Abstract

The utility model provides a novel exciter for a vibrating screen, which has good sealing performance and rapid heat dissipation. The novel exciter for the vibrating screen comprises a box body (1), a bearing gland (2), a labyrinth seal ring (3) and the like, and is characterized in that a long shaft (7) and a short shaft (9) are arranged in the box body (1) of the novel exciter for the vibrating screen, and the long shaft and the short shaft are respectively provided with a left-handed gear (13) and a right-handed gear (14). The novel exciter for the vibrating screen has a light structure, good sealing performance, rapid heat dissipation, no oil leakage, high durability and reliability and high cost performance and is capable of continuously running at high frequency. The fitting surfaces of the exciter are respectively and precisely processed by adopting a numerical control machine before being assembled, thereby, the entire assembling quality of the vibrating screen is effectively ensured, and then, a vibrating screen body is fastened according to a specified tightening torque by adopting a high-quality bolt and adopting an advanced clean seal assembling process.

Description

The novel vibrating screen vibrator

Technical field

The utility model relates to a kind of vibrator, relates in particular to a kind of novel vibrating screen vibrator.

Background technology

Along with improving constantly of bolting specification requirement, the vibrator that presses for a kind of super large exciting force and safety coefficient, overlength service life is applied to vibratory sieve.Because the vibrator development time that at present domestic producers make is short, with low content of technology, manufacture level is poor; In time do not improve and improve; Product can not satisfy higher instructions for use; So mostly coal preparation plant selects the more excellent imported product of quality for use, but expensive eventually, delivery cycle is also longer.Be raising China equipment manufacture technical merit, surpass the advanced, the technological innovation of vibratory sieve vibrator is imperative.

Summary of the invention

According to above technical problem; The utility model provides the novel vibrating screen vibrator of a kind of good seal, rapid heat dissipation;, oil stifled sealing gasket 17 stifled 16 by casing 1, bearing gland 2, labyrinth seal ring 3, centering block 4, balancer shaft 5, centering block gland 6, major axis 7, centering block separation sleeve 8, minor axis 9 oil baffle disc A10, bearing 11, oil baffle disc B12, left-handed gear 13, dextrorotation gear 14, outside framework oil seal 15, magnetic oil, Box Cover 18, Box Cover pad 19, gear separation sleeve 20, oil-sealing sleeve 21, respirator 22 are formed; It is characterized in that a major axis and minor axis are arranged in the utility model casing; Left-handed gear and dextrorotation gear are housed respectively on the axle; Respectively there is a bearing gear both sides; The bearing outside has oil baffle disc, oil-sealing sleeve, labyrinth seal ring, centering block separation sleeve, centering block and balancer shaft etc. successively, and stifled, oily stifled sealing gasket of magnetic oil and respirator are equipped with in the casing outside.

The beneficial effect of the utility model is: what its sophistication of the utility model specialty was made is efficient toward the afterburning box vibrator of complex line; Such vibrator adopts the special vibrating bearing of the up-to-date development of SKF; Gear housing is manufactured meticulously, light in structure, good seal, rapid heat dissipation, oil-proof, durable reliable, and cost performance is high; But high frequency turns round continuously; Centering block is provided with multiple chock filling mode, and the eccentric moment or the exciting force of big parameter capable of being combined satisfy the different vibration indexs and the requirement of use, are applicable to all kinds of vibratory equipments.Adopt the splash lubrication mode, select the high-grade lubricating oil of world's famous brand for use, improve the result of use and the life-span of equipment greatly.Adopt magnetic drain plug with the iron filings in the in good time absorption gear lubricant, improve oil quality, and be provided with special respirator.The vibrator mating surface all adopts Digit Control Machine Tool to carry out Precision Machining before assembling, guarantees the whole assembly quality of screen(ing) machine effectively.Select the high-quality bolt then for use, adopt advanced cleaning sealing assembly technology that sieve nest is fastening by the clamp load torque of regulation.

The specific embodiment

In conjunction with Fig. 1, Fig. 2, shown in Figure 3, the utility model is further specified

Bearing 11 is pressed into casing 1; Put into gear separation sleeve 20 above, left-handed gear 13, dextrorotation gear 14 are placed between the gear separation sleeve and align, be pressed into major axis 7 and minor axis 9 respectively;

Oil baffle disc

10 and 12 is installed; Bearing gland 2 assemblies that outside framework oil seal 15 and labyrinth seal ring 3 are housed are fixed on the casing through major axis and minor axis,, keep sealing to prevent the leakage of gear oil.The centering block separation sleeve 8 of on major axis, packing into; Loading onto centering block 4 at major axis and minor axis axle head respectively utilizes the different arrangement forms of balancer shaft 5 to obtain different excitation; With centering block gland 6 that centering block 4 is fixing, load onto Box Cover pad 19 and Box Cover 18, minor axis one side is loaded onto respirator 22 near the end-face helical hole of Box Cover outside casing; Screwing with the stifled sealing gasket 17 of magnetic oil stifled 16 and oil and press tight dress in other end-face helical holes, can use after injecting gear oil and the test passes of regulation oil number and oil mass.
