Description
[technical field]
The utility model relates to a kind of vibrating motor, refers to the large span vibrating motor especially.
[background technology]
The large span vibration generator can improve separating effect and improve fractional dose, and especially at oil industry, the vibration generator of large span helps improving mud capacity and solid-liquid separation effect.
Aspect stressed:
(1) existing internationally renowned brand---the shock electric machine of U.S. Martin's engineering company, its structure as shown in Figure 1, essence is brachmorphy shock electric machine 1 ' and the combination that adds long cylinder 2 ' supporting, the method that is adopted is to add long support at the two ends of short motor 1 ' with cylinder 2 ', but still kept short motor 1 ' original stress basically, thereby, to there not being great influence the useful life of lacking motor 1 ' basically, but, owing to increased the supporting cylinder 2 ' at two ends, its quality just increases greatly, and when further requiring increasing and compass screen surface further to require broadening along with exciting force simultaneously, its additional mass also will increase greatly.
(2) existing home brands---the microscler shock electric machine of a lot of companies, its structure as shown in Figure 2.Because the increase of span, for guaranteeing that axial amount of deflection is in allowed band, must increase motor vibrating shaft 1 " rigidity; therefore; the multi-support 2 of having to adopt " structure of axle, multi-support 2 appears so unavoidably " redundant structure of axle; and as shown in Figure 3; twice redundant structure beam; its stressing conditions is very unfavorable, this structure all is very high to manufacturing, installation and instructions for use, all is difficult to guarantee when static load; be still more on the vibrating machine under the strong machinery noise background, its dynamic load stressed just more abominable.When exciting force further required increasing and compass screen surface further to require broadening, problem was just more outstanding.
Aspect the exciting force adjustment:
(1) existing external large span vibrating motor, structural representation as shown in Figure 1, vibrating motor need be taken apart and could adjust exciting force, waste time and energy, and both sides support footing installed surface requires high: when adjusting, at first need unclamp the mounting screw of vibrating motor on equipment, the vibrating motor slave unit is removed, take support apart, unclamp the adjustable eccentric piece and tighten screw, realize the stepless adjustment of exciting force, refill the both sides support, and must guarantee that the both sides footing at same horizontal plane, is contained in vibrating motor on the equipment again, the set-up procedure trouble, require high, labour intensity is big, and efficient is low.Because the shorter vibrating motor weight of large span vibrating motor is big, the power of generation is big, if the both sides adjustment has deviation, then motor very easily damages, so require exciting force to adjust the precision height; Require vibrating motor installation accuracy height on the other hand, if two support foot stationary planes are the dotted line contact, then local pressure is bigger, very easily makes securing member damages such as screw, causes motor to drop; To sum up the client difficulty finish this type of large span vibrating motor exciting force adjustment.
(2) existing domestic large span vibrating motor, structural representation can not be adjusted according to the required exciting force of client as shown in Figure 2.
Because large span vibrating motor major part is by motor housing base or the base that adds long cylinder shock electric machine to be installed on the screen box, the quality of shock electric machine integral body is often all very big, be difficult to further alleviate, can not satisfy vibrating screen especially the balanced elliptic inertia vibrating screen to the requirement of microscler shock electric machine.On the other hand,, do not satisfy needs, the use of the vibration generator of large span is restricted producing because the client is difficult to maybe can not adjust the exciting force of large span vibrating motor.
[utility model content]
The technical assignment of the technical problems to be solved in the utility model and proposition is that the prior art scheme is improved and improved, a kind of three-section vibration motor eccentric block vibrator is provided, to improve electric machine main shaft stressed to reach, and improves power matter ratio, and the power that is excited at the same time regulates accurately, purpose easily.For this reason, the utility model is taked following technical scheme:
Three-section vibration motor eccentric block vibrator, comprise the overhanging electric machine main shaft of tool fire-proof motor, fixed eccentric block, adjustable eccentric piece, in be provided with the fire-proof motor container cavity casing, be symmetrically set in the support of casing both sides, it is characterized in that: described electric machine main shaft two ends are connected with two eccentric shafts, one end that is provided with fixed eccentric block and adjustable eccentric piece by soft shaft coupling respectively, and the eccentric shaft other end is connected with support by bearing and the bearing pedestal that is coated at bearing; Fixed eccentric block is positioned at the inboard of bearing pedestal; Described adjustable eccentric piece is positioned at the outside of bearing pedestal, and it is clamped in outer stretching on the eccentric shaft of support by connector.Electric machine main shaft and eccentric shaft adopt and are flexible coupling, and processing and matching requirements are low, cut down finished cost, and easily realize producing in batches, and installation and removal are conveniently raised the efficiency and reduced cost.Compare present elongated shape vibrating motor weight saving 20% nearly, it is about 10% that volume reduces, and improves power matter ratio.The adjustable eccentric piece is positioned at the outside of bearing pedestal, and stretch in support outward, be convenient to the adjustment of exciting force, when adjusting, need not to pull down motor, needn't take casing and support apart, as long as unclamp connector, can just adjust the relative position of adjustable eccentric piece and fixed eccentric block, adjust directly perceived, visual, effectively improve the precision of adjusting, guaranteed the reliability of machine operation, the useful life of effectively improving motor, can not occur because of injustice is installed because of adjusting exciting force, contact-making surface is little, and the stressed situation that causes motor to drop has greatly effectively solved the long motor of three-section vibration difficult technologies difficult problem aspect the exciting force adjustment.And initiatively eccentric block and driven eccentric block are contained in the inboard and the outside of bearing respectively, and are beneficial to the stressing conditions that improves bearing, reduce the amount of deflection of eccentric shaft, reduce because of deflection deformation brings axial thrust load, prolong the life-span of equipment.
As the further of technique scheme improved and replenish, the utility model also comprises following additional technical feature:
The described support outside is provided with end shield, has received described adjustable eccentric piece in the end shield, and the outer face of eccentric shaft affixed is used to represent the direction board of exciting force percentage.End shield plays a part to keep the vibrating motor cleaning inside, prevents that dust, rainwater etc. from entering, and avoids line, ribbon to twine.Exciting force is easy to adjust, and vibrating motor does not need to remove on the slave unit, only need take the both sides end shield apart, unclamp the adjustable eccentric piece and tighten screw, realizes the stepless adjustment of exciting force, tightens adjustable eccentric piece screw, and the dress end shield is just finished the adjustment of exciting force.
