Embodiment 1
[0045] A modified double toroidal quadratic enveloping toroidal worm pair and a manufacturing method thereof. The center distance of the toroidal worm pair a=500mm, the number of heads of the toroidal worm Z 1 =2, right-handed, toroidal worm gear ratio i 12 = 50 / 2.
[0046] The manufacturing method of the present embodiment adopts following two steps to carry out:
[0047] The first step, manufacturing the toroidal worm
[0048] like figure 1 , 2 As shown in and 3, the grinding generation and the dynamic coordinate system σ are based on the double toroidal disc grinding wheel [2] installed on the tool seat 1 (O 1 i 1 , j 1 , k 1 ) of the toroidal worm blank [1], the tool holder and the moving coordinate system σ d (O d i d , j d , k d ) are fixedly connected, and the tool seat is relative to the static coordinate system σ of the tool seat od (O od i od , j od , k od ) performs a rotary motion, and the toroidal worm blank 1 is relative to the static coordinat...
Embodiment 2
[0067] A modified double-torus double-enveloping toroidal worm pair and its manufacturing method is composed of a toroidal worm and a matching worm gear. The basic parameters of the toroidal worm pair in this embodiment are the same as those in Embodiment 1, namely: the center distance a=500mm, the number of heads of the toroidal worm Z 1 =2, right-handed, toroidal worm gear ratio i 12 = 50 / 2.
[0068] According to Embodiment 1, the center distance modification is used alone, and the center distance modification amount Δa=0.15mm. However, due to the small value, it is difficult to adjust the worm processing machine tool to achieve the corresponding simple center distance modification. In order to adjust the machine tool conveniently and increase the flexibility of value modification parameters, this embodiment adopts comprehensive modification.
[0069] First take the fixed transmission ratio modification amount Δi=0.2, then the process transmission ratio for processing the...

Abstract
The invention relates to a modified double-toroid secondary enveloping toroid worm gear pair and a manufacturing method thereof. The technical scheme of the manufacturing method disclosed by the invention comprises the following steps of: grinding and spreading a toroid worm gear blank (1) by a double-toroid disc-shaped grinding wheel (2), wherein the process center distance is ad=a+delta a, and the process transmission ratio is i1d=i12+delta i; and adopting pure center distance profiling or adopting comprehensive profiling, determining profiling parameter ad and i1d by a trial method, calculating a worm gear engaging-out end reflecting line, and ensuring that the worm gear engaging-out end reflecting line can completely enter a first conjugate subarea of a worm wheel tooth surface. The cutting gear of a worm wheel is same as the relative standard transmission, only that a generative face of an applied toroid hob is consistent with a spiral surface of the modified worm gear. Accordingto the modified double-toroid secondary enveloping toroid worm gear pair disclosed by the invention, the worm wheel tooth surface does not exist a secondary contact area and can utilize the full length of a worm gear, a worm gear engaging-in end of the worm gear can keep the certain double-line contact length, and the manufacturing process is simpler and more flexible; and the modified double-toroid secondary enveloping toroid worm gear pair can also naturally inherit the advantages of standard double-toroid sedondary enveloping transmission.
Description
technical field [0001] The invention belongs to the technical field of secondary enveloping toroidal worm drive devices. In particular, it relates to a modified double-toroidal double-enveloping toroidal worm pair and a manufacturing method thereof. Background technique [0002] The patented technology of "a double-toroidal double-enveloping toroidal worm drive" (ZL 200920084461.6) discloses a standard toroidal worm drive without modification. surface, which can bring a series of excellent meshing characteristics, but part of the contact line intersects in the middle of the worm gear tooth surface, forming a so-called secondary contact area, which is a part of the worm gear tooth surface that is prone to failure, which restricts the full play of the transmission pair's bearing capacity and Further improve. [0003] The patented technology of "an angle-modified double-toroidal double-toroidal double-enveloping toroidal worm pair and its manufacturing method" (CN200910273347...
