Abstract
The utility model discloses a crawler driving wheel which comprises a wheel main body and wheel teeth, wherein, the wheel teeth comprises a circular-arc-shaped tooth top part, a tooth root part, and an involute-shaped meshing part which is positioned between the tooth top part and the tooth root part. Because the meshing part of the driving wheel of the utility model is of an involute shape, when neutral position formed by two crawler boards is meshed, impact and relative friction which are generated when the wheel teeth of a linear type driving wheel is meshed in and engaged out is reduced, and the meshing is smooth and continuous in the whole running process.
Description
Technical field
The utility model relates to a kind of drive wheel, particularly a kind of track sprocket, and it can be used for various track-type machineries, is particularly useful for large-scale crawler crane.
Background technology
Existing crawler type walking mechanism, the gear teeth tooth top and the tooth root of its used drive wheel partly adopt arc transition, and mate adopts linear, and like this under heavily loaded situation, this drive wheel all exists with caterpillar block and meshes jiggly problem.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of and caterpillar block ingear pulsation-free track sprocket more, the technical scheme that it adopts is: a kind of track sprocket, it comprises the wheel body and the gear teeth, wherein the gear teeth comprise the tooth top partial sum tooth root part of circular arc, and the mate that is involute arc between tooth top partial sum tooth root part.
The beneficial effects of the utility model are:
Because tooth mesh partly is an involute shape in the utility model, so when the engaging-in two formed neutral gears of caterpillar block of the drive wheel gear teeth, be similar to the gear motion of rack-and-gear, reduced the impact engaging-in, that produced when nibbling out of the linear pattern drive wheel gear teeth, relatively friction, make in the whole walking process engagement steadily, link up.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the structure enlarged diagram of the gear teeth among Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1 and Figure 2, a kind of track sprocket of the utility model comprises the wheel body 1 and the gear teeth 2; Wherein the gear teeth 2, comprise the tooth top part 201 and the tooth root part 203 of circular arc, and the mate that is involute shape 202 between tooth top part 201 and tooth root part 203.
In the actual techniques design, the needs according to complete machine driving tractive force in conjunction with the output torque of selected HM Hydraulic Motor, calculate the required engagement diameter of drive wheel, with this reference diameter d as drive wheel.By this diameter value,, obtain the involute of this drive wheel thus according to gear involute method of deploying.According to requirement of strength, calculate the tooth depth of the drive wheel gear teeth 2.According to the tooth depth of the gear teeth 2, intercept the line style of cooresponding one section involute as the drive wheel gear teeth 2 mates 202, its tooth top part 201 adopts arc transition to get final product with tooth root part 203.
Because the mate 202 of the gear teeth 2 is an involute shape in the utility model, so when engaging-in two formed neutral gears of caterpillar block, be similar to the gear motion of rack-and-gear, reduced impact engaging-in, that produced when nibbling out of the linear pattern drive wheel gear teeth and relatively friction, make in the whole walking process engagement steadily, link up.
Claims (1)
1. a track sprocket comprises the wheel body and the gear teeth, and wherein the gear teeth comprise the tooth top partial sum tooth root part of circular arc, and the mate between tooth top partial sum tooth root part, and it is characterized in that: described tooth mesh partly is involute shape.
