Abstract

The invention discloses a commutator turning support, and relates to the technical field of fan manufacturing and machining. The commutator turning support comprises a support body, a first bearing and a second bearing are arranged inside the support body, an arc-shaped groove is formed in the support body, and the outer edge of the first bearing and the outer edge of the second bearing extend out from the inner wall of the arc-shaped groove to form a rolling supporting portion. According to the commutator turning support, a bearing rolling bearing mode is adopted in the bearing point of a main shaft, driving force for machining is lowered, meanwhile, a pressure blowing mode is adopted, lubricating and cooling functions are effectively realized on relative movement of the bearings and the main shaft, and meanwhile a chip discharging function is achieved as well.

Description

Commutator turning support
Technical field
The present invention relates to blower fan and manufacture processing technique field, particularly a kind of commutator turning support.
Background technology
Rotor assembly, before dynamic balancing and assembling, needs through twice commutator turning process, with the roughness that guarantees commutator and the contact-making surface of carbon brush and with the concentricity of main shaft, so to take the cylindrical of main shaft during turning be to locate and supporting-point.In prior art, the main shaft orientation supporting-point adopts V-arrangement surface bearing (as shown in Figure 1), during rotation in the CONTACT WITH FRICTION mode; The material of V-arrangement bearing-surface 100 is to adopt jewel or carbide alloy to insert, and rotating speed during processing commutator 3 is between 1500-3000n/min, add the man-hour driving pressure larger, need to carry out oil injecting lubricating to V-arrangement bearing-surface 100, and frictional heat produces oil vapour pollution, affected the performance of commutator 3; Frictional heat, make main shaft 30 contact surface coating softening simultaneously, forms trace wearing and tearing and skin effect phenomenon, and on the motor that uses oil-bearing structure, wearing and tearing and skin effect phenomenon directly have influence on assembly precision and the service life of motor.
Summary of the invention
(1) technical problem that will solve
The technical problem to be solved in the present invention is how to reduce turning and add the frictional force of turning in man-hour support to bearing, thereby reduce the driving force of processing.
(2) technical scheme
In order to address the above problem, the invention provides a kind of commutator turning support, described turning support comprises: be provided with clutch shaft bearing, the second bearing in rack body, described rack body, described rack body is provided with deep-slotted chip breaker, the outer rim of described clutch shaft bearing, the second bearing is stretched out described deep-slotted chip breaker inwall, forms rolling support sector.
Wherein, described clutch shaft bearing, the second bearing place axis are vertical with described rack body.
Wherein, the arc of described deep-slotted chip breaker to the number of degrees of central angle, be 180 degree.
Further, described rack body inside is provided with the air flue communicated with the external world, and described air flue comprises gas outlet, air inlet, and described deep-slotted chip breaker place is located in described gas outlet, and described air inlet is located at described rack body outside.
Further, described commutator turning support also comprises pressure suppling device admittedly, and the air feed end of described pressure suppling device is communicated with the air inlet of described air flue.
(3) beneficial effect
Turning support of the present invention, main shaft supporting point has adopted the bearing element support pattern, has reduced the driving force of processing, adopts the pressure blowing method simultaneously, relative motion to bearing and main shaft has effectively realized lubricated and cooling function, has again chip removal function simultaneously concurrently.
The accompanying drawing explanation
Fig. 1 is the structural representation of commutator turning support in prior art;
Fig. 2 is the structural representation of a kind of embodiment of commutator turning support of the present invention;
Fig. 3 is the internal cross section figure of commutator turning support in Fig. 2;
Fig. 4 is schematic diagram when in Fig. 2, commutator turning support arranges commutator and main shaft thereof.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used for the present invention is described, but are not used for limiting the scope of the invention.
Shown in Fig. 1~4, described turning support comprises: be provided with clutch shaft bearing 11, the second bearing 12 in rack body 1, described rack body 1, described rack body 1 is provided with deep-slotted chip breaker 10, the outer rim (110 of described clutch shaft bearing 11, the second bearing 12,120) stretch out described deep-slotted chip breaker 10 inwalls, form rolling support sector.Main shaft supporting point has adopted the bearing element support pattern, has reduced the driving force of processing.
Preferably, described clutch shaft bearing 11, the second bearing 12 place axis are vertical with described rack body 1.
Preferably, the arc of described deep-slotted chip breaker 10 to the number of degrees of central angle, be 180 degree.
Preferably, described rack body 1 inside is provided with the air flue 13 communicated with the external world, and described air flue 13 comprises gas outlet 130, air inlet 131, and described deep-slotted chip breaker 10 places are located in described gas outlet 130, and described air inlet 131 is located at described rack body 1 outside.Preferably, described commutator turning support also comprises pressure suppling device 2, and the air feed end of described pressure suppling device 2 is communicated with the air inlet 131 of described air flue.Adopt the pressure blowing method, the relative motion of bearing and main shaft 30 has effectively been realized to lubricated and cooling function, have again chip removal function concurrently, got rid of pollution and surperficial abrasion condition simultaneously.
Above embodiment is only for illustrating the present invention; and be not limitation of the present invention; the those of ordinary skill in relevant technologies field; without departing from the spirit and scope of the present invention; can also make a variety of changes and modification; therefore all technical schemes that are equal to also belong to category of the present invention, and scope of patent protection of the present invention should be defined by the claims.
