Abstract
The utility model relates to a safety device of a transmission shaft, which comprises a power input end and a power output end of the transmission shaft. The power input end is connected with a power input portion of a device; load bearing portions of the device are connected by the aid of the power output end; and a dangerous section with a diameter smaller than that of the transmission shaft is arranged between the power input end and the power output end. When a system works abnormally and surpasses the designed maximum allowable value, the transmission shaft is broken at the position of the dangerous section with the smaller diameter, and no power is inputted to the inside of the system, so that accessories and transmission parts are protected from damage.
Description
Technical field
The utility model relates to a kind of safty device of transmission shaft.
Prior art
Along with the development of technology, power and rotating speed that machine driven system is transmitted are also increasing, and the power requirements that can transmit machine driven system is more and more higher.The existing mechanical transmission system lacks the measure of protecting it not to be damaged satisfying the more powerful while of transmission when system works is unusual for important accessory.Under the situation that internal system breaks down, outside input power also continues by transmission shaft to the internal system transmission, therefore can cause contents and transmission part to be subjected to bigger damage.
Summary of the invention
Goal of the invention
To be that invention is a kind of can occur when intentional the device of annex and transmission part in the automatic protective system in system to the purpose of this utility model.
Technological scheme of the present utility model is: device comprises the power input end and the power take-off of transmission shaft, the power input end connects with the power input part of equipment, by the bearing part of power take-off connection device, be provided with the dangerouse cross-section of one section diameter between the input end of described power and the output terminal of power less than the transmission shaft diameter.
The utility model is provided with the dangerouse cross-section of one section minor diameter between the power input end of transmission shaft and output terminal; therefore when the internal system operation irregularity; surpass design maximum allowable value; transmission shaft fractures at the dangerouse cross-section place of minor diameter; internal system does not have the power input, thereby protection annex and transmission part are not damaged.
Description of drawings
Fig. 1 is insurance axle schematic representation.
Embodiment
As shown in the figure, device comprises the power input end 1 and the power take-off 2 of transmission shaft, the power input end connects with the power input part of equipment, by the bearing part of power take-off connection device, be provided with the dangerouse cross-section 3 of one section diameter between the input end of described power and the output terminal of power less than the transmission shaft diameter.
Claims (1)
1. the safty device of a transmission shaft, it is characterized in that, device comprises the power input end (1) and the power take-off (2) of transmission shaft, the power input end connects with the power input part of equipment, by the bearing part of power take-off connection device, be provided with the dangerouse cross-section (3) of one section diameter between the input end of described power and the output terminal of power less than the transmission shaft diameter.
