Problems solved by technology

[0002] At present, the rotation of the power output shaft of many mechanical equipment drives the load to move. When the load movement is blocked due to some faults, the power output shaft cannot drive the load to move, and overload occurs.
At this time, if the power output shaft continues to transmit the load, it will cause damage to the power source that drives the power output shaft. For example, the overload of the drive motor will burn out, and it will also cause damage to the transmission shaft, resulting in greater losses.

Embodiment Construction

[0018] Such as figure 1 , figure 2 , Figure 4 As shown, the present invention provides a transmission device that prevents the drive shaft from being able to stop the transmission when an overload occurs. The device is mainly composed of a transmission block 1, a transmission shaft 3, a sensing slider 4 and a reed 2. An external thread 31 is provided on the transmission shaft 3, and a chute is provided on the front end of the transmission block 1. In this embodiment The chute in is set as a dovetail slot. At the same time, the chute can also be set as a T-shaped slot. When it is set as a T-shaped slot, the corresponding sides of the sensing slider are bosses that match the T-shaped slot. The slider is slidably arranged in the T-shaped slot through the boss. The corresponding two sides of the sensing slider 4 are slopes compatible with the dovetail groove, the sensing slider 4 is slidably arranged in the dovetail groove through the slope, and a transmission shaft with a di...

Abstract

The invention relates to an anti-overloading transmission device of a power output shaft. The anti-overloading transmission device comprises a transmission shaft, a transmission block, a sensing sliding block, an internal thread block and a leaf spring. An external thread is arranged on the transmission shaft. A transmission hole with the diameter larger than that of the transmission shaft is arranged on the sensing sliding block. The sensing sliding block is arranged on the transmission block in a slidable mode. An internal thread matched with the external thread on the transmission shaft is arranged on the internal thread block. The internal thread block is arranged on the wall of the transmission hole. The leaf spring is arranged on the transmission block. The elastic free end of the leaf spring presses the sensing sliding block to move towards one side of the transmission shaft. Engagement transmission is performed on the internal thread block and the transmission shaft through the internal thread and the external thread, and the transmission block is driven to move. When transmission of the transmission block is larger than torque transmitted by engagement of the internal thread and the external thread, the transmission shaft idles. The anti-overloading transmission device has the advantages that overload damage of a power source caused when the transmission shaft is clamped due to engagement and cannot rotate is avoided, and damage to the transmission shaft is avoided.

Description

technical field [0001] The present invention relates to the field of overload protection for a power output shaft, in particular to a transmission device for preventing overload of a power output shaft. Background technique [0002] At present, the rotation of the power output shaft of many mechanical equipment drives the load to move. When the load movement is blocked due to some faults, the power output shaft cannot drive the load to move, and an overload phenomenon occurs. At this time, if the power output shaft continues to transmit the load, the power source that drives the power output shaft will be damaged, such as the overload of the drive motor burns out, and the transmission shaft will be damaged at the same time, thereby causing a large loss. Contents of the invention [0003] The purpose of the present invention is to provide a power output shaft overload prevention transmission device that can prevent the transmission shaft from stopping when overload occurs, ...
