Two fan-shaped impellers are symmetrically arranged on the weighting block of the vibration exciter; and heat is uniformly dissipated when the machine operates normally, so that the service life of the vibration exciter is prolonged; and the fan-shaped impellers are arranged on the weighting block, redundant space of the weighting block is utilized, the weighting block and the fan-shaped impellers are symmetrically arranged, the fan-shaped impellers are in inner and outer ring plate structures and are fixed with the weighting block respectively, so that the structure is stable, the occupied space is small, and the aim of temperature reduction of the vibration exciter is effectively fulfilled.
Description
Technical field
The utility model belongs to Machine Design and makes the field, especially belongs to mining machinery and manufactures and designs the field, particularly design of a kind of cooling fan structure of vibrator and manufacturing.
Background technology
Usually use vibrating device in the mining machinery, its generation of vibration is accomplished by vibrator and is realized.Adopt piece off-centre as exciting force, exciting force is strong.Sifting bed produces the vibration of round track under the effect of vibrator; Make material bed loose on the screen cloth and leave screen cloth and throw, make fine fraction can see through the bed of material and fall, discharge through sieve aperture; And the particle that will be stuck in the sieve aperture shakes; Particulate moves to the bottom, thereby discharges the effect that reaches the generation screening through sieve aperture, and the departments such as stone pit, mine, building materials, electric power, colliery and chemical industry that are widely used in carry out the screening plant that stock grading is used.
Present domestic vibratory sieve vibrator adopts two kinds of grease lubrication or oil lubrications more.There is following problem in grease lubrication: 1. all need grease-added every day; 2. lubricating grease is added vibrator inner bearing temperature is raise, and adds that I haven't seen you for ages increases bearing friction increasing and noise, reduces problems such as bearing service life; There is the too high problem of temperature rise equally in the oil lubricating type vibrator, particularly under heavy load, moves.So whatsoever lubricating system all solves the too high problem of vibrator temperature rise.
Summary of the invention
The utility model discloses a kind of cooling fan structure of vibrator according to the deficiency of prior art.The problem that the utility model will solve provides that a kind of effectively to control the vibrator temperature rise too high, prolongs vibrator whole service life cooling fan structure.
The utility model is realized through following technical scheme:
The cooling fan structure of vibrator comprises the weighting block that is installed on the vibrator main shaft, it is characterized in that: the relative another side of gravity block at weighting block has fan-shaped impeller.
Said fan-shaped impeller comprises semicircle outer girth sheets and interior girth sheets, between outer girth sheets and the interior girth sheets fan blade that is obliquely installed is installed evenly, and outer girth sheets is connected fixing through the fixed head at two ends with weighting block.
Said fan-shaped impeller also is connected fixing with weighting block through interior girth sheets.
The weighting block of two symmetries is installed through the fastening bolt group on the further said vibrator main shaft, is separately installed with one group of fan-shaped impeller on two weighting blocks.
The cooling fan structure of above-mentioned vibrator comprises a vibrator, two weighting blocks and two groups of fan-shaped impellers.One group of fan-shaped impeller respectively is installed on two weighting blocks, and is connected through the fastening bolt group.Two weighting blocks are installed on the vibrator main shaft through the key symmetry.The rotation weighting block comprises with rotating shaft and is fixedly coupled bore portion; Vibration when gravity block is arranged at the round part position of integral body with the formation rotation; Another part relative with gravity block on weighting block generally is in vacant state; The utility model utilizes this rest position that fan-shaped impeller is set, and when vibrator was worked, fan-shaped impeller produced cooling blast in company with rotation and played cooling, cooling effect to vibrator preferably when weighting block rotates.
The helpfulness of the utility model, symmetry is installed two fan-shaped impellers on the vibrator weighting block, and machine reaches heat radiation evenly when running well; Thereby increase vibrator service life, the utility model is installed in fan-shaped impeller on the weighting block, utilizes the redundant space of weighting block; And with weighting block and the installation of fan-shaped impeller symmetry; Fan-shaped impeller adopts inside and outside girth sheets structure and fixing with weighting block respectively, Stability Analysis of Structures, takes up room for a short time, has realized the cooling purpose to vibrator effectively.
