The device eliminates the intensive radial impact and the friction of a shaft, and the drastic vibration and the irregular circular motion of a mixing blade to reduce the power consumption and material consumption of the shaft, and extend the service life of the device.

Description

Energy-saving multisection stirring shaft fixing and running device

The utility model relates to axle, and particularly energy-conservation more piece shaft is fixed and rotating device.

Existing more piece shaft, its middle (center) bearing and the base bearing fixing and rotating device in stirred vessel is a sliding bearing, and it is with outer watt of dish, fixedly container center is satisfied with in lacing wire.The defective of this structure is: 1. for making shaft energy normal rotation, must stay suitable gap between inside and outside watt of sliding bearing, this gap easily causes the decentraction of axle to rotate, the liquid resistance that produces when making the stirring vane running on the axle substantially exceeds the resistance that produces when doing the motion of the vertical center of circle, thereby has increased the shaft work consumption greatly; 2. the out of plumb circular motion that the existence in inside and outside watt gap and major axis bottom produce makes Neva produce irregular impact for external watt, and the sliding friction between this impulsive force and inside and outside watt has increased the power consumption of axle and the wearing and tearing of bearing shell greatly.

The purpose of this utility model is that the fixing of existing more piece shaft improved with rotating device, and shaft power consumption and material consumption is reduced greatly, produces considerable energy saving consumption reduction effect.

The purpose of this utility model realizes with the rotating device design with following energy-conservation more piece shaft is fixing.This programme has mainly been done following improvement:

1. fixedly designed a clamping plate seat for middle (center) bearing.It is by upper and lower two fastening forming, clamping plate endosphere circle matches with the ectosphere circle of bottom bracket, make bearing block in the endosphere circle of clamping plate seat, can do the mutual motion of decentraction, in bearing block, also be provided with limit screw, the range of movement of this nail is limited in the vertical channel of clamping plate seat, does not do relative circular motion to guarantee bearing block and clamping plate seat only to do relative decentraction motion.

2. middle (center) bearing adopts single-row radial ball bearing, uses bolted on axle by axle sleeve.

3. be provided with twoport oil seal washer and felt circle in bottom bracket and the lower shaft bearing, and the extraordinary water resistant, high temperature resistant lubricating oil of contain.

4. base bearing adopts double-row radial ball bearing, and warp beam sleeve is anchored on the bottom of axle, has the automatic aligning function.

Fig. 4 is for existing more piece shaft middle (center) bearing, base bearing is fixed and the rotating device structural representation.

1. fixedly lacing wire 17. Neva cards 18 of 3. bottom brackets, 4. middle (center) bearings, 5. bearing caps, 6. cover plates, 7. bolts, 8. twoport oil seal washers, 9. felt circles, 10. axle sleeves, 11. base bearings, 12. lower shaft bearings, 13. shafts, 14. shaft couplings, 15. stirring vanes 16. are followed closely in 2. stop of clamping plate seat, 19. outer watts 20. outer watts dish seats of Neva, 21. container bottom tripods

Below in conjunction with accompanying drawing the utility model is further specified.As embodiment, shaft 13 usefulness middle (center) bearings 4, base bearing 11, clamping plate seat 1, fixedly lacing wire 16 and container bottom tripod 21 are installed on container center.Middle (center) bearing is a single-row radial ball bearing, because match with the ectosphere circle of bearing block 3 in the endosphere garden of clamping plate seat 1 and the effect of stop nail 2, make bearing block and clamping plate seat can only do relative decentraction motion, do not do relative circular motion, thereby guarantee still to do the stable garden heart motion when shaft is not orthogonal to container bottoms, avoid stirring vane 15 and liquid to produce bigger friction; Base bearing 11 warp beam sleeves 10 are anchored on a bottom, be installed on the container bottom tripod 21, be double-row radial ball bearing, have the automatic aligning function, when shaft is the major axis that more piece is linked to be, shaft coupling deformation, cause other position of axle to produce decentraction when the circular motion of container, the center of circle motion of standard still can be done in the base bearing position, and can also absorb the circular runout impulsive force that produces in the bottom when move in the vertical center of circle of major axis well, has guaranteed the life-span of base bearing; For stoping the liquid in the container to enter in the rolling bearing fully, with cover plate 6, bolt 7 with high resiliency twoport oil seal washer 8 and felt circle 9 compact package in bearing block, water-fast, the resistant to elevated temperatures lubricating oil of contain in the bearing block.

The utility model has the advantage of and eliminated violent radial impact and the friction of shaft that cause in inside and outside watt gap that make axle can do stable vertical center of circle motion, the friction of generation is minimum, thereby reduces shaft work consumption and material consumption; Eliminate strenuous vibration and the motion of irregular circumference of the multiple layers of stirring blades sheet that is installed on the axle, thereby greatly reduced the shaft work consumption, prolonged the service life of axle and stirring motor.
