Abstract
The invention discloses a double-limit shaft and a motor. One end of the shaft comprises at least one planar portion which is in parallel with an axis of the shaft and indents towards the axis of the shaft, and the planar portion is provided with a positioning groove. The double-limit shaft employs the D-type shaft to increase the contact area, a limit retainer ring and the positioning groove are further added for dual positioning, and thereby excellent limit fixing between the motor shaft and connection members is guaranteed.
Description
Technical field
The present invention relates to technical field of motors, particularly relate to a kind of double limitation arbor and motor.
Background technology
Existing motor is undertaken continuing to rotate by electromagnetic conversion, and drives driven member to carry out synchronous rotary by arbor.Such as, the rotation of fan is exactly driven by electric motor to carry out High Rotation Speed, and then realizing the effect of air-supply cooling, the motor shaft of fan is conventional round, and the attachment screw contact-making surface on round flat axle and driven member is point cantact, contact-making surface is less, not easily locate when carrying out screw and fixing, when motor runs up, the easy slippage of screw, cause motor produces noise and hydraulic performance decline, even cause air-conditioning normally to run.
Summary of the invention
The object of the invention is to, a kind of double limitation arbor and motor are provided, detent and spacing back-up ring can be utilized to carry out double limitation and fix, ensure the stable operation of motor.
The present invention realizes the technical scheme that above-mentioned purpose adopts:
According to an aspect of the present invention, provide a kind of double limitation arbor, one end of arbor comprise at least one be parallel to arbor axis and indent to the planar portions of arbor axis, planar portions is provided with detent.
Detent be parallel to planar portions and indent to the axis of arbor; Detent is the groove extended along planar portions width; The structure of detent and planar portions intersection is chamfering; The concave surface of detent and planar portions are positioned at the same side of arbor axis; Planar portions is spaced apart two parts by detent.
According to a further aspect in the invention, provide a kind of motor, the body of motor is equiped with double limitation arbor, stretch out the body of motor outside one end that arbor is provided with planar portions, on arbor, contiguous body place is provided with spacing back-up ring.
The sponson of arbor comprises near the circular shaft section of body and the D profile shaft section at planar portions place, and described spacing back-up ring is located at D profile shaft section and circular shaft section intersection; Spacing back-up ring and arbor are coaxially arranged.
The beneficial effect that the present invention adopts technique scheme to have is:
Motor shaft is changed to D profile shaft and increases spacing back-up ring and detent by the present invention, can ensure that motor contacts with fan well, the contact of D profile is changed to from the point cantact of original round axle, increase contact-making surface, and add dual spacing up and down on original Motor Foundation, reduce the impacts such as complete machine noise because Rig up error causes and hydraulic performance decline, ensure complete machine safe and stable operation.
Accompanying drawing explanation
Fig. 1 is the front view of double limitation arbor of the present invention;
Fig. 2 is the left view of double limitation arbor of the present invention.
Wherein, 1, body; 2, arbor; 3, D profile shaft section; 4, circular shaft section; 5, planar portions; 6, detent; 7, spacing back-up ring.
Embodiment
For the scheme in the present invention is clearly described, provides preferred embodiment below and be described with reference to the accompanying drawings.The following description is only exemplary and be not to limit application of the present disclosure or purposes in essence.Should be understood that, in whole accompanying drawings, corresponding Reference numeral represents identical or corresponding parts and feature.
The present invention is described for common fan, and conventional fan rotates with driven by motor, and motor is generally to be driven with the trip bolt of fan rotating parts by arbor to be connected, thus realizes the synchronous axial system of arbor and rotating parts.But existing arbor mostly is circular shaft, due to the restriction of itself and trip bolt fit system, both are made mostly to be the mode of point cantact, contact-making surface is less, trip bolt is also not easily located, and easily in rotation process, produces the problems such as disengaging of sliding, affects the normal work of fan; Therefore, also have in prior art and change circular shaft into D profile shaft and coordinate with trip bolt, although add contact area, but still there is the problems such as location is inaccurate.
Therefore, in order to more be convenient to coordinating of arbor and the related fittings such as screw, the invention provides a kind of double limitation arbor, one end of arbor 2 comprise at least one be parallel to arbor 2 axis and indent to the planar portions 5 of arbor 2 axis, planar portions 5 is provided with detent 6.Embodiment shown in Fig. 1 and Fig. 2 of the present invention offers detent 6 in the planar portions 5 of D profile shaft 3, but groove design of the present invention is not limited to D profile shaft, applicable equally on the power transmission shaft that other need increase contact area, thus effective positioning action can be played to the connector coordinated with arbor 2.
Detent as follows with the locations of structures relation of miscellaneous part: the parallel and indent of detent 6 is to described planar portions 5, and detent 6 and planar portions 5 intersection seamlessly transit, and can find out from the left view of Fig. 2, stepped between detent 6 and planar portions 5; Detent 6 and planar portions 5 intersection make chamfered, avoid the frictional dissipation that right-angle structure and connector produce, can seamlessly transit when mounted; The concave surface of detent 6 and planar portions 5 are positioned at the same side of arbor 2 axis, and this is the self-strength in order to ensure axle, and therefore detent 6 should not be excessively dark.The end of offering position and arbor 2 of detent 6 in planar portions 5 keeps a determining deviation, thus planar portions 5 is divided into two parts, what it was concrete offer, and position is selected according to the fixed position of arbor 2 with connector, in arbor processing process, just can choose difference as required offer position and process, it is convenient to change, and is applicable to producing in enormous quantities.
Present invention also offers a kind of motor being provided with this kind of arbor, in order to realize the technique effect of double limitation, also on arbor 2, be provided with spacing back-up ring 7, this spacing back-up ring 7 is for the ease of installing, also be provided with breach, the horizontal position at the planar portions place on breach corresponding D profile shaft end 3, in some optional embodiments, this breach is fan shape; This spacing back-up ring 7 is as follows with the locations of structures relation of miscellaneous part: the sponson of arbor 2 also comprises the circular shaft section 4 near body 1, circular shaft section 4 extends in body 1 and is structure as a whole with D profile shaft section 3, and spacing back-up ring 7 is just sheathed on D profile shaft section 3 and circular shaft section 4 intersection; Spacing back-up ring 7 is coaxially arranged with arbor 2, to ensure the stability in arbor 2 rotation process.
In sum, above said content is only embodiments of the invention, only for illustration of principle of the present invention, is not intended to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
