Along with China's rapid economy development and continuous advancement in technology, industries such as coal, metallurgy, chemical industry, building materials, mine, water power press for high throughput and vibratory sieve efficiently, sieve, dehydration, de-mediated and graded operation, as the vibrator of vibratory sieve heart become that the restriction vibratory sieve maximizes, one of bottleneck of high efficiency.Present widely used vibrator adopts eccentric block external overall structure, has lubricated concentrated, easy to maintenance, the characteristics that manufacturing cost is lower of in light weight, compact conformation, driving member, and is more popular with users.But there is following defective in above-mentioned vibrator: (1) lubricating system is grease lubrication, causes the oiling number of times frequent, and axially leakage of oil seriously waits inconvenience.(2) lubricant grease is too much or very few in the bearing chamber, does not have best bearing lubrication state, has greatly shortened the service life of bearing.(annotate: it is optimum state that the lubricating grease charging quantity accounts for the inner 1/3-2/3 of bearing, surpasses bearing with oily loading or oil-poor, will cause bearing temperature too high).(3) when the vibrator continuous operation, bearing temperature height when rotating at a high speed, oil viscosity is rotten, and lubricant effect is not good, causes bearing short service life, the maintenance cost height.
Three, utility model content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of modern design, high lubricating effect, long service life, the anti-effective constant temperature energy-saving thin oil vibrator of axial leakage of oil are provided.
The technical solution of the utility model is:
A kind of constant temperature energy-saving thin oil vibrator, contain power transmission shaft and bearing block, two self-aligning bearings are installed between the two, and described power transmission shaft two ends are disposed with bearing chamber end cap, labyrinth lid and eccentric block from inside to outside, and described bearing chamber end cap is provided with the axle oil envelope, be provided with spacer ring between described two self-aligning bearings, described bearing block upper end is provided with oil inlet pipe, and this oil inlet pipe runs through described bearing block body wall and described spacer ring, and its inner end is equipped with atomizer; Described power transmission shaft between described self-aligning bearing and the described bearing chamber end cap is provided with at least one circle ring oiler; Described bearing chamber lower end inner surface is provided with axial back oil road, this back oil road middle part can be communicated with scavenge oil pump by the spill port that runs through described bearing chamber lower end body wall, its two ends are communicated with chamber between described self-aligning bearing and the described bearing chamber end cap by the radially oil-recovery tank on the ring surface in the described bearing chamber end cap, are convenient to the oil that ring oiler dishes out and flow into described back oil road.
Described power transmission shaft between described self-aligning bearing and the described bearing chamber end cap is provided with two circle ring oilers, and this ring oiler is an annular groove, and its cross section is an arc.
The beneficial effects of the utility model are:
1, the utility model modern design is utilized material rotating centrifugal principle, establishes ring oiler on power transmission shaft, the lubricating oil on the power transmission shaft is thrown on the inner peripheral wall of bearing chamber end cap, stops fluid to power transmission shaft two ends draining, thereby anti-axial leakage of oil is effective.
2, the utility model is thrown in the back oil road of the suitable sidewall inflow of the oil bearing chamber foot on the end cap inner peripheral wall by ring oiler, flows back to fuel tank by scavenge oil pump, cooler, filter then, by the circulation fuel feeding, has controlled level height on the one hand; Take away the certain heat in the bearing chamber on the other hand, bearing temperature is reduced, reached good lubricated cooling effect.
3, the utility model adopts the oil spout mode to provide lubricated to bearing, and high lubricating effect, and lubricating oil again through filtering, can be removed abrasive particle and introduced contaminants in cyclic process, reduce wearing and tearing prolongs bearing service life greatly, has reduced maintenance cost.
4, the utility model is applied widely, can be applicable to multiple vibratory sieve, is easy to promotion and implementation, has good economic benefit.
Four, description of drawings:
Fig. 1 is the structural representation of constant temperature energy-saving thin oil vibrator;
Fig. 2 is an A shown in Figure 1 place enlarged drawing.
Five, the specific embodiment:
