In the process of installing the rotor assembly 6 with the bearing 61 into the base 7, the utility model is firstly placed under a press, the base 7 is positioned on the base positioning seat 1, namely, the lower port of the base 7 is buckled on the base positioning step 11, and the lower port of the base is in clearance fit with the base positioning step 11; the rotor assembly 6 is hung right above the guide sleeve and is positioned at the center of the machine base; the rotor assembly 6 is pressed by the press to move downwards, the rotor assembly 6 is lowered along with the pressure of the press, and the bearing 61 in the rotor assembly 6 slowly enters the bearing hole 71 of the base 7 in the lowering process until the press-fitting is completed. In the process, the machine base positioning seat 1 can limit the position of the machine base 7, the machine base is prevented from moving, the rotor guide sleeve 3 can position the rotor assembly 6 in the descending process, the problem of eccentricity in the descending process of the rotor is avoided, therefore, under the action of the machine base positioning seat 1 and the rotor guide sleeve 3, the accurate assembly of the rotor assembly 6 on the machine base can be realized, the eccentricity problem is avoided, and the assembly between the machine base and the rotor guide sleeve is remarkably facilitated. On the other hand, due to the fact that the assembling position between the two is accurate, the problem of abrasion of the two caused by assembling deviation can be avoided.
The embodiment is further configured as follows: four counter bores 111 are formed in the base positioning step 11, an elastic support component 2 is arranged in each counter bore 111, the upper end of each elastic support component 2 is exposed outside the counter bore 111 in a natural state to support the lower end face of the base, and the elastic support components 2 can move towards the bottoms of the counter bores 111 after being pressed. After the bearings of the rotor assembly 6 are all pressed into the bearing holes 71 of the base, the press continues to apply pressure, and presses the elastic support assembly 2 to move downwards until the elastic support assembly 2 is pressed to the lowest point, namely the upper end surface of the elastic support assembly 2 is flush with the plane of the base positioning step 11, and the press stops pressing. Under the arrangement structure, the prompting function can be realized for operators, the rotor assembly 6 and the base are prompted to be assembled in place, and the assembling accuracy is further improved; and the problem of pressure loss of the rotor assembly 6 and the base due to continuous pressure application is avoided.
The embodiment is further configured as follows: the elastic support assembly 2 comprises a spring 23, a limit bolt 22 and a support sleeve 21; the inner wall of the upper end of the supporting sleeve is provided with a limiting step 211, and the supporting sleeve 21 is sleeved on a limiting bolt 22; the rod body of the limiting bolt 22 penetrates through the supporting sleeve 21 and the bottom wall of the counter bore 111 and is matched with a nut 24, and the head 221 of the limiting bolt 22 is matched with the upper surface of the limiting step 211; the spring is sleeved on the limiting bolt, the lower end of the spring 23 abuts against the bottom wall of the counter bore 111, and the upper end of the spring abuts against the lower surface of the limiting step 211, so that the limiting bolt 22 and the support sleeve 21 are pushed upwards. Under this structure, can realize playing the effect of effective support to the lower terminal surface of frame 7 to and play the effect that elasticity descends after the pressurized, spring 23 can play certain buffering effect promptly, avoids rotor subassembly 6 and frame to take place the problem of pressure loss. It should be noted that the sum of the elasticity of the spring 23 and the friction between the support sleeve 21 and the inner wall of the counterbore 111 is greater than the friction between the bearing 61 in the rotor assembly 6 and the bearing hole 71 in the housing 7, so that after the rotor assembly 6 is pressed by the press, the rotor assembly 6 descends and is pressed into the housing 7.
