Gear box applicable to high-frequency and low-frequency vibration exciter

Abstract

The invention discloses a gear box applicable to a high-frequency and low-frequency vibration exciter and relates to the field of high-frequency and low-frequency vibration equipment. The gear box comprises an excitation gear box body, a bearing block, side rib plates and a front rib plate, wherein six panels of the gear box body are fixed in a tenon positioning and thread connection manner; four through holes are formed in each of a front panel and a rear panel of the gear box, and driving shafts and driven shafts are fixed with the bearing block through bearings. The side rib plates and the front rib plate are connected and fixed with the gear box body through threads; grooves are milled in contact surfaces of all panels of the gear box body and filled with oil-resistant fluorine adhesive tapes, and the panels of the gear box body are screwed and compacted through threads in the panels; gaps between the panels of the gear box body are filled with an oil-resistant, anti-seep and anti-vibration adhesive. Compared with the prior art, the gear box overcome defects of high cost for casting and welding the gear box and poor vibration resistance. The gear box has good sealing performance, high bearing capability, good processing and assembling performance and is applicable to the high-frequency and low-frequency vibration exciter.

Description

technical field [0001] The invention relates to the field of high and low frequency vibration equipment, in particular to a gear box structure with convenient assembly and disassembly, good sealing effect and strong bearing capacity. Background technique [0002] The high and low frequency exciter is a mechanical device that provides high and low frequency composite vibrations. It is mainly used in the blanking of metal bars. It is a new green blanking method. The existing gear box structure has two methods of casting and welding. The casting type gear box is suitable for mass production, but the casting box is not suitable for high-power mechanical devices, and the welding type gear box is suitable for single-piece or small batch production. It has good processing technology and can withstand high power. It is mostly used in heavy mechanical devices, but the vibration resistance of welded gearboxes is poor. High and low frequency exciters have the characteristics of high p...

AI Technical Summary

Problems solved by technology

The existing gear box structure has two ways of casting and welding. The casting type gear box is suitable for mass production, but the casting box is not suitable for high-power mechanical devices, and the welding type gear box is suitable for single-piece or small batch production. It has good processing technology and can withstand high power. It is mostly used in heavy mechanical devices, but the anti-vibration performance of welded gearboxes is poor.

High and low frequency exciters have the characteristics of high power and severe vibration, so neither of them can be used as high and low frequency exciter gearboxes.
