Abstract
The utility model relates to a high-speed rotator supporting mechanism, which comprises a transmission shaft, and is characterized in that three evenly distributed constraint wheels contacting with the transmission shaft are arranged on the circumference of a supporting position of the transmission shaft, the three constraint wheels are mounted on respective bearings respectively, and the diameter of each constraint wheel is 1.5-10 times of the shaft diameter of the supporting position of the transmission shaft. The rotational speed of the transmission shaft can be transferred to the supported bearings through the constraint wheels, and the diameter of each constraint wheel is larger than the shaft diameter of the supporting position of the transmission shaft by a multiple larger than one, namely the rotational speed of the constraint wheels is in lowered multiple relationship relative to that of the transmission shaft, so that the rotational speed of the constraint wheels is within the limit rotational speed range allowed by the bearings. Therefore, the high-speed rotator supporting mechanism has the advantages of reasonable structure, long service life and the like, and is especially applicable to filament throwing roll shafts for supporting a refractory fiber filament throwing machine.
Description
Technical field
The utility model belongs to driving mechanism, is a kind of high speed rotary body supporting mechanism.
Background technique
In driving mechanism, adopt the supporting part of bearing usually as solid of rotation, but for high-revolving transmission shaft, for example: transmission shaft rotating speed＞10000 rev/min, when the transmission shaft of high speed rotary directly is installed on the bearing, the normal limit speed that exceeds the bearing permission because of the rotating speed of transmission shaft is too high, will reduce the working life of bearing, even cause the generation of accident because of damage of bearings.
Summary of the invention
The purpose of this utility model is to provide a kind of rational in infrastructure, the high speed rotary body supporting mechanism of long service life.
The purpose of this utility model is realized by following technological scheme: a kind of high speed rotary body supporting mechanism, it comprises transmission shaft, it is characterized in that: setting contacts with it and three uniform constraint wheels on the circumference of transmission shaft Support Position, and three constraints are taken turns on the bearing that is loaded on respectively separately.
The diameter of described constraint wheel is 1.5～10 times of the transmission shaft Support Position diameter of axle.
High speed rotary body supporting mechanism of the present utility model, contact with it owing to adopt on the circumference of transmission shaft Support Position, to be provided with, and three uniform constraint wheels, three constraints are taken turns on the bearing that is loaded on respectively separately, the rotating speed of transmission shaft passes to the bearing of support by the constraint wheel, because the diameter of constraint wheel is greater than the diameter of axle of transmission shaft Support Position, the diameter of constraint wheel and the transmission shaft Support Position diameter of axle are the multiple relation greater than 1, that is the rotating speed of the relative transmission shaft of rotating speed of constraint wheel is the multiple relation that reduces, the rotating speed that causes the constraint wheel is in the limit speed scope that bearing allows, therefore, have rational in infrastructure, advantages such as long service life are specially adapted to support the wire swaying roller axle of refractory fiber tumbling machine.
Description of drawings
Fig. 1 is a high speed rotary body supporting mechanism structural representation of the present utility model.
Fig. 2 is A-A cross-sectional schematic among Fig. 1 (two supporting form).
Fig. 3 is B-B cross-sectional schematic among Fig. 1 (single supporting form).
Embodiment
The utility model is described in further detail to utilize drawings and Examples below.
With reference to Fig. 1-3, high speed rotary body supporting mechanism of the present utility model has transmission shaft 2, contacts with it and uniform 3, three constraints of three constraint wheels are taken turns on 3 bearings 1 that are loaded on respectively separately being provided with on the circumference of transmission shaft 2 Support Positions.The diameter of described constraint wheel 3 is 1.5～10 times of the transmission shaft 2 Support Position diameters of axle.The transmission shaft 2 of this embodiment adopts two supporting forms.Also can single supporting form be set for the short pass moving axis in the intermediate support position of short pass moving axis.
High speed rotary body supporting mechanism of the present utility model does not limit to this embodiment, and those skilled in the art all belong to protection domain of the present utility model without any simple transformation of creative work.
