Specific embodiment
The utility model discloses a kind of coalcutter bumps tooth form chainless haulage running gears (abbreviation running gear), such as scheme
Shown in 1-6, including intermeshing traveling wheel 1 and pin row 2, the two sides tooth curve of both the traveling wheel and pin row is gradually
It bursts at the seams, the gear teeth flank of tooth of the traveling wheel is the curved surface of middle part evagination on facewidth direction, and the flank of tooth of the pin row is facewidth direction
What the curved surface of upper middle part indent, the traveling wheel and pin row were fitted into mutually bumps on the normal section of each position of engagement
State.The normal section extends along the normal direction of the flank of tooth of the position of engagement, because of referred to herein as normal section.Each position of engagement pair
Answer a normal section.By taking traveling wheel as an example, under the visual angle Fig. 3, the every bit on tooth curve has all corresponded to an engagement position
It sets, also just corresponds to a normal section.It was the normal section of one of position of engagement N shown in Fig. 5, i.e., by wherein one
Meshing point common normal and the section for being parallel to traveling wheel axis.
Further, the tooth of both the traveling wheel and pin row is all the tooth of symmetrical tooth form, the traveling wheel and pin row two
Contour line of two lateral tooth flanks of person on the normal section of each position of engagement is circular arc, and the radius of all circular arcs is equal
It is equal, it may be assumed that the arc radius of two flank profile lines of same tooth is equal on the same normal section, and same tooth difference engages position
The arc radius of flank profile line on the normal section set is equal, the above-mentioned arc radius of traveling wheel and the above-mentioned circular arc of pin row
It is also equal between radius.
After the flexible deformation of adjustment and the gear teeth after a period of time, the flank of tooth of traveling wheel gear tooth and the tooth of pin row tooth
It will gradually be rendered as the contact of curved shape line between the two of face, the sensitivity to processing and manufacturing error and deformation is reduced, not
The contact strength that same equal pitch running gear can be effectively improved in the case where increasing modulus, subtracts running gear contact stress obviously
Small, wearability and service life significantly improve.
Under the material and shape, the different situation of manufacture craft of both traveling wheel and pin row, the traveling wheel and pin row
Uniform strength design is preferably used in each position of engagement, with the comprehensive intensity and service life for improving the two.
After uniform strength design, the thin and thick of the tooth of both the traveling wheel and pin row is often inconsistent, the traveling wheel
Gear tooth it is usually unequal in the facewidth and reference circle transverse tooth thickness of its reference circle position.
