Problems solved by technology

However, some transmission mechanisms have design deficiencies, which are limited by the size of the shaft step during design, resulting in a smaller shaft diameter and insufficient torque transmission between the shaft and the wheel. As the load increases, the joint between the wheel and the shaft is fatigued and fractured. , the shaft must continue to be replaced with a new shaft after breaking, but it will continue to break after a short period of use
As a result, the labor intensity and cost in production are increased at the same time

Embodiment 1

[0016]This example is an example of the rotation wheat scallion axle structure, such asfigure 1 In the original structure, the stepped axis 1 diameter is 70mm, the step two axis 2 is 65mm, the step two axis 2 length is 120 mm, the wheel 3 is fitted on the step two shaft 2, often appears to be a step axis 1 and the step two-axis 2 connection Fatigue breaks.

[0017]In this embodiment, a step-axis wheel structure of an increased force transfer strength does not change the diameter of the original shaft, including the step axis inserted into the inner hole and the keyway opening in the step axis and the inner hole, said The step axis is composed of a step-shaped axis 1 having a diameter of 70 mm and a step two-axis 2 having a diameter of 65 mm, and the connection is located in the inner hole of the wheel 3, the inner hole of the wheel 3 is a step of forming the shape size and a step axis outer diameter. Hole, the step bore is composed of a step-axis hole 7 with a step two-axis hole 8, and...

Embodiment 2

[0019]In the step axle gear structure of the increasing force transfer intensity described in this embodiment, each of the structures and connection relationships are the same as in Example 1, and different points are: the stepped axis 7 and the step two-axis hole. The ratio of the length of 3: 7; the stepped axis 1 has a diameter of 10 mm, and the diameter of the step two shaft 2 is 9 mm.

Embodiment 3

[0021]In the step axle gear structure of the increasing force transfer intensity described in this embodiment, each of the structures and connection relationships are the same as in Example 1, and different points are: the stepped axis 7 and the step two-axis hole. The ratio of the length of 7: 3; the stepped axis 1 is 600 mm, and the diameter of the step two shaft 2 is 550 mm.

Abstract

The invention relates to the technical field of mechanical transmission, in particular to a stepped shaft wheel train structure for increasing force transmission strength. The structure comprises a stepped shaft inserted into a wheel inner hole and a key groove formed in the stepped shaft and the wheel inner hole, the stepped shaft is formed by integrally connecting a first stepped shaft body with the larger diameter and a second stepped shaft body with the smaller diameter, the connecting position is located in the wheel inner hole, and the wheel inner hole is a stepped hole with the shape and size matched with the outer diameter of the stepped shaft. The stepped hole is composed of a first stepped shaft hole and a second stepped shaft hole, the length ratio of the first stepped shaft hole to the second stepped shaft hole is (3: 7)-(7: 3), the position and the length of a combined shaft key groove and a combined wheel key groove are the same, and the ratio of the depth of the shaft key groove to the depth of the wheel key groove is 3: 7. The shaft and wheel power transmission strength can be increased by 16-30%, and other extra cost expenditure is not increased. The structure has the advantages of high transmission torque increasing efficiency, good effect, convenient installation, high applicability and low cost.

Description

Technical field[0001]The present invention relates to the field of mechanical transmission technologies, specifically a stepped axle wheel structure of an increased force transfer intensity.Background technique[0002]With the development of society, a variety of machine equipment, the wheel and axis transmissions are commonly used in various machines. However, some in the transmission mechanism is insufficient, and in the design of the shaft step position size, the axial diameter is small, and the shaft and the rotation torque are insufficient. As the load increases, the wheel and the shaft binding part fatigue is broken. After breaking, you must continue to replace the new axis, but it will continue to break after use. Thus, labor intensity and cost in production are added.Inventive content[0003]In order to solve the above problems, the present invention provides a stepped axle structure that is simple, novel, and has a significant increase in increased force transmit strength.[0004...
