Abstract
The utility model relates to a rotor and expansion sleeve connecting device for a centrifuger, comprising a conic drive spindle, an elastic expansion sleeve, a rotor, screws and a cushion ring. The screws and the cushion ring are arranged on the top part in the elastic expansion sleeve. The elastic expansion sleeve is arranged between the conic drive spindle and the rotor. The elastic expansion sleeve matches the conical surface of the conic drive spindle. The screws in the elastic expansion sleeve can make the elastic expansion sleeve move up and down through the screw connection in the conic drive spindle. The utility model has the advantages that the operation safety of the centrifuger is improved, and the trouble of dismounting the rotor is diminished.
Description
Technical field
The utility model relates to a kind of rotor ringfeder connection set that is used for centrifuge, can be used on the centrifugal machine, belongs to the centrifuge technical field.
Background technique
Centrifuge of the prior art does not possess rotor ringfeder connection set, adopt and directly be connected with live axle, the rotor acceleration, deceleration are frequent when centrifuge is worked, vibration is big, and chamber temp is low, and temperature of rotor changes greatly, it is loosening that rotor and live axle are occurred, thereby the generation peril, and more be difficult for making during exchanging rotor rotor to break away from live axle, increased the trouble of dismounting rotor.
Summary of the invention
The purpose of this utility model is to provide a kind of user's of making quick mounting, changes centrifuge rotor, makes rotor be connected the more reliable rotor ringfeder connection set that is used for centrifuge with live axle.
For realizing above purpose, the technical solution of the utility model provides a kind of rotor ringfeder connection set that is used for centrifuge, it is characterized in that, form by taper live axle, elastic expansion-sleeve, rotor, screw and packing ring, screw and packing ring place the top in the elastic expansion-sleeve, and elastic expansion-sleeve places between taper live axle and the rotor, elastic expansion-sleeve and taper live axle cone match, by being threaded in the taper live axle, the screw in the elastic expansion-sleeve can make elastic expansion-sleeve move up and down.
The utility model has adopted an elastic expansion-sleeve between taper live axle and rotor, in the taper live axle screw thread is arranged, the screw that is installed in the elastic expansion-sleeve moves down elastic expansion-sleeve by threaded together, elastic expansion-sleeve links together rotor, elastic expansion-sleeve and the taper live axle of centrifuge because of stressed radially spreading tightly; Screw in unclamping elastic expansion-sleeve, screw moves up with elastic expansion-sleeve, and elastic expansion-sleeve resiles, and breaks away from rotor.Frequent in the centrifuge rotor acceleration, deceleration, vibration is big, and chamber temp is low, and under the temperature of rotor variation situation greatly, it is loosening to be not easy to make rotor and live axle to occur, thereby guarantees centrifuge safety, smooth operation under fast state.
The utility model has the advantages that the running Security that improves centrifuge, reduce the trouble of dismounting rotor.
Description of drawings
Fig. 1 is the rotor ringfeder connection set structural representation that is used for centrifuge;
Fig. 2 is for being furnished with the structural representation of even opening around the spring ringfeder.
Embodiment
The utility model will be further described below in conjunction with drawings and Examples.
Embodiment
As shown in Figure 1, for being used for the rotor ringfeder connection set structural representation of centrifuge, by taper live axle 1, spring ringfeder 2, rotor 3, screw 4 and packing ring 5 are formed, spring ringfeder 2 is installed between taper live axle 1 and the rotor 3, elastic expansion-sleeve 2 and taper live axle 1 cone match, by being threaded in the taper live axle 1, screw 4 and packing ring 5 are installed on the top in the spring ringfeder 2, taper live axle 1 is built-in with screw thread, screw 4 moves downward spring ringfeder 2 by the screw thread on the taper live axle 1, owing to be furnished with even opening 6 around the spring ringfeder 2, as shown in Figure 2, the 2 stressed generation radial expansions of spring ringfeder, thereby make taper live axle 1, spring ringfeder 2 and rotor 3 linking together tightly, when unclamping screw 4, by the boss on the screw 4 with spring ringfeder 2 jack-up upwards together, spring ringfeder 2 radial contraction are resiled, and rotor 3 just unclamps with spring ringfeder 2 at once.
During work, tighten screw 4, the 2 stressed generation radial expansions of spring ringfeder, auto lock taper live axle 1 and rotor 3.Use this ringfeder Placement, rotor and live axle are not easy to occur loosening, and it is more reliable and secure to make that rotor connects, thereby improve the Security of whole system operation, significantly reduce the trouble that the user dismantles rotor simultaneously.
Claims (2)
