Abstract
The utility model discloses a kind of centrifuge horizontal rotor, the rotor block and hanging pin being integrated including casting, the rotor block includes being symmetrically arranged on the hanging head positioned at middle installation basal disc, some ribs for being located at basal disc periphery, the fork-shaped hanging head for being located at rib outer end, the hanging pin.The utility model can use hot investment casting one-shot forming, the weight saving of rotor block, reduce the load of centrifuge motor at work, extend the service life of motor.Due to hot investment casting one-shot forming can be used, ensure that hanging pin relative to center precision while, rotor block without processing, both save material, shorten the process-cycle again, without man-made assembly hang cut, save cost.
Description
Technical field
The utility model belongs to laboratory centrifuge, and in particular to a kind of centrifuge horizontal rotor.
Background technology
As the important component of centrifuge, horizontal rotor produces powerful centrifugal force by high speed rotation, to sample
Carry out the separation of different material.The structure of horizontal rotor body is split type to be made up of parts such as rotor block, hanging pin, collars at present,
Hanging pin is arranged on rotor block and fixed by collar.Existing rotor machining mode first processes a portion using the mach mode of tradition
Part, then assemble, this mode both waste of materials, process-cycle length, and cost is very high；Rotor quality is very big simultaneously, adds
The big load of motor；Under special use environment, existing rotor block also extremely gets rusty easily.Led with the application of centrifuge
Domain is more and more extensive, and also more and more higher, traditional split type horizontal rotor are no longer suitable for requirement of the people to the rotor of centrifuge
With.
Utility model content
The purpose of this utility model is to provide the centrifuge horizontal rotor that a kind of production cost is low, precision is high.
Realize that the technical scheme that the utility model purpose uses is as follows：
Centrifuge horizontal rotor provided by the utility model, including the rotor block that is integrated of casting and hanging pin, it is described
Rotor block is included positioned at middle installation basal disc, some ribs for being located at basal disc periphery, the fork-shaped hanging head for being located at rib outer end, institute
Hanging pin is stated to be symmetrically arranged on the hanging head.
Fan-shaped reinforcement is provided between the fork-shaped hanging head.
The rotor block uses identical thickness H, and the vertical height of the rib is equal to the thickness H of rotor block, described turn
The thickness H of daughter and the horizontal width D of rib pass through formula σ max=F1/（H*D）Calculating, wherein σ max are material yield strength,
F1 is maximum centrifugal force.
The diameter d of the hanging pin, formula W z=π * d can be passed through3/ 32 calculate, and wherein Wz is material bending resistant section coefficient.
The beneficial effects of the utility model
1st, the utility model can use hot investment casting one-shot forming, the weight saving of rotor block, reduce centrifuge in work
The load of motor when making, extend the service life of motor.
2nd, due to hot investment casting one-shot forming can be used, ensure that hanging pin relative to center precision while, rotor
Body both saves material, shortens the process-cycle again, cut without being hung in man-made assembly, save cost without processing.
The technical solution of the utility model is further illustrated below in conjunction with the accompanying drawings.
Brief description of the drawings
Fig. 1 is front view of the present utility model.
Fig. 2 is Fig. 1 left view.
In figure：1. install basal disc, 2. ribs, 3. fork-shaped hanging heads, 4. hanging pins, 5. fan-shaped reinforcements, d. hanging pins diameter,
D. rib width, the thickness of H. rotor blocks.
Embodiment
See rotor block that Fig. 1, Fig. 2, centrifuge horizontal rotor provided by the utility model, including casting be integrated and
Hanging pin 4, the rotor block include positioned at middle installation basal disc 1, are located at four ribs 2 on the periphery of basal disc 1, are located at outside rib 2
The fork-shaped hanging head 3 at end, fan-shaped reinforcement 5 is provided between fork-shaped hanging head 3, the hanging pin 4 is symmetrically arranged on the hanging head 3.
The rotor block uses identical thickness H, and the vertical height of the rib is equal to the thickness H of rotor block, described turn
The thickness H of daughter and the horizontal width D of rib pass through formula σ max=F1/（H*D）Calculating, wherein σ max are material yield strength,
F1 is maximum centrifugal force, and H is rotor thickness, and D is four rib widths.In σ max, F1, H, rib can be calculated in the case of known
The width D of bar.
The diameter d of the hanging pin 4, formula W z=π * d can be passed through3/ 32 calculate, and wherein Wz is material bending resistant section coefficient, d
For hanging pin diameter, in Wz, hanging pin diameter d can be calculated in the case of π is known.
The utility model can be molded by hot investment casting, and rib and hanging pin are all without processing, the precision that hot investment casting reaches
Also comply with centrifuge rotor and use standard.
