Abstract
The utility model discloses an excitation device, it includes the epaxial upper and lower eccentric piece of main shaft, characterized by, and the main shaft dress in the oscillator section of thick bamboo is in the bearing frame, and is fixed with the flange between bearing frame and the oscillator section of thick bamboo. It has the advantages of simple structure, raw material saving, firmness, difficult loosening and the like.
Description
The utility model relates to a kind of novel exciting device, and it is widely used on the vibratory sieve.
Existing exciting device, mostly be to adopt oscillator and oscillator seat separate type, by the briquetting of taper oscillator is pressed in during assembling that its shortcoming is on the conical surface of oscillator seat: oscillator and upper and lower gripper shoe are all very heavy, material and power consumption are big, complex structure, the machining accuracy height is difficult for ensuring the quality of products, need adjust concentricity during installation, assembly technical requirement is high.
The utility model is at above-mentioned shortcoming, proposes a kind of simple in structurely, saves material well-set a kind of exciting device.
Task of the present utility model is finished like this, it comprises last eccentric block and following eccentric block on the main shaft, feature is: the main shaft in the oscillator tube is contained in the bearing block, fixes with flange between bearing block and the oscillator tube, in order to prolong the service life of bearing and main shaft, on bearing block, be added with the bearing door.
The utlity model has following effect: it is simple in structure, saves material about 30%, and the parts simple shape does not need very high machining accuracy, and sound construction is difficult for advantages such as loosening.
Accompanying drawing 1 is a structural representation of the present utility model.
Describe embodiment in detail in conjunction with above accompanying drawing, oscillator tube 2 is contained in 4 li of bearing blocks, and the bearing door is arranged on the bearing block 4, in order to avoid pollute.Main shaft respectively has upper and lower eccentric block 1,6 in two ends about in the of 5, is fixed together with flange 3 between oscillator tube 2 and the bearing block 4, at oscillator tube 2 two ends pallet 7 is arranged, and on the pallet 7 vibratory sieve is housed.
Claims (2)
1, a kind of exciting device, it comprises upper and lower eccentric block on the main shaft, it is characterized in that: the main shaft in the oscillator tube is contained in the bearing block, fixes with flange between bearing block and the oscillator tube.
2, a kind of exciting device according to claim 1 is characterized in that: be added with the bearing door on the bearing block.
