Description
[technical field]
The utility model relates to a kind of vibrating motor.
[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.
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.
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.
More than two kinds of representational existing domestic and international shock electric machines all be shock electric machine to be installed on the screen box by motor housing base or the base that adds long cylinder, thereby 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.
[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, and a kind of novel three-stage vibration motor is provided, and to improve electric machine main shaft stressed to reach, and improves power matter ratio.For this reason, the utility model is taked following technical scheme:
A kind of novel three-stage vibration motor, be provided with in comprising fire-proof motor casing, be symmetrically set in the support of casing both sides, it is characterized in that: the electric machine main shaft two ends of fire-proof motor link to each other by eccentric shaft one end that soft shaft coupling and two is provided with eccentric block, the eccentric shaft other end by side by side two bearings and the bearing pedestal that is coated at bearing link to each other with support, the support that is positioned at the bearing pedestal below is provided with the jockey that is used for affixed sieve plate.Be substituted in the structure that directly connects eccentric block on the electric machine main shaft, twice redundant structure is converted into cantilever beam and simply supported beam statically determinate structure, improved quiet, the dynamic stress situation of parts such as motor, supporting and screen box greatly, the life-span can prolong 1/3.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 employing duplex bearing is set up in parallel, and effectively improves the bearing strength of eccentric shaft.The installing hole that jockey can be Connection Block, be located on the Connection Block is connected with sieve plate to intert bolt, and jockey also can be flange etc.
As the further of technique scheme improved and replenish, the utility model also comprises following additional technical feature:
Described two bearings is clutch shaft bearing and second bearing that is positioned at the clutch shaft bearing outside; Two bearings is cylinder roller bearing, and wherein the outer ring of clutch shaft bearing is two ribs, and inner ring does not have rib; The outer ring of second bearing is two ribs, and inner ring is a single block border.Because of the axially existence of amount of deflection, on eccentric shaft, produce axial force, the clutch shaft bearing bearing radial force, second bearing gets final product bearing radial force, can bear certain axial force again.The rib of inner ring is positioned at the inboard, and when mounted, outer ring and roller are pressed into bearing pedestal, and inner ring is connected with eccentric shaft, when packing bearing pedestal into support outer ring, roller is pressed into inner ring.
Described support, bearing pedestal have the oil filler point of perforation, the inwall of bearing pedestal has the oiling groove that links to each other with oil filler point, the bearing inner shield ring that is provided with the outer back-up ring of the bearing that offsets with two outer rings between the clutch shaft bearing and second bearing and offsets with two inner rings, the outer back-up ring of described bearing have and a plurality ofly uniform draw oilhole so that oil is introduced in the bearing.Lubricating oil enters the oiling groove of bearing pedestal by the oil filler point of support, bearing pedestal, by the oilhole that draws of the outer back-up ring of bearing oil is introduced in the roller chamber of bearing then, establishes a plurality of oilholes that draw and helps the lubricated of whole circle bearing.
