Novel vibration exciter

Abstract

The invention discloses a novel vibration exciter. The novel vibration exciter comprises a gear box and a bracket, wherein a first bevel gear and a second bevel gear which are meshed with each other are rotationally arranged in the gear box through bearings, the two side faces of the first bevel gear and second bevel gear are circumferentially provided with symmetrical grooves of which the numberis even number, the grooves are internally provided with first eccentric blocks and second eccentric blocks, and a rotating shaft of the second bevel gear penetrates through an end cover of the gear box, extends to the outer portion of the end cover and is connected with a driving belt wheel. The novel vibration exciter has the advantages that the first eccentric blocks and the second eccentric blocks are embedded in the first bevel gear and second bevel gear, thereby shortening the length of a transmission shaft, so that the entire size is impact, the volume is greatly reduced, inner space ofthe gear box is effectively utilized, the installation positions and numbers of the first eccentric blocks and second eccentric blocks can be flexibly adjusted, thereby generating vibration excitingforce with different effects, so that different use requirements are met, and various product series can be developed by adopting a same structure and size, thereby saving the cost.

Description

technical field [0001] The invention relates to the field of vibrating devices, in particular to a novel vibrator. Background technique [0002] The exciter is a device attached to some machinery and equipment to generate excitation force, and is an important part of using mechanical vibration. The vibrator can make the excited object obtain a certain form and size of vibration, so as to perform vibration and strength tests on the object, or to calibrate vibration testing instruments and sensors. [0003] Ordinary inertial vibrator, the eccentric block is arranged on the transmission shaft, and placed outside the gearbox, so another box needs to be installed outside the gearbox, resulting in a large axial dimension of the entire vibrator, which is relatively cumbersome , At the same time, because the eccentric block is placed outside the gearbox, the speed of the transmission shaft is very fast when the exciter is working. Once a safety accident such as a drive shaft breaks...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a new type of exciter, which solves the problems of large size and bulkiness of the traditional exciter, easy breakage of the transmission shaft or flying out of the eccentric block
