Abstract
The utility model belongs to vibrating machine assemblies and particularly relates to a vibration exciting block which is used for a vibrating exciter of a vibration screen. The vibration exciting block is assembled on a vibrating motor shaft. The vibration exciting block is characterized by being composed of a balance weight block, a taper sleeve, an eccentric block, a tensioning sleeve and bolts, wherein the taper sleeve is welded to the upper end of the eccentric block, the balance weight block is welded to the lower end of the eccentric block, and the taper sleeve and the tensioning sleeve are fixed through the bolts. The vibration exciting block is novel in design and simple and reasonable in structure. Due to the fact that the taper sleeve and the eccentric block are welded into a whole after boss type matching is applied to the taper sleeve and the eccentric block, the relative positions and overall firmness are guaranteed in the process of welding. Due to the fact that the balance weight block is additionally welded, the requirement for the balance weight needed by the vibration exciting block is met and the problem that the overall design weight is large is solved.
Description
Technical field
The utility model belongs to the vibrating machine assembly, is specially the exciting piece for exciter for vibration screen.
Background technology
Vibratory sieve is widely used in the graded operation of the industrial departments such as mine, ore dressing, coal separation, building materials, chemical industry, and the exciting piece is the main working parts of vibratory sieve, is loaded on the vibrator.Usually the pilot hole of exciting piece is straight hole, with cooperating of vibrator main shaft be interference fits (comprising the cooperation of gap or interference).After exciting piece and the spindle mounted, or cooperated pine, or cooperate tension: cooperated pine can not guarantee instructions for use, and easily damaged in the use procedure, service life is short; Cooperate tension to cause the dismounting difficulty, Maintenance and Repair are inconvenient, and inefficiency can't guarantee the secondary assembly quality.
Summary of the invention
To be solved in the utility model is exactly that pine or tension are crossed in the assembling that has the exciting piece now, can't guarantee the problem of assembly quality, working service inconvenience, a kind of easy disassembling is provided, can guarantees easily exciting piece of assembly quality, working service.
Exciting piece of the present utility model, be assemblied on the shock electric machine axle, it is characterized in that being comprised of balancing weight, tapered sleeve, eccentric block, tensioning sleeve and bolt, tapered sleeve is welded in the upper end of eccentric block, balancing weight is welded in the lower end of eccentric block, and tapered sleeve and tensioning sleeve are fixed with bolt.Balancing weight is used for strengthening the eccentricity of eccentric block, strengthens exciting force.
Described eccentric block is provided with bolt hole, and is welded with bolt in the bolt hole position, in order to the equipment operation, when exciting force is inadequate, joins adjustable pouring weight but secondary adds.
Described eccentric block upper end is concave station with the position of tapered sleeve assembling, guarantees the welding position of tapered sleeve.
Described eccentric block top is provided with screwed hole, does lifting.
Described tapered sleeve Excircle machining becomes boss-shaped, and endoporus is bellmouth, and the macropore end margin place of the bellmouth of tapered sleeve is provided with threadless half bolt hole and two half-thread holes of three; Tensioning sleeve is the straight hole with keyway, and its cylindrical is taper, and there are three half-thread holes and two threadless half bolts hole in the large end margin place of taper; Tapered sleeve and tensioning sleeve are integrated by bolts assemblies.The bolt hole of tapered sleeve and the pairing of the screwed hole of tensioning sleeve are used for that the screwed hole of tapered sleeve is installed and the bolt hole of tensioning sleeve matches, and are used for dismounting.
For ease of assembling, the endoporus of tensioning sleeve is provided with the groove of 2mm to outer surface.
Exciting piece of the present utility model, novel in design, simple and reasonable for structure, tapered sleeve and eccentric block are welded as a whole after adopting projective table type to cooperate, relative position when having guaranteed welding and whole fastness, the balancing weight that adds weldering, namely satisfy the required counterweight of exciting piece, also exempted the large problem of global design weight.

The specific embodiment
Embodiment 1: a kind of exciting piece, be assemblied on the shock electric machine axle, be comprised of balancing weight 5, tapered sleeve 3, eccentric block 4, tensioning sleeve 6 and bolt, tapered sleeve 3 is welded in the upper end of eccentric block 4, balancing weight 5 is welded in the lower end of eccentric block 4, and tapered sleeve 3 and tensioning sleeve 6 usefulness bolts are fixed.Balancing weight 5 is used for strengthening the eccentricity of eccentric block 4, strengthens exciting force.Eccentric block 4 is provided with bolt hole, and is welded with bolt in the bolt hole position, in order to the equipment operation, when exciting force is inadequate, joins balancing weight 5 but secondary adds.The position of eccentric block 4 upper ends and tapered sleeve 3 assemblings is concave station, guarantees the welding position of tapered sleeve 3.Eccentric block 4 tops are provided with screwed hole, do lifting.Tapered sleeve 3 Excircle machinings become boss-shaped, and endoporus is bellmouth, and the macropore end margin place of the bellmouth of tapered sleeve 3 is provided with threadless half bolt hole 2 and two half-thread holes 1 of three; Tensioning sleeve 6 is the straight hole with keyway, and its cylindrical is taper, and there are three half-thread holes 1 and two threadless half bolts hole 2 in the large end margin place of taper; Tapered sleeve 3 and tensioning sleeve 6 are integrated by bolts assemblies.The screwed hole pairing of the bolt hole of tapered sleeve 3 and tensioning sleeve 6 is used for that the screwed hole of tapered sleeve 3 is installed and the bolt hole of tensioning sleeve 6 matches, and is used for dismounting.For ease of assembling, the endoporus of tensioning sleeve 6 is provided with the groove of 2mm to outer surface.After vibrating motor started, the exciting piece was made circular motion with motor, in the process that falls, gravity when utilizing the object free-falling, together drive the exciter mass vibrating with motor, purpose is the power of exciting source at the beginning of minimizing equipment when operation, the good effect that reach energy-conservation, subtracts consumption.
