Description
Technical Field
The invention belongs to the technical field of machining dies, and particularly relates to a design method of a hobbing die.
Background
At present, a large number of toothed stud parts are used in aviation and aerospace engines, and are required to have the most basic connecting function, anti-loosening function and anti-rotation function, a tooth-shaped part can smoothly enter a matched stop ring, and the tooth-shaped part can play the role of preventing rotation under the condition of not influencing assembly. Therefore, there is a need to develop a design method of a hobbing die.
Disclosure of Invention
In order to solve the above problems, it is an object of the present invention to provide a method for designing a hobbing die, which can design a complete hobbing die more efficiently without using three-dimensional software.
A design method of a hobbing die comprises the following steps:
(1) according to the reference circle Phid and the root circle Phid of the product1Addendum circle Φ d2Tooth tip width l1Root width of tooth2And determining parameters of a hobbing die of the hobbing die by the number of teeth n: root width L of gear hobbing die1Tooth top width L of gear hobbing die2Distance L between two adjacent tooth roots of gear hobbing die3The distance H between the tooth root and the tooth top of the hobbing die;
(2) drawing a two-dimensional plane diagram of the hobbing die according to parameters of the hobbing die, namely drawing the tooth root width L of the hobbing die1Tooth top width L of gear hobbing die2Distance L between two adjacent tooth roots of gear hobbing die3The distance H between the tooth root and the tooth top of the hobbing die is connected with the end points of all sizes, so that beta can be obtained, wherein the beta is an included angle between two adjacent teeth of the hobbing die, the alpha is an included angle between two adjacent teeth of a product to be processed, and the beta is not equal to the alpha;
(3) and processing the hobbing die according to the two-dimensional plan of the hobbing die.
Root width L of the gear hobbing die1Tooth tip width l1Tooth top width L of gear hobbing die2Root width = tooth root width =2And the distance H between the tooth root and the tooth top of the gear hobbing die = the addendum circle Phid2Root circle Φ d1Distance L between two adjacent tooth roots of gear hobbing die3= reference circle Φ d/number of teeth n.
Compared with the prior art, the design method of the hobbing die has the beneficial effects that: the design method is simple, convenient to operate, easy to design and process, good in interchangeability and strong in universality, and the production efficiency is effectively improved.

Detailed Description
The principles and features of this invention are described below in conjunction with examples, which are set forth to illustrate, but are not to be construed to limit the scope of the invention.
As shown in fig. 1 to 3, a method for designing a hobbing die includes the steps of:
(1) according to the reference circle Phid and the root circle Phid of the product1Addendum circle Φ d2Tooth tip width l1Root width of tooth2And determining parameters of a hobbing die of the hobbing die by the number of teeth n: root width L of gear hobbing die1Tooth top width L of gear hobbing die2Distance L between two adjacent tooth roots of gear hobbing die3The distance H between the tooth root and the tooth top of the hobbing die;
(2) drawing a two-dimensional plane diagram of the hobbing die according to parameters of the hobbing die, namely drawing the tooth root width L of the hobbing die1Tooth top width L of gear hobbing die2Distance L between two adjacent tooth roots of gear hobbing die3The distance H between the tooth root and the tooth top of the hobbing die is connected with the end points of all sizes, so that beta can be obtained, wherein the beta is an included angle between two adjacent teeth of the hobbing die, the alpha is an included angle between two adjacent teeth of a product to be processed, and the beta is not equal to the alpha;
(3) and processing the hobbing die according to the two-dimensional plan of the hobbing die.
Root width L of the gear hobbing die1Tooth tip width l1Tooth top width L of gear hobbing die2Root width = tooth root width =2And the distance H between the tooth root and the tooth top of the gear hobbing die = the addendum circle Phid2-toothRoot circle Φ d1Distance L between two adjacent tooth roots of gear hobbing die3= reference circle Φ d/number of teeth n.
The scope of the present invention is not limited to the technical solutions disclosed in the embodiments, and any modifications, equivalent substitutions, improvements, etc. made to the above embodiments according to the technical spirit of the present invention fall within the scope of the present invention.
