Abstract
The utility model discloses a vibrating elastic vibration exciter, and comprising a motor; the left and the right part of a motor shaft are an exciting vibration box body and an eccentric block; the vibrating elastic vibration exciter is characterized in that the left and the right ends of the motor shaft are connected with an elastic shaft coupling, the lower side of the vibrating vibration exciter is fixed with the matched device through a base, and flexible vibration damping devices are arranged on the bottom part of the motor in parallel. Because the vibration damping devices are added on both ends and the bottom part of the motor, when the eccentric block is rotated at high speed, and the exciting vibration force can be conveyed to the elastic shaft coupling through the vibration box body for decomposing the exciting vibration force; as a result, the service life of the motor can be continuously operated more than three years, and the cost of the motor can be reduced.
Description
The utility model relates to a kind of vibration elasticity vibrator, the supporting elasticity vibrator that is applicable to vibratory sieve, sorting, feed.
Existing vibration vibrator, it comprises motor, motor shaft, eccentric block etc., motor shaft drives heavier eccentric block and rotates at a high speed, because motor load is too heavy, the motor that generally turns round about 3000 hours is just fragile.
The utility model proposes a kind of prolongation electrical machinery life at above-mentioned shortcoming, reduces use cost, vibration elasticity vibrator simple in structure.
Task of the present utility model is finished like this, it comprises motor, about motor shaft exciting casing and eccentric block, it is characterized in that: be connected with yielding coupling on the end about motor reel, be fixed on the supporting equipment by base below the vibration vibrator, flexible vibration absorber is equipped with in the bottom that is parallel to motor, is surrounded with rubber or braided metal band on the yielding coupling and uses platen fastening.
The utlity model has following effect: owing to set up yielding coupling at the two ends of motor, avoided direct vibration, prolonged the service life of motor, lowered cost motor, owing to be added with protective cover in the yielding coupling outside, so reduced noise.
Fig. 1 is a structural representation of the present utility model.
Describe embodiment in detail in conjunction with above accompanying drawing, be connected with eccentric block 2 eccentric blocks 2 on the yielding coupling 4 and be contained in 3 li of exciting casings, yielding coupling 4 is connected with motor 5 usefulness axle, be surrounded with rubber 8 on the yielding coupling 4, protective cover 6 is arranged outward, as exciting force when big, on yielding coupling 4, hold the braided metal band, rubber 8 and braided metal band are fastened on the yielding coupling 4 with platen and screw, be fixed on the supporting equipment by base 1 below the vibration vibrator, lower parallel on motor 5 is equipped with vibration isolation rubber 7, during motor 5 vibrations, owing to increased vibration absorber, avoided direct vibration, increased yielding coupling 4 on the end about motor 5, so when eccentric block 2 rotates at a high speed motor 5, exciting force passes to yielding coupling 4 through exciting casing 3, by 8 slow the shaking of the rubber on the yielding coupling 4 exciting force is decomposed.So the motor life-span can reach running continuously more than 3 years.Reduced the cost of motor.
