Description
Background technique
The present invention relates to technical field of motors, relate in particular to the draining pump technical field of motors.
Background technique
The mandate publication number is CN2916195Y, notice of authorization day is on June 27th, 2007, denomination of invention is the Chinese utility model patent of " a kind of centrifugal draining pump ", a kind of centrifugal draining pump is disclosed, there is the receiving cavity of a ccontaining axle sleeve in its impeller central authorities, and the axle sleeve sidewall is provided with the startup muscle, and the receiving cavity inwall is provided with spacing muscle, come in contact and transmission by a pair of beam between the opposing side of startup muscle and spacing muscle, beam is embedded in respectively in the groove that starts muscle and spacing muscle by fin.When rotating shaft was rotated, the startup muscle on the axle sleeve promptly passed through the beam indirect drive in the spacing muscle of impeller receiving cavity, thereby drives impeller is rotated.In this patent, beam is to be embedded in the spacing muscle of receiving cavity of the startup muscle of axle sleeve and impeller, and therefore, the action of beam is synchronized with axle sleeve or impeller respectively, and damping mainly comes from absorption and the buffering of the elastic material of beam to mechanical impact force.
The mandate publication number is CN201262196Y, notice of authorization day is on June 24th, 2009, denomination of invention discloses a kind of rotor of permagnetic synchronous motor and the transmission device between the working component for the Chinese utility model patent of " rotor of permagnetic synchronous motor and the transmission device between the working component ", the axle sleeve sidewall is provided with first and starts muscle, the receiving cavity inwall of working component (being equivalent to impeller) is provided with spacing muscle, the first startup muscle and spacing muscle are the dislocation design, be provided with the anticollision gap between the two, be provided with a snubber block between the two, snubber block contacts with startup muscle and spacing muscle respectively, thereby the rotation that axle sleeve starts muscle is passed to the spacing muscle of working component, drives working component and rotate.Snubber block neither is fixed in axle sleeve (startup muscle) and also is not fixed in working component (spacing muscle), but independently is arranged in the receiving cavity of working component.When rotor rotation, start muscle and at first contact snubber block, promote elastomer block then and contact spacing muscle, the startup muscle is distributed in being compressed in the volume of snubber block to the impact energy of spacing muscle, start the impact of muscle thereby slow down, and then reduce the operational noise of permagnetic synchronous motor spacing muscle.Contact with the direct of spacing muscle for fear of starting muscle, start muscle and spacing muscle in this patent and be the dislocation design.In order to reach the purpose of dislocation, will inevitably reduce to start the diameter or the length of muscle and spacing muscle, promptly start muscle and spacing muscle attenuation shortens, stress surface diminishes.When the power of pump increased, stress surface little meeting causing member damaged situation appearance such as more.
Summary of the invention

Embodiment
As Fig. 1～shown in Figure 2, be centrifugal draining pump, it comprises two rotor chamber and the draining pump cover chambeies that isolate mutually.Rotor chamber is made up of the pump housing 2, p-m rotor 3, rotor shaft 7, bearing 1,4 and bearing supports; Draining pump cover chamber is made up of the pump cover that contains water intake, axle sleeve 9, impeller 10 and impeller retaining washer 5.The alternating magnetic field that coil 8 produces drives p-m rotor 3 by stator iron core 11 and rotates forward or backwards.
As shown in Figure 8, impeller 10 central authorities have a receiving cavity 12, are used for ccontaining axle sleeve 9, below the receiving cavity of impeller 10 by the impeller retaining washer 5 of annular axle sleeve 9 shutoff in receiving cavity 12.Receiving cavity 12 madial walls protrude a spacing muscle 121.Axle sleeve 9 has a tubular body, and the outer side wall of tubular body outwards protrudes one and starts muscle 91.Start the relation that muscle 91 and spacing muscle 121 are in interference.For this example,, therefore, there are two groups of interference surfaces between the two because startup muscle 91 and spacing muscle 121 respectively have one.
Be installed on two damping elastomers 6 in the receiving cavity 12, be in respectively between two groups of interference surfaces that start muscle and spacing muscle, shown in Fig. 4 a, lay respectively at the both sides that start muscle 91.Radial distance between the radial width of damping elastomer 6 and axle sleeve main body and the receiving cavity main body inner wall is suitable, the specifically difference to some extent according to the elastomeric concrete pattern of damping.Damping elastomer 6 can slide in the receiving cavity main body or roll.The damping elastomer can adopt as Fig. 6～various structural types shown in Figure 7, and can adopt cross section is fan-shaped fan-shaped cylinder 61, cylindrical body 62, oval cylinder 63 or spheroid 64.For fan-shaped cylinder 61, cylindrical body 62 and oval cylinder 63, its cartridges parallel is in the direction of rotor shaft 7 during installation.For damping elastomers such as fan-shaped cylinder 61 and oval cylinders 63, during work in receiving cavity, sliding, for guaranteeing its smooth and easy slip, between damping elastomer and axle sleeve main body and the receiving cavity main body inner wall for concerning movingly; For damping elastomers such as spheroid 64 or cylindrical bodys 62, in receiving cavity, roll during work, can adopt interference fit between damping elastomer and axle sleeve main body and the receiving cavity main body inner wall.
Except adopting the solid construction shown in each figure of Fig. 6, also can adopt hollow- core construction 65,66,67 as shown in Figure 7.The time distortion by compression of the damping elastomer of hollow-core construction is big, has good cushioning effect.
The damping elastomer can adopt plastic material, as rubber.
The main body outer side wall of axle sleeve 9 can adopt the band tooth too and not be with two kinds of structural types of tooth, shown in Fig. 5 a and Fig. 5 b.The axle sleeve outer side wall is provided with the strip tooth and helps promoting the rolling of damping elastomer.
When rotor rotation, the axle sleeve 9 that is fixed on the rotor shaft 7 promotes impeller 10 rotations by damping elastomer 6.Because of elastomer has good cushioning effect, so the beating noise can reduce even eliminate impeller 10 and start the time between axle sleeve 9 and the damping elastomer 6, between damping elastomer 6 and the impeller 10, peace and quiet more feel more comfortable when making machine operation.When motor reverses, because owing to start between another group interference surface of muscle and spacing muscle and also be provided with the damping elastomer, so start muscle and can directly not contact spacing muscle equally and cause noise.
In this example, axle sleeve is provided with one and starts muscle 91, receiving cavity is provided with a spacing muscle 121, in the practical application, do not get rid of the startup muscle that is provided with one or more and the situation of the spacing muscle of one or more, between the every group of interference surface that starts muscle and spacing muscle, all install a damping elastomer, directly do not touch spacing muscle so that start muscle, but rotation is passed to spacing muscle by the damping elastomer.
In this example, between each group interference surface, be provided with a damping elastomer, in the practical application, two even a plurality of damping elastomer can also be set, shown in Fig. 4 b.
The present invention includes but be not limited to the content of the foregoing description, other all fall within protection scope of the present invention with product structure that technological scheme of the present invention has identical essentiality content.
