Description
Technical field
The present invention relates to vibratory sieve technical field, especially a kind of vibratory sieve leak-proof arrangement.
Background technology
Conventional vibratory sieve includes frame, motor, belt driver, spindle assemblies and screen box, the electricity being fixed in frame
Machine is connected by belt driver and the spindle assemblies being arranged on screen box, and spindle assemblies include eccentric main axis, a pair of bands
The stabilizer of eccentric block, the cylinder being sleeved on eccentric main axis, the bearing block of a pair of rotational support eccentric main axis, cylinder with
The shoe cream room formed between eccentric main axis stores lubricating oil, the bearing in bearing block by shoe cream room leak through come lubricating oil
Lubrication.Vibratory sieve worked after a period of time, and people always have found that oil leakage phenomenon occurs in the end face of left and right bearing block, sometimes even
Oil leak is serious, takes bearing block apart and checks bearing (ball) cover and sealing ring, does not find any damaged and crackle.Upon examination it is found that：Originally
It is that the eccentric parts of eccentric main axis is compressed, expanded once and again in rotation process to the lubricating oil in shoe cream room, no
But the lubricating oil in shoe cream room is outwards produced a bigger extruding force, and also result in lubricating oil temperature rising, so as to
Bearing is passed to, causes bearing temperature to rise get Geng Gao, causes the lubricating grease in bearing block by solid state into liquid state, so as to form profit
The leakage of lubricating oil.
The content of the invention
The technical problem to be solved in the present invention is：Overcome deficiency in the prior art, there is provided a kind of vibratory sieve oil-leakage-prevention knot
Structure.
The technical solution adopted for the present invention to solve the technical problems is：A kind of vibratory sieve leak-proof arrangement, there is main shaft
Component, spindle assemblies include eccentric main axis, and eccentric main axis both ends are respectively equipped with stabilizer, and stabilizer is provided with eccentric block, eccentric
Main shaft both ends further respectively have the bearing block of rotational support eccentric main axis, and bearing block is arranged on sieve box of vibrating, on bearing block
Provided with lubricating grease lubricating cup, cylinder is set with eccentric main axis, cylinder both ends are connected with bearing block respectively, cylinder and bias
Shoe cream room is formed between main shaft, fixed cover is equipped with the sheath in shoe cream room, the sheath centre of gyration and cylinder on eccentric main axis
The centre of gyration is concentric.
Epoxy resin is filled with space between the sheath and eccentric main axis.
Epoxy resin is filled with space between the sheath and eccentric main axis, pvc pipe is inserted with epoxy resin.
The beneficial effects of the invention are as follows：This invention removes eccentric main axis eccentric part in rotary course in shoe cream room
The influence of lubricating oil, bearing is maintained into suitable temperature, so as to solve the problems, such as bearing block oil leak.
Brief description of the drawings
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the cross-sectional view that the present invention amplifies.
Division mark is as follows in accompanying drawing：1st, eccentric main axis；2nd, stabilizer；3rd, eccentric block；4th, cylinder；5th, sheath；6th, ring
Oxygen tree fat；7th, pvc pipe.
Embodiment
Presently in connection with accompanying drawing, the present invention is further illustrated.These accompanying drawings are simplified schematic diagram, only with signal
Mode illustrates the basic structure of the present invention, therefore it only shows the composition relevant with the present invention.
A kind of vibratory sieve leak-proof arrangement as shown in Figure 1, 2, there are spindle assemblies, spindle assemblies include eccentric main axis 1,
The both ends of eccentric main axis 1 are respectively equipped with stabilizer 2, and stabilizer 2 is provided with eccentric block 3, and the both ends of eccentric main axis 1 further respectively have rotation
The bearing block of eccentric main axis 1 is supported, bearing block is arranged on sieve box of vibrating, and bearing block is provided with lubricating grease lubricating cup, and bias is main
Cylinder 4 is set with axle 1, the both ends of cylinder 4 are connected with bearing block respectively, and oil storage is formed between cylinder 4 and eccentric main axis 1
Chamber, fixed cover is equipped with the sheath 5 in shoe cream room on eccentric main axis 1, and the centre of gyration of sheath 5 and the centre of gyration of cylinder 4 are same
The heart, when eccentric main axis 1 drive the rotation of sheath 5, reduce the mutual collision and friction between fluid, so as to ensure that the steady of oil temperature
It is fixed；Because rotary speed is not high, its outside centrifugal force is smaller, also ensures that the relatively placidity of lubricating oil, is unlikely to outside
Leakage, but lubricating oil and can infiltrates through inside bearing block and bearing is lubricated；Grease lubrication performance in bearing block is good, also
It can be taken up with stem shaft with gap, prevent oil liquid leakage.
For the linking intensity between guarantee sheath 5 and eccentric main axis 1, in the space between the sheath 5 and eccentric main axis 1
It is filled with epoxy resin 6；In order to reduce the dosage of epoxy resin 6, pvc pipe 7 is inserted with epoxy resin 6.
The technical concepts and features of above-mentioned embodiment only to illustrate the invention, its object is to allow be familiar with technique
Personage can understand present disclosure and be carried out, and it is not intended to limit the scope of the present invention, all according to this hair
The equivalent change or modification that bright Spirit Essence is made, it should all cover within the scope of the present invention.
