Abstract
The invention discloses a columnar vibration excitation device, which comprises a transmission shaft and at least two pairs of eccentric blocks, wherein the eccentric blocks are linearly connected with and mounted inside a hollow columnar shell; a fixed sealing flange is arranged at one end of the shell, and a through hole flange is arranged at the other end of the shell; a bearing is arranged on the transmission shaft on each of the two sides of each eccentric block; the transmission shaft with the eccentric blocks and the bearings is inserted into the shell through an oil seal from one end of the through hole flange; a fixing bolt is arranged between the shell and the outer wall of each bearing; at least one shaft coupling is connected to the middle part of the transmission shaft when a plurality of pairs of eccentric blocks are combined in the shell. According to the columnar vibration excitation device, the eccentric blocks and the transmission shaft are arranged in the hollow columnar shell in a sealing way, the columnar vibration excitation device is strong in vibration strength, complete in lubrication and low in bearing abrasion speed, lubricating oil is difficult to leak, the maintenance workload of the device can be effectively reduced, and the service life can be prolonged.
Description
Technical field:
The present invention is a kind of cylindricality exciting device being applicable to that vibratory equipment is installed and used.
Background technology:
At present, the exciting device that the vibrosieve or load transfer device of the industry widespread uses such as mine, iron and steel, chemical industry, food, building are installed, is all on a transmission shaft, is evenly equipped with a pair eccentric block.During use, transmission shaft is arranged on vibratory equipment, implements vibration by driven by motor transmission shaft.Existing exciting device is not owing to being transmission shaft and eccentric block sealing are arranged in a housing, so ubiquity is short for service life, care work amount is large, installs inconvenient shortcoming.
Summary of the invention:
The object of this invention is to provide a kind of maintenance workload little, long service life, cylindricality exciting device easy for installation.
Technical scheme of the present invention completes as follows, cylindricality exciting device, it includes transmission shaft and eccentric block, it is characterized in that: have at least two pairs of eccentric block straight lines to be mounted in a hollow cylindrical outer cover, a closed attachment flange is provided with in one end of shell, a through hole flange is provided with at the other end of shell, the transmission shaft of each eccentric block both sides is separately installed with a bearing, transmission shaft with eccentric block and bearing inserts in shell from through hole flange one end through oil sealing, between shell and each bearing outer wall, have bolt of rear end plate respectively.In the middle of transmission shaft, at least one coupler is connected with when being combined by multipair eccentric block in housing.
Multipair eccentric block and drive shaft seal are enclosed in the tubular shell of a hollow by the present invention, have vibration intensity strong, and fully, wear-out of a bearing speed is slow, and lubricating oil not easily leaks, and effectively can reduce the maintenance workload of equipment for lubrication, improves service life.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention.
Detailed description of the invention:
Describe embodiment in detail by reference to the accompanying drawings, transmission shaft 3 and eccentric block 4 are the present invention includes, main improvements have at least two pairs of eccentric blocks to be jointly arranged in a hollow cylindrical outer cover 6, a closed attachment flange 1 is provided with in one end of shell, a through hole flange 8 is provided with at the other end of shell, the transmission shaft of each pair of eccentric block both sides is separately installed with a bearing 2, transmission shaft with eccentric block and bearing inserts in shell from through hole flange one end through oil sealing 9, between shell and each bearing outer wall, have bolt of rear end plate 7 respectively.In the middle of transmission shaft, at least one coupler 5 is connected with when being combined by multipair eccentric block in housing.
It is simple that the present invention has technique, easy to process, only need several conventional machining equipment just can complete, powerful vibratory force required when namely the combination of multipair eccentric block and bearing can produce work in housing, the load that single bearing bears can be reduced again to greatest extent, reduce the rate of wear of bearing; In lubrication, the flange through hole due to transmission shaft input end is hermetically-sealed construction, effectively can control lubrication leakage, can reach the object extending exciting device service life and alleviate maintenance.
