Embodiment Construction

[0031] Aiming at the deficiencies of the prior art, the present invention overcomes the technical barrier of the ideal form of meshing, creates the system theory of "principle and manufacture of arc helical cylindrical gears", and demonstrates the basis of various parameters. The ratio relationship between R, L and m in the figure People call it "Wanyan Xueming Standard", which regulated the cutting tool standard, matched the process standard, invented "arc spiral cylindrical gear and arc rack" and various gear making machine tools, and expanded the scope of application.

[0032] The main structure of the arc helical cylindrical gear of the present invention is as follows: figure 1 Shown: It consists of convex tooth surface 1, concave tooth surface 2, dedendum 3, and tooth top 4. The midpoint section contour lines 13 and 14 of the tooth length L are the involute tooth profile of the spur gear, and the section away from the midpoint becomes the involute tooth profile of the hel...

Abstract

The invention discloses an arc spiral cylindrical gear. Contour lines (13 and 14) of a mean section of tooth length of a gear tooth on a convex tooth surface (1) and a concave tooth surface (2) are involute profiles of a spur gear, the section apart from the center point is changed into an involute profile of a helical gear, the involute profiles of the spur gear respectively screw to contour involutes (5, 6, 7 and 8) of two end faces of the helical gear from the center point to two ends along a convex tooth top camber line (9) and a convex tooth bottom camber line (10) on the convex tooth surface (1) and a concave tooth bottom camber line (11) and a concave tooth top camber line (12) on the concave tooth surface (2) so as to form a two-way arc screw gear tooth comprising a two-way screw tooth portion with one end provided with a right screw arc helical gear and the other end provided with a left screw arc helical gear. Arc screw meshing tracks of pitch circles and the like of the gear and the rack are accurate, and a concave tooth top arc is equal to a convex tooth bottom arc and is larger than a convex tooth top arc and a concave tooth bottom arc, thereby forming a 100 percent of contact surface and creating a new meshing principle.

Description

technical field [0001] The invention relates to a transmission gear, in particular to an arc helical tooth line cylindrical gear and an arc rack derived from the introduction of extended theory. On the same principle, the two original parts mesh with each other to convert their motion modes. Background technique [0002] Gear transmission is the most widely used form of transmission. At present, there are three forms of cylindrical gear "tooth line": spur gear (spur gear), helical gear (helical gear), and herringbone gear (double helical gear). The fourth form is The little-known "circular tooth line cylindrical gear" is the research subject of "curved tooth line meshing form" published by the United States in 1975. The samples exhibited at the International New Technology Exhibition in 1986 had an involute tooth shape in the central section of the tooth width, and it became an approximate value when it was away from the center. The contact surface of the "tooth line" did n...
