Abstract
The utility model relates to a sealed synchronous wave motion transmitting equipment used for toxic, combustible or explosive media, which changes traditional rotary sealed manner. A flexible sealed tube is fixed on a flange; motive power is transmitted and output by a wave motion; an input shaft and an output shaft have good synchronization. Without a leaky rotating clearance, the utility model solves the economic loss of leak in industries, stops the occurrences of accidents such as fire, detonation, poisoning and pollution which are resulted from the leak of various harmful media and ensures personnel safety and production safety.
Description
The utility model is the device of relevant sealing synchronization fluctuate transmission, is specially adapted to poisonously, and inflammable and explosive is the mechanical transmission of medium.
The existing mechanical driving mechanism is though seal arrangement is of a great variety, because the relative movement of transmission shaft and Sealing certainly exists running clearance, thereby just can not thoroughly address the leakage concern.
The purpose of this utility model provides a kind of mechanical transmission of positive confinement, to prevent the leakage problem of medium.
Scheme of the present utility model is to be power input shaft (18) by wave-generator, flexible sealing tube and synchronous waves receiver are that the cam (12) on the pto is formed, input shaft (18) has ellipse garden shape or involute shape endoporus, flexible bearing (8) wherein is housed, the outer shroud of flexible bearing (8) and hole, ellipse garden or involute shape hole are equipped, ring is equipped with the outer garden of the flexible sealing tube of fixing (10) in it, and this just makes flexible sealing tube (10) that resiliently deformable takes place and forms the inner chamber of an ellipse garden shape or involute shape.The outer shroud of flexible bearing (9) and sealing drum (10) are equipped, and interior ring and profile are that the cam (12) of ellipse garden shape or involute shape is equipped, and cam connects with output shaft (1) by elastic coupling flexible coupling (28).Flexible sealing tube (10) is to be fixed on the flange plate (16), when input shaft rotates, wave-generator forces flexible sealing tube (10) that resiliently deformable takes place continuously, form the inner chamber of an ellipse garden shape of rotating continuously or involute shape and the synchronous waves receiver occupies this space, thereby promote synchronous receiver and wave-generator rotates synchronously.
The utility model has been broken traditional mechanical seal mode, does not have running clearance, and when medium released between output shaft (1) and oil sealing (2), the flexible sealing tube (10) that is fixed on flange plate (16) was fully isolated.Medium can not release with extraneous and contact.
Fig. 1 is the erection drawing of mechanism.
Fig. 2 is the A-A sectional view.
With reference to Fig. 1 and Fig. 2 critical piece of the present utility model be: (2) are oil sealing; (3) be seal ring; (4) be bearing support; (5) be seal ring; (6) be end cap; (11) (13) are check ring; (14) be screw; (15) be bolt.
Accompanying drawing 1 has been described an embodiment of the present utility model:
Power input shaft (1) is by bearing (7) location, and bearing (7) is installed on the centring sleeve (4), and centring sleeve is fixed on the flange plate (16).On flange plate, the endoporus and the cam (12) of input shaft and flexible bearing (8) assembling place are involute shapes to output shaft (1) by bearing (20) location and installation.When rotating, power input shaft force the flexible sealing tube (10) that is fixedly mounted on the flange plate and the outer shroud of flexible bearing (9) to recur resiliently deformable, form the involute shape inner chamber that rotates, this inner chamber is occupied by cam (12) fully, and cam is connected by elastic coupling flexible coupling with output shaft (1), the institute so that output shaft and input shaft rotate synchronously.
Claims (3)
1, a kind of centring sleeve is fixed on the sealing synchronization fluctuate driving mechanism on the flange plate, the endoporus that it is characterized in that input shaft and flexible bearing (8) assembling place is an ellipse garden shape, the interior ring of flexible bearing (8) and flexible sealing tube (10) are equipped, the flexible sealing tube is fixed on the flange plate (16), the outer shroud of flexible bearing (9) and flexible sealing tube are equipped, interior ring is equipped with the cam (12) of ellipse garden shape, and cam and output shaft (1) link.
2, sealing synchronization fluctuate driving mechanism according to claim 1 is characterized in that the endoporus and the cam (12) of assembling place of input shaft and flexible bearing (8) can be involute shape.
3, sealing synchronization fluctuate driving mechanism according to claim 1 and 2 is characterized in that cam (12) is to link by elastic coupling flexible coupling (28) and output shaft (1).
