Description
Technical field
The invention belongs to the device of hole sealing, and in particular to a kind of constant speed friction synchronous rotary sealing device, it is especially suitable
Sealed in dynamic aperture.
Background technology
Current hole sealing device is gradually perfect, but service life is not grown.Especially when sealing dynamic object, due to
The presence of friction, service life substantially reduce.Conventional dynamic dynamic sealing, takes annular seal lip.There are during relative motion, seal
Lip is easily damaged, and service life is shorter.When rods rotates at a high speed, ring wear caused by friction is inevitable, thus
Short period needs are caused to substantially reduce sealing effect with changing sealing ring.This technology is intended to carry out Kong Mi by circulation seal band
Envelope, while leakproofness is ensured, greatly improves service life.By the rotation of object itself, band is driven to rotate, so that
Reach interaction conversion in sealing contact.It is primarily adapted for use in the situation that rods rotates about the axis.
The content of the invention
A kind of hole sealing device of and service life preferable it is an object of the invention to provide sealing effect length.
The solution for realizing the object of the invention is:
A kind of constant speed friction synchronous rotary sealing device, including shape of threads matrix, closing seam band, pulley;Wherein, it is used for
The shape of threads matrix of fixed enclosed article part is equipped with thread-like groove, while equipped with flight pitch control device for controlling screw thread
The spacing of shape groove;Three pulleys are respectively equipped with using centered on shape of threads matrix and are installed on screw thread as stent, closing seam band
On shape groove and three pulleys, closing seam band is set to form multiple-turns wound in thread-like groove;And by adjustable pulley position,
Increase closing seam band treats the pressure of envelope object.
Further, the pulley in three pulleys close to flight pitch control device is equipped with the dress for adjustable pulley height
Put, change the elastic of band.
Further, fibre core built in closing seam band, for preventing in seal process, closing seam band is broken suddenly,
Sealing system is collapsed, and the presence of fibre core can ensure that sealing function is more stablized.
Further, built-in fibre core metal and the higher high molecular material of toughness, preferably iron core.
Further, square shape is taken in closing seam band section, for strengthening the leakproofness perpendicular to axis direction
Energy.
Compared with prior art, the present invention its remarkable advantage:1st, the service life length of sealing device provided by the invention, no
Replaced with short-term, by the rotation of object itself, drive band to rotate, so as to reach interaction conversion in sealing contact.Make closure
The same position of band will not be subject to continuous frictional, so as to improve sealing life;2nd, suitable for the object of various scope diameters;3、
Sealing device can adjust sealing belt tension so as to change the frictional force to object.

Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
According to Fig. 1, the invention discloses a kind of constant speed friction synchronous rotary sealing device, including shape of threads matrix, closure
6, three pulleys of band are respectively pulley 1, pulley 23, pulley 37.For fixing the shape of threads matrix 2 of enclosed article part
Equipped with thread-like groove, while the spacing equipped with flight pitch control device 4 for controlling thread-like groove;With shape of threads matrix
Centered on be respectively equipped with three pulleys, closing seam band 6 is installed on thread-like groove 2 and three pulleys 1,3,7 and passes through tune
Pulley position is saved, increase closing seam band treats the pressure of envelope object.By 7 position of adjustable pulley, increase the tension force of band,
So as to improve sealing effect.Pulley 1,3,7 plays the role of the stent of band.In addition to pulley provided by the invention, this hair
It is bright to replace other any mechanisms that can be acted on as stent;Fibre core built in closing seam band 6, for preventing from sealing
During, band is broken suddenly, sealing system collapse.The presence of fibre core can ensure that sealing function is more stablized.Between screw thread
Distance control apparatus 4 is used for according to 6 bandwidth fixed groove spacing of band, to improve sealing effect.
During work, it will be inserted in by sealing rods 5 in shape of threads matrix, if Fig. 2 is shape of threads matrix, band, which twines, is attached to spiral shell
In line shape groove, by the position of adjustable pulley 37, band is stretched, and pressure is applied to object by band, makes sealing
Belt tension increase, so as to reach sealing effect.
Fig. 3 is closing seam band sectional view, has circular iron core at the center in section, for stabilized seal band, is improved close
The stability of envelope.Band material uses PU polyurethane rubbers, and the mechanical performance of polyurethane rubber is very good, wear-resisting, high pressure resistant
Performance is much better than other rubber.Resistance to ag(e)ing, ozone resistance, oil resistivity are also fairly good.
Fig. 4 is pulley regulating device, by adjusting the height of lower section pulley, changes the elastic of band, so as to influence close
Seal effect.
