Detailed description of the invention
As shown in Figure 2, shell in the present invention is the rectangular structure of a barrel-shaped shape, one end open, the other end is airtight, the present invention uses the main purpose of this housing to be all to be enclosed in the end-cap assembly of whole motor, stator module, rotor assembly in housing, making one entirety of outer formation of whole motor, one of them function is exactly convenient installation.Being provided centrally with a positioning shrinkage pool in the seal face of housing, this shrinkage pool is used to place oil storage seal washer.The internal diameter of shrinkage pool and the external diameter of the support of bearing have strict axiality to require.A part for packing ring highly embeds the support of bearing, and also another part height embeds in the shrinkage pool of shell, and packing ring protrudes the shrinkage pool height equal to shell for the height of the support of bearing.Also have the oil storage tank of two depressions can play the effect storing lubricating oil in the plane of the support of bearing, it is ensured that sufficient lubricating oil storage.
Being provided with step on a section of positioning shrinkage pool on wall in the enclosure, the internal diameter in this step makes shell is divided into different two section so that one section of internal diameter of shell aperture end is more than one section of sealed end；The effect of step is for supporting the position with fixed magnet: the external diameter of magnet is more than one section of sealed end, and magnet can be remained stationary as after being placed into stepped locations and is fixed by glue, it is ensured that the plunger position of rotor combination is positioned at the magnetic field center of magnet.
As it is shown on figure 3, be provided with four convex walls in the case surface of the support of bearing, convex wall is arranged on the same circumference of support of bearing case surface symmetrically；The whole support of bearing is consistent to the diameter of convex wall outer and the shell aperture section internal diameter of motor from center；The external diameter of convex wall and the internal diameter of shell are clearance fit state, it is ensured that the support of bearing and outer casing inner wall fit tightly and meet sufficient release power and require.
Being provided centrally with positioning through hole at the support of bearing, being provided with the groove of annular on the inwall side of through hole, annular groove is concentric with positioning through hole, and is provided with lubricating oil in annular groove；Its function is after the rotary shaft of motor inserts positioning through hole, during rotating, rotary shaft contacts the effect that not only can play lubrication to rotary shaft with lubricating oil, and by the physical characteristic of lubricating oil, the noise producing in rotary shaft rotation process can also be absorbed, the noise that whole motor produces in the course of the work can be reduced.
As shown in Figure 4, the bottom at the support of bearing has the step of two and half arcs protruding, symmetrically state, and its width is equal to the internal height of shell.
In order to meet different vibration sense demand, the length of point copper can adjust, and the base plane height of the support of bearing also can adjust therewith with inner plane height, meets intensity simultaneously and requires and vibration sense requirement.
As shown in Figure 5, when being fitted without motor case, the end-cap assembly of motor, stator assembly and rotor assembly consistent with existing motor configuration, places different in the present invention is that rotary shaft passes through oscillator and fixing with oscillator is connected, rotary shaft is inserted partially on the positioning through hole on the support of bearing through oscillator, rotary shaft is fixed, does not haves lower skew in working order.The diameter of oscillator is substantially less than the diameter of the support of bearing so that oscillator will not be with motor case contact internal walls in rotation process.
As shown in Figure 1, it is the structural representation that whole groups of motors installs after finishing, the motor assembling Fig. 3 is pressed in the shell of Fig. 2, the side of motor case openend is provided with a positioning gap, this gap matches with the locating fastener on end-cap assembly, whole end-cap assembly can be positioned be fixed on the shell of motor, in the enclosure, the support of bearing is supported by the step in shell, the diameter of the oil storage seal washer of the support of bearing other end is greater than the diameter of the positioning through hole of the support of bearing, and oil storage seal washer, positioning through hole, positioning shrinkage pool three is all concentric.The lubricating oil flowing out in annular groove from the support of bearing in rotation process flows to, in positioning shrinkage pool, then be absorbed by oil storage seal washer so that the space in whole motor case does not haves unnecessary lubricating oil, it is ensured that the cleannes in whole space.
Whole motor in the present invention is entirely sealed in motor case, on the end face of end-cap assembly, only remain with power connection end, in motor welding process, directly a side of shell can be welded with circuit board, do not need just can weld as traditional motor adjusts position, same effect, because the present invention is to use totally enclosed shell, solder in welding process can be avoided completely to enter in motor shell, affect the normal work of motor.Same, because using full-closed structure, the noise of generation to be substantially less than open, and can be absorbed noise by lubricating oil.
The present invention has the effect being substantially better than existing structure motor: SMT highly standardized, easy attachment, high reliability and low noise, be a highly competititve significant product.
Under the trend with screen enlarging day by day frivolous at mobile phone; this motor configuration can ensure that in the state of low clearance; meeting bigger vibration sense demand by the size of extension housing and rotor assembly and oscillator, the improvement carrying out on this basis and change, in the protection domain all invented at this.
The invention is not limited in aforesaid detailed description of the invention.The present invention expands to any new feature disclosing in this manual or any new combination, and the arbitrary new method of disclosure or the step of process or any new combination.
