Abstract
This application provides a kind of rotors, the diameter being connected including thin cylinder body end and with the thin cylinder body end is more than the thick cylinder body end of the thin cylinder diameter, the thin shell portion is provided with cruciform vent, and the thick cylinder body end is provided with and the body concentric round hole of the thick cylinder and linear type hole.Production work can be enormously simplified by producing rotor provided herein, improve production efficiency, and the integral strength of rotor and other mechanical performances are significantly improved.
Description
Technical field
This application involves auto parts and components production fields, and in particular to a kind of rotor.
Background technology
Existing auto parts and components rotor, since its shape limits, the mach mode of generally use is produced, in
Hole shape is processed by the way of milling.Since the dimensional tolerance of both ends endoporus, symmetry tolerance are all very stringent, mach difficulty
Degree is very big, and yield rate is relatively low, and milling process long processing time, and efficiency is low, causes total manufacturing cost high.
Invention content
In order to solve the above technical problems, this application provides a kind of rotor, including thin cylinder body end and with it is described thin
The diameter that cylinder body end is connected is more than the thick cylinder body end of the thin cylinder body end diameter, and the thin cylinder body end is provided with ten
Font hole, the thick cylinder body end are provided with the round hole and linear type hole concentric with the thick cylinder body end.
It is also provided with connecting hole between the cruciform vent and the round hole.
The cruciform vent is preferably that the opposite end of the cruciform vent is to extend to the thin cylinder end side surface
Trepanning, in addition both ends are endoporus.
Linear type hole is preferably by the trepanning of the thick cylinder body end dimidiation.
The opening direction in the linear type hole is preferably perpendicular with the opening direction of the cruciform vent.
Rotor provided herein, one end are the internal via shapes of cross shape, and other end is the interior of keyhole shape
Hole.This part is used for high-speed rotating component, and both ends respectively connect an axis, and the effect of this part is exactly to transmit torque.In order to transport
Turn steady, this will this part both ends endoporus must to cannot just, between endoporus and outer circle there is larger concentric deviation, otherwise,
In rotation process, the axis decentraction at both ends can cause larger vibrations, destroy the stability of rotation.
On the basis of technique before summary, new rotor is developed, may be implemented first by the way of cold forging, is produced
Out part blank is machined out again later, produces final fabricated part.
Rotor provided herein, shape is fairly simple, is suitble to cold-forging technique, production efficiency is high, and production cost is low, can
To realize fast and easy, low cost, produce in large quantity.
Rotor provided herein, can produce this blank by using cold-forging technique, and what is finished later is new
Technique is produced.Production work can be enormously simplified by producing rotor provided herein, improve production efficiency.On an equal basis
Under the conditions of, daily yield be before 2.2 times of technique；And the consumption of raw material is reduced, add with needing to meet pure machine before
The rotor component of work technique is compared, and the utilization rate of material has been increased to 83% from 45%, reduces metal fragment, cutting fluid etc.
The generation of solid-liquid waste, is conducive to environmental protection, and the integral strength of rotor and other mechanical performances have and obviously carry
It is high.
Description of the drawings
Fig. 1 is rotor structure schematic diagram provided herein.
Specific implementation mode
The application is further detailed below in conjunction with attached drawing.
Rotor as shown in Figure 1, including thin cylinder body end 1 and the diameter that is connected with thin cylinder body end 1 are more than thin circle
The thick cylinder body end 2 of 1 diameter of cylinder end, thin cylinder body end are provided with cruciform vent 3, and thick cylinder body end 2 is provided with and thick cylinder
The concentric round hole 4 of body section 2 and linear type hole 5, are additionally provided with connecting hole 6, cross between cruciform vent 3 and round hole 4
The opposite end in hole 3 is the trepanning for extending to thin 1 side of cylinder body end, and in addition both ends are endoporus, and linear type hole 5 is by thick cylinder
Hold 2 dimidiations, the opening direction and the opening direction of cruciform vent 3 in linear type hole 5 perpendicular.
The rotor of present embodiment is suitble to cold-forging technique, and Sizes since its is relatively simple for structure, is next
The allowance that step machining retains is suitable, and fast and easy, low cost may be implemented, produce in large quantity.
