Synchronous double-eccentric-shaft shock excitation device and thin oil lubrication method

Abstract

The invention relates to the technical field of vibration excitation devices, in particular to a synchronous double-eccentric-shaft shock excitation device and a thin oil lubrication method. The device comprises a base, an eccentric shaft, a first oil tank, a second oil tank, a synchronous gear and an oil flinger, wherein the first oil tank and the second oil tank are arranged at the two ends of the eccentric shaft respectively, the synchronous gear is arranged in the first oil tank, and lubricating oil in the first oil tank splashes to lubricate a bearing through the synchronous gear; the oilflinger is arranged in the second oil tank and enables lubricating oil in the second oil tank to splash to lubricate the bearing; an eccentric part of the eccentric shaft is positioned outside the oil tank and rotates without hindrance, so that the working loss is low; and compared with a single large oil tank, the two small oil tanks are adopted to realize the condition that the sufficient lubricating effect can be guaranteed through a small amount of lubricating oil, the good sealing design can be achieved, and leakage is avoided. The synchronous gear and the oil flinger are matched with the design of an upper oil way, oil way circulation in the oil tank can be achieved without external power, and sufficient lubrication is achieved.

Description

technical field [0001] The invention relates to the technical field of vibration devices, in particular to a synchronous double eccentric shaft vibration device and a thin oil lubrication method. Background technique [0002] With the rapid development of the existing industrial level, a large number of feeders will be used in the external transportation of mining, metallurgy, chemical and other industries. The existing feeders generally use vibration exciters to make materials run. It rotates at high speed, so the bearings need to be well lubricated. [0003] The authorized announcement number is CN 201567049U, which discloses a Chinese patent with external drive biaxial vibrator, which includes a biaxial vibrator, which is characterized in that: two eccentric shafts are installed in parallel in a housing, and the same ends of the two eccentric shafts are respectively installed with A transmission gear meshing with each other, thin oil in contact with the lower part of the...

AI Technical Summary

Problems solved by technology

The existing double eccentric shaft vibration device is lubricated with thin oil, which has a significantly improved lubricating effect compared with paste lubricating oil. However, due to the use of a single large oil tank, more lubricating oil is required, and more lubricating oil is harmful to the The sealing effect is higher, and the problem of lubricating oil leakage is prone to occur; the eccentric part of the eccentric shaft is in the oil tank, and when the eccentric shaft rotates, the lubricating oil forms resistance to the eccentric part, thus increasing the energy consumption loss of equipment operation
