Abstract
The utility model discloses cylindricality exciting device, it includes transmission shaft and eccentric block, two pairs of eccentric block straight lines are had at least 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 utility model, 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.
Description
Technical field:
The utility model 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:
It is little that the purpose of this utility model is to provide a kind of maintenance workload, long service life, cylindricality exciting device easy for installation.
The technical solution of the utility model 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 utility model, 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 utility model.
Detailed description of the invention:
Describe embodiment in detail by reference to the accompanying drawings, the utility model includes transmission shaft 3 and eccentric block 4, 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 utility model 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.
