteristic of this method is that when the tool spindle is reciprocating in the axial direction, it is guided by a specific helical guide rail surface installed on the upper part of the machine tool to produce a The disadvantage of the helical motion with a fixed trajectory is that it has poor versatility. To process gears with different helix angles, the corresponding helical guide rail must be replaced, that is, the helix angle of the gear must be the same as that of the helical guide rail of the gear shaping machine. The precision requirement is very high, which brings many difficulties to the design and manufacture; it is understood that importing a pair of spiral guide bushes from abroad requires tens of thousands of dollars in foreign exchange and nearly a year, and can only be matched with corresponding imported guide bushes. It is very troublesome to replace the helical guide rail of the gear shaping machine. If it is disassembled frequently, the machining accuracy of the gear will be seriously affected. Therefore, it is almost unrealistic to process helical gears with different helix angles on the same helical gear shaping machine;
[0008] 2. Some people in China have proposed to process helical gears by using the differential principle. The main point of this method is: "When the main shaft of the gear shaping machine is moved up (or down) by one spiral lead of the gear shaping cutter, the gear shaping cutter will rotate just one ...

Abstract

The invention relates to the technical field of gear machining equipment manufacturing and mainly provides a new method, and a design theory, a working principle and a structural scheme of a multifunctional gear shaping machine which is designed by adopting the method, aiming at solving the defects of the existing oblique inner gear shaping and cutting method and the existing gear shaping machine. Specifically, the invention relates to a method for shaping and cutting oblique tooth gears, which is characterized in that an outer oblique tooth gear follow-up guide method is adopted, and circumferential feeding motion and additional rotation motion are obtained at the same time when a gear shaping cutter makes reciprocating linear motion to form a helical trajectory which is the same as a follow-up outer oblique tooth gear. The multifunctional gear shaping machine which is designed and manufactured by adopting the method is provided with an outer oblique tooth gear follow-up guide additional rotation mechanism and is equipped with a gear rack shaping special sliding table. When the outer oblique tooth gear follow-up guide additional rotation mechanism is connected, inner and outer oblique tooth gears can be machined; when the outer oblique tooth gear follow-up guide additional rotation mechanism is disconnected, inner and outer straight tooth gears can be machined; and when the gear rack shaping special sliding table is installed, straight tooth gear racks and oblique tooth gear racks can be machined.

Description

technical field [0001] The present invention relates to the technical field of gear processing equipment manufacturing, mainly aiming at the helical internal gear slotting processing method and gear shaping machine, the new method proposed and the design theory and working principle of the multifunctional gear shaping machine designed by applying the method and structural plans. Background technique [0002] As a kind of gear processing equipment, gear shaping machine has its unique advantages. For example, double gears and internal gears that cannot be processed on gear hobbing machines and milling machines can be easily processed and manufactured on gear shaping machines; however, now Some gear shaping machine tools have a single function, which is specifically reflected in: [0003] 1. If straight teeth can be inserted, helical teeth or racks cannot be processed; [0004] 2. It cannot process straight teeth or racks if it can insert helical teeth, and it is a special ...
