Problems solved by technology

As far as the current design methods are concerned, it is entirely possible to accurately design spherical involute bevel gears, but the bevel gears designed in this way can only be manufactured by plastic forming; while cutting processing methods are difficult to achieve accurate processing, because the spherical surface cannot be unfolded The cutting state of the current processing equipment is still linear, which can only satisfy the formation mechanism of the plane tooth curve.

Embodiment Construction

[0028] The present invention will be described in detail below with reference to specific embodiments.

[0029] The bevel gear tooth profile design method based on the conical surface involute includes the following steps:

[0030] In the first step, take the following set of parameters as an example, as the known parameters of the bevel gear to be designed: the big end module m=2.75mm, the number of teeth z=30, the pressure angle α=20°, the tooth tip height coefficient h a =1, the tooth root height coefficient h f =1.2, taper angle δ=56.3017°, tooth width B=15mm, calculated back taper angle δ b =90°−δ=33.6983°, and the taper distance R=(mz / 2) / sinδ=49.58108mm.

[0031] In the second step, take the back cone top of the bevel gear to be designed as the coordinate origin O, take the plane perpendicular to the axis of the bevel gear to be designed as the XY plane, and take the axis of the bevel gear to be designed as the Z axis, establish the OXYZ coordinate system, such as fig...

Abstract

The invention discloses a bevel gear tooth profile design method based on a circular conical surface involute. The bevel gear tooth profile design method based on the circular conical surface involute includes the steps of building a coordinate system, unfolding a bevel gear into a fan-shaped cylindrical gear, building a parameter equation for the fan-shaped cylindrical gear, building a parameter equation for the conical surface involute of the bevel gear, carrying out CAD drawing and the like. The bevel gear tooth profile design method based on the circular conical surface involute adopts an inverse unfolding method, builds the conical surface involute equation, is based on the inverse unfolding method, avoids the difficulty of design and manufacturing of a spherical surface involute profile, and also avoids the problem in the prior art that when a planar involute is used for replacing the conical surface involute to design the tooth profile, large errors are generated.

Description

technical field [0001] The invention belongs to the technical field of gear tooth profile design methods, and particularly relates to a bevel gear tooth profile design method based on conical surface involutes. Background technique [0002] Bevel gear transmission is used to transmit the motion and power between two intersecting shafts, and is mainly used in the intersecting shaft transmission of various mechanical equipment, such as automobiles, tractors, machine tools, reducers, etc. Among them, the curved bevel gear transmission is widely used in various high-speed and heavy-duty occasions due to its advantages of high coincidence, high bearing capacity and low noise; while the straight-tooth bevel gear transmission is generally used in light-load and low-speed occasions. [0003] The design accuracy of the bevel gear tooth profile affects the transmission performance of the bevel gear, and its design parameters are defined on the large end face. Theoretically, the tooth...
