Description

Bending-resistant testing device for multi-section transmission shaft Technical Field The utility model belongs to the technical field of transmission shafts, and relates to an anti-bending testing device, in particular to an anti-bending testing device for a multi-section transmission shaft. Background Bending resistance is an important index in industrial production for examining articles of manufacture, especially articles which need to rely on their strong rigidity in future use, and particularly important is the testing of bending resistance, such as steel for houses and bridges, because once the bending resistance of these materials is not too close, it means that they do not have sufficient strong rigidity, and it is a great potential safety hazard for future buildings to embed them. Therefore, the test of the bending resistance of the object is particularly important, in the existing industrial production, a large-scale damage experiment device is often adopted for testing the object, and the mode is time-consuming and labor-consuming in terms of device structure and cost, and is useless for the object to be tested, and losses are caused in an intangible way. Through searching, for example, chinese patent literature discloses an object bending resistance testing device (application number: 201310441867.6; publication number: CN 103487300A). The device comprises two object placing columns on a base, a U-shaped support, a transmission telescopic rod, a top block, a control module, a power supply, an information output device stepping motor and at least one ranging sensor, wherein the power supply, the information output device stepping motor and the at least one ranging sensor are respectively connected with the control module. The utility model discloses an article bending test device, although can effectually carry out bending test, and test sensitivity is high, and the effect is obvious, but the device is when bending test probably appears that the transmission shaft bending takes place the skew from putting the thing post and drops, still probably appears that pressure is too big to lead to the transmission shaft fracture, and the broken bits that jump out when the fracture probably causes personnel injury.
