The supporting and connecting structure for the iron core and the spindle of the electromagnetic clutch comprises a clutch spindle and the iron core, wherein the iron core is connected to the spindle through a slide bearing made of a copper-based powder metallurgy material or a ferrum-based powder metallurgy material, the inner wall of the slide bearing is in sliding fit with the outer wall of the spindle, the outer wall of the slide bearing is fixedly connected with the inner wall of the iron core.
Description
Technical field
The utility model relates to a kind of magnetic clutch, particularly relates to the support and connection structure of iron core and axle in magnetic clutch.
Background technique
Magnetic clutch comes the Engage and disengage of solenoidoperated cluthes by the power on/off of iron-core coil, in prior art, iron core is connected on main shaft by roller bearings, when iron core is switched on, it is easily damaged that the axis of rolling at iron core place bears the impact of core field, although now antimagnetic rolling bearing occurred, because price is more expensive, operating cost increased.
The model utility content
The technical problems to be solved in the utility model is to provide a kind of novel iron core and the support and connection structure of axle, and its cost is low, long service life, stable working, reliable, noiseless.
The support and connection structure of the utility model magnetic clutch iron core and axle, comprise clutch spindle and iron core, described iron core is connected on main shaft by the sliding bearing of being made by copper based powder metallurgy material or iron-base powder metallurgy material, inwall and the spindle outer wall of described sliding bearing are slidably matched, and the outer wall of sliding bearing is fixedly connected with the inwall of described iron core.
The support and connection structure of the utility model magnetic clutch iron core and axle, wherein also comprise sliding shaft sleeve, the structure of described sliding shaft sleeve, position relationship have two kinds: a kind of, the inwall of described sliding shaft sleeve is fixedly connected with spindle outer wall, the outer wall of sliding shaft sleeve and iron core inwall are slidably matched, one side end face of sliding shaft sleeve is resisted against on a side end face of sliding bearing, and the face area of described sliding shaft sleeve is greater than the face area of sliding bearing; Another kind of, the inwall of described sliding shaft sleeve is fixedly connected with spindle outer wall, the outer wall of sliding shaft sleeve is provided with the groove that a circle is suitable for holding described sliding bearing, the inwall of the inwall of described sliding bearing and end face and described groove is slidably matched, and described sliding shaft sleeve is abutted together by centrosymmetric the first sliding shaft sleeve and second sliding shaft sleeve two-part and forms.
The support and connection structure of the utility model magnetic clutch iron core and axle, the outer wall of wherein said sliding bearing and iron core inwall are by interference fit, welding or cementing being fixed together.
The support and connection structure of the utility model magnetic clutch iron core and axle, the inwall of wherein said sliding shaft sleeve and spindle outer wall are by interference fit, welding or cementing being fixed together.
The support and connection structure difference from prior art of the utility model magnetic clutch iron core and axle is that the support and connection structure of the utility model magnetic clutch iron core and axle adopts the sliding bearing of being made by copper based powder metallurgy material or iron-base powder metallurgy material to substitute the rolling bearing at the place of iron core in prior art, copper based powder metallurgy material, iron-base powder metallurgy material are non-magnet_conductible material, make this sliding bearing not affected by magnetic force, long service life, and cost is cheap than rolling bearing, stable working, reliable, noiseless.
In the support and connection structure of the utility model magnetic clutch iron core and axle, set up the sliding shaft sleeve of two kinds of different structures, both can play the auxiliary positioning effect to sliding bearing, can increase the area that is slidably matched simultaneously, improve the working life of sliding bearing.
Be described further below in conjunction with the support and connection structure of accompanying drawing to magnetic clutch iron core of the present utility model and axle.
Description of drawings
Fig. 1 is the sectional view of the utility model mode of execution one;
Fig. 2 is the sectional view of the utility model mode of execution two.
Embodiment one:
As shown in Figure 1, the support and connection structure of present embodiment magnetic clutch iron core and axle comprises clutch spindle 11, iron core 12, sliding bearing 13 and sliding shaft sleeve 14, sliding bearing 13 is made by copper based powder metallurgy material or iron-base powder metallurgy material, iron core 12 is connected on main shaft 11 by sliding bearing 13, the inwall of sliding bearing 13 and main shaft 11 outer walls are slidably matched, and the inwall of the outer wall of sliding bearing 13 and iron core 12 is fixed together by interference fit.
The inwall of sliding shaft sleeve 14 and main shaft 11 outer walls are fixed together by interference fit, the outer wall of sliding shaft sleeve 14 and iron core 12 inwalls are slidably matched, one side end face of sliding shaft sleeve 14 is resisted against on a side end face of sliding bearing 13, and the face area of sliding shaft sleeve 14 is greater than the face area of sliding bearing 13.
Embodiment two:
As shown in Figure 2, the support and connection structure of present embodiment magnetic clutch iron core and axle comprises clutch spindle 21, iron core 22, sliding bearing 23 and sliding bearing 24, sliding bearing 23 is made by copper based powder metallurgy material or iron-base powder metallurgy material, and the inwall of the outer wall of sliding bearing 23 and iron core 22 is fixedly connected by welding together.
The inwall of sliding shaft sleeve 24 and main shaft 21 outer walls are fixedly connected by welding together, the outer wall of sliding shaft sleeve 24 is provided with the groove 25 that a circle is suitable for holding sliding bearing 23, the inwall of the inwall of sliding bearing 23 and end face and groove 25 is slidably matched, and sliding shaft sleeve 24 is abutted together by centrosymmetric the first sliding shaft sleeve 26 and second sliding shaft sleeve two-part and forms.
Above-described embodiment is described preferred implementation of the present utility model, be not that scope of the present utility model is limited, for example, the outer wall of sliding bearing is not limited in by modes such as interference fit, welding with spindle outer wall with the inwall of iron core inwall, sliding shaft sleeve and is fixedly connected with, and also can fix by other modes of the prior art such as cementing.Under the prerequisite that does not break away from the utility model design spirit, various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of the utility model claims.
