Problems solved by technology

Depend on figure 1 It can be seen that there are more than 10 cutting edges on each side of the tooth surface of a standard shaving knife, but only one point on the contact line of each cutting edge participates in cutting processing, and the rest does not work, that is, each cutting edge has at most about The contact length of more than 1mm plays a cutting role, and during the whole reciprocating feed cutting process, only one cutting point of each blade is repeatedly involved in cutting, so the wear of this place is faster, which naturally seriously affects the durability of the tool

Embodiment Construction

[0071] The design calculation and experimental analysis of the tool with a modulus of 3.75mm can make each blade fully capable of continuously participating in cutting from the root of the tooth to the top of the tooth. This improvement alone increases the life of the tool by at least 10 times. The larger the modulus, the longer the life.

[0072] We have developed a computer-aided design program (PICM), which can fit the projected curve of the tooth end surface closely related to the contact line of the tooth surface into an approximate involute end section tooth profile with full cutting function, namely knife-edge curves (such as figure 1 , figure 2 and image 3 , Figure 4 shown), and the error is very small. The approximate involute tooth shape has the corresponding base circle diameter and pressure angle correction value. According to any parameter, the full-cut end section tooth shape (that is, the blade shape) can be ground on the gear grinding machine, that is, th...

Abstract

The present invention relates to gear manufacturing technology, and is especially completely cutting gear shaped gear shaving cutter with involute end section edge for finishing of gear before quenching, completely cutting gear shaped honing wheel for machining hard gear surface after quenching and their usage. The present invention includes skewed-tooth gear shaving cutter and skewed-tooth honing wheel, and features that each edge can cut from the dedendum to addendum continuously and that each tooth shape curve of the skewed-tooth gear shaving cutter and the skewed-tooth honing wheel is fitted into approaching involute. The present invention is realized with the special design program PICM.

Description

1. Technical field [0001] The invention discloses a full-cutting helical gear shaving cutter, a helical gear honing wheel and a design method thereof, which belong to the technical field of gear manufacturing, and specifically relate to a full-cutting full-cutting tool with an end section involute tooth-shaped edge used for finishing the soft tooth surface of a gear before quenching A type gear-shaped gear shaving cutter, a full-cut gear-shaped honing wheel for finishing hardened tooth surfaces after gear quenching, and a design method thereof. 2. Background technology [0002] The gear-shaped shaving cutter has been invented and applied by the United States in 1932. It is characterized by cutting more than ten holes with a width of about 1mm and a depth of about 0.8mm on the tooth surface of the "gear-shaped high-speed steel shaving cutter" along the tooth height direction. Chip groove, the groove intersects with the involute helical tooth surface to form an involute tooth ...
