Abstract
The utility model discloses a vibration source, comprising an anti-vibration motor, which is characterized in that vibration source chambers, main shafts, eccentric blocks, connection cylinders and couplings are arranged respectively at the two sides of the anti-vibration motor. Wherein, the main shafts are connected with the anti-vibration motor through the couplings; the eccentric blocks and the vibration source chambers are arranged on the main shafts; the vibration chambers are connected with the anti-vibration motor through the connection cylinders. As the utility model adopts the above-mentioned structure, the limitation of the size and space of the motor that the main shaft can bear is overcome, thereby the bearing with more bearing capacity can be chosen; the supporting way of the eccentric block is changed from the cantilever type to simple support, the number of the supporting bearings is added, therefore the service life of the bearings is prolonged; the stress status of the motor rotor is improved greatly; the heat source of the motor is dispersed, the working temperature is reduced, and the working condition is improved greatly; the safety of the vibration source is enhanced and the service life of the vibration source is prolonged, and the exciting efficiency is enhanced maximally.
Description
Technical field
The utility model relates to a kind of industrial or agricultural vibratory equipment, especially relates to a kind of vibration source that uses at aspects such as drilling well, mining industry, chemical industry, agriculturals.
Background technology
At present, prior art commonly used both at home and abroad mainly contains: 1, motor drives the mechanical vibration source that centrifugal device is formed by all kinds of machine driving.Existing various mechanical vibration source basic structure principle is: common or fire-proof motor drives by transmission mechanisms such as V belt, synchronous cog belt or various shaft couplings and is supported on two eccentric block or eccentric shafts between the bearing block, thereby produce periodically variable exciting force, form the periodic vibration of different tracks (as circle, straight line, ellipse etc.) again by the various combination of such vibration source on the vibration facility, finally realize required work purpose.2, vibrating motor.Vibrating motor is a kind of novel vibrating source of comparatively fast being developed during the last ten years recently.It is the directly differentiation that twin shaft is stretched motor, and promptly direct setting-up eccentricity piece forms on two shaft extensions of motor.Vibrating motor can be divided into plain edition and long excellent type two classes according to its draw ratio scope.The main distinction of vibrating motor and common electric machine is: the bearing capacity of (1) electric machine casing, block bearing requires higher, and static strength is almost than the high order of magnitude of common electric machine; (2) removed radiator fan and only depended on the housing natural heat dissipation, added that load is heavy, bearing heating is big, so motor body temperature rise ratio common electric machine is much higher, so the insulation temperature resistant grade of vibrating motor stator is higher, reaches 150 ℃ or higher; (3) vibrating motor stator coil, the coil vibration resistance of taking out line, binding post etc. requires harshlyer, must take such as special technological measures such as casting curing agent.The weak point that prior art exists: 1, mechanical vibration source exists: (1) complex structure; (2) poor reliability; (3) noise is big.Deng not enough.2, vibrating motor exists: (1) poor radiation, operating temperature height; (2) lubricated, air-proof condition is poor; (3) bearing life is short; (4) general, plain edition vibrating motor work exciting force application point is far away apart from the desirable load-carrying surface of work housing, thereby is difficult to pass to effectively work housing, and exciting efficiency is lower; (5) grow excellent type vibrating motor then complex structure, anufacturability is poor, difficulty is big, cost is high.
Summary of the invention
The purpose of this utility model just is to provide a kind of rotor force-bearing situation that makes to be greatly improved, and the dispersion of motor thermal source, operating temperature reduce, prolong bearing life, improve the vibration source of exciting efficiency.
The purpose of this utility model can realize by following measure:
The utility model comprises the antivibration motor, be respectively arranged with vibration source chamber, main shaft, eccentric block, connection tube and shaft coupling in antivibration motor both sides, wherein main shaft combines by shaft coupling and antivibration motor, main shaft is provided with eccentric block and vibration source chamber, and the vibration source chamber combines with the antivibration motor by connecting tube.
Be provided with bearing in the utility model in the vibration source chamber, main shaft is placed in this bearing, and eccentric block then is arranged on the main shaft between bearing.Be connected or the bolt connection etc. of cracking for key between eccentric block and the main shaft.Between vibration source chamber and the connection tube is flange or screwed connection.Connect between tube and the antivibration motor and be connected or screwed connection for flange.The mechanism of antivibration motor both sides certainly, also can be asymmetric layout for being symmetrical arranged.
The utility model is because structures such as employing is symmetrical arranged respectively in antivibration motor both sides, vibration source chamber, main shaft, eccentric block, connection tube, shaft couplings.Exciting eccentric block and motor are separated, overcome the restriction that main shaft bears motor size and space, can select the bigger bearing of bearing capacity for use, and the support pattern that has changed eccentric block promptly changes into freely-supported, increased block bearing quantity by cantilever, so bearing life prolongs greatly; The rotor force-bearing situation is greatly improved, and the motor thermal source disperses, operating temperature reduces, and condition of work is improved greatly.These are all finally to playing an important role the reliability and the service life of improving vibration source.The utility model also can adapt to the size of work housing easily by the length dimension that changes main shaft shaft extension and connection tube, improves exciting efficiency to greatest extent.
Description of drawings
Accompanying drawing is a structural representation of the present utility model;
The specific embodiment
The utility model is done with detailed description below in conjunction with drawings and Examples:
As shown in the figure, the utility model comprises antivibration motor 6, be symmetrically arranged with vibration source chamber 1, main shaft 2, eccentric block 3 in antivibration motor 6 both sides respectively, connect tube 4 and shaft coupling 5, wherein main shaft 2 combines by shaft coupling 5 and antivibration motor 6, main shaft 2 is provided with eccentric block 3 and vibration source chamber 1, and vibration source chamber 1 combines with antivibration motor 6 by connecting tube 4.Be symmetrically arranged with two bearings in vibration source chamber 1, main shaft 2 is placed in this bearing, and 3 of eccentric blocks are arranged on the main shaft 2 between two bearings.Be connected for key between eccentric block 3 and the main shaft 2.Vibration source chamber 1 is connected for flange with connecting between the tube 4.Connect between tube 4 and the antivibration motor 6 and be connected for flange.The mechanism of antivibration motor 6 both sides is for being symmetrical arranged.
Operation principle of the present utility model is as follows: the utility model is to the improvement of vibrating motor or distortion, it is separated exciting eccentric block and motor, overcome the restriction that main shaft bears motor size and space, can select the bigger bearing of bearing capacity for use, and the support pattern that has changed eccentric block promptly changes into freely-supported, increased block bearing quantity by cantilever, so bearing life prolongs greatly; The rotor force-bearing situation is greatly improved, and the motor thermal source reduces, operating temperature reduces, and condition of work is improved greatly.These are all finally to playing an important role the reliability and the service life of improving vibration source.In addition, the present invention also can adapt to the size of work housing easily by the length dimension that changes main shaft shaft extension and connection tube, improves exciting efficiency to greatest extent.
