Abstract
The utility model belongs to the technical field of mechanical equipment and provides a driving shaft and rotary impeller assembly structure in a water pump. The driving shaft and rotary impeller assembly structure comprises a rotary impeller and a driving shaft, wherein the rotary impeller is internally provided with a mounting hole matched with the driving shaft, and balls are arranged between the driving shaft and the top of the mounting hole; and when the rotary impeller rotates, the balls rotate along with the rotary impeller when the rotary impeller rotates, and the rotating speed of the balls is lower than that of the rotary impeller. The driving shaft and rotary impeller assembly structure disclosed by the utility model has the advantages of reducing the friction between the driving shaft and the mounting hole of the rotary impeller and further prolonging the service life of the water pump.
Description
Technical field
The utility model belongs to mechanical equipment technical field, relates to live axle and wheel rotor assembly structure in a kind of water pump.
Background technique
Wheel rotor and live axle all are to be employed in to offer the mounting hole that adapts with live axle on the wheel rotor in the existing water pump structure; The length of the mounting hole that live axle can stretch into is greater than the degree of depth of mounting hole; Make wheel rotor be limited by live axle to the axial displacement of pump seat; The shortcoming of this live axle and wheel rotor assembly structure is: working life is short; Reason is because the magnetic force of active magnet ring in the wheel rotor, and wheel rotor is attracted to the pump seat direction and makes to contact and produce between mounting hole and the live axle top on the wheel rotor and rub and wear and tear, thereby has influenced the normal use of water pump.
Summary of the invention
The utility model technical problem to be solved is the present situation to existing technology, and provides a kind of simple in structure, and frictional force is few, live axle in the water pump of long service life and wheel rotor assembly structure.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: live axle in a kind of water pump and wheel rotor assembly structure; Comprise wheel rotor and live axle; Offer the mounting hole that matches with live axle in the described wheel rotor; Between the top of live axle and mounting hole, be provided with ball, when described wheel rotor rotates ball rotate with wheel rotor and its rotating speed less than the rotating speed of wheel rotor.
The measure of taking for the optimization such scheme specifically comprises:
In the live axle and wheel rotor assembly structure in above-mentioned a kind of water pump, be provided with first pad and second pad between described ball and the live axle.Here guarantee the stability of rotating on the one hand through first pad and second pad, reduced the frictional force that produces when rotating on the other hand, prolonged the working life of water pump.
In the live axle and wheel rotor assembly structure in above-mentioned a kind of water pump, the plane that described mounting hole contacts with ball is tapered, is filled with lubricant oil in the gap between ball, mounting hole and live axle three.Here through the lubricant oil power of further reducing friction.
Compared with prior art; The advantage of the utility model is through between live axle and wheel rotor mounting hole, first pad, second pad and ball being set; Reduce the frictional force between live axle and the wheel rotor mounting hole, therefore prolonged the working life of water pump.
Description of drawings
Fig. 1 is live axle and the wheel rotor external structure schematic representation in this water pump;
Fig. 2 is the internal structure schematic representation of live axle and the wheel rotor assembling in this water pump.
Among the figure, wheel rotor 1; Live axle 2; Mounting hole 3; Ball 4; Gap 5; Driven magnet ring 6; Active magnet ring 7; First pad 8; Second pad 9.
Embodiment
Below be the specific embodiment of the utility model and combine accompanying drawing, the technological scheme of the utility model is done further to describe, but the utility model is not limited to these embodiments.
As depicted in figs. 1 and 2; Live axle in a kind of water pump and wheel rotor assembly structure comprise wheel rotor 1 and live axle 2, offer the mounting hole 3 that matches with live axle 2 in the wheel rotor 1; Driven magnet ring 6 is installed in wheel rotor 1, initiatively magnet ring 7 is installed outside live axle 2.
For the power of reducing friction, between the top of live axle 2 and mounting hole 3, be provided with ball 4, mounting hole 3 is tapered with the plane that ball 4 contacts, and is filled with lubricant oil in the gap 5 between ball 4, mounting hole 3 and live axle 2 threes; Live axle 2 rotates for ease in addition; Be provided with first pad 8 and second pad 9 between ball 4 and the live axle 2; When wheel rotor 1 rotates ball 4 rotate with wheel rotor 1 and its rotating speed less than the rotating speed of wheel rotor 1; So just make the absolute rotating speed of mounting hole 3 and live axle 2 just be decomposed into relative rotation speed and the relative rotation speed between first pad 8, second pad 9 and the live axle 2 between mounting hole 3 and the ball 4; And therefore both relative rotation speeds have just reduced frictional force all less than absolute rotating speed.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the spiritual defined scope of the utility model.
