Description
Technical field
The invention belongs to cooling tower technical field, specially it is a kind of can the belt used for cooling tower installed of arbitrary orientation slow down
Device.
Background technology
Cooling tower is to drive blower fan to make air flow to take away recirculated water heat using decelerator, to realize recirculated water cooling
But device.Cooling tower structure is various informative, and different types of cooling tower is equipped with different requirements to the installation position of decelerator, subtracts
Fast device Impact direction is different, and corresponding Bearing configuration and seal request are different, and a kind of decelerator can not realize that various orientation are installed,
Decelerator damage is otherwise easily caused, therefore different types of cooling tower needs the decelerator of multiple structural forms and configuration.
Existing cooling tower belt reducer, in operation main shaft stress be mainly radially --- belt tension, axle
To --- blower fan thrust, in addition decelerator and its blower fan of driving make gravity be divided in portion radial and axial depending on installation position
On, radial force and axial force it is all relatively large.
Fig. 1 show that existing belt reducer is vertically-mounted, the situation that blower fan 60 is installed down.Housing 1 is arranged on to be installed
On frame 50, because the stress of top belt shaft 3 is belt tension Fx, the upper end adapted deep groove ball bearing 4 of main shaft 2, generally this deep-groove ball axle
Hold as totally enclosed type or semi-enclosed, to ensure that the grease for running middle (center) bearing is not lost in decelerator cavity, otherwise zanjon
Ball bearing 4 can be damaged because of disappearance lubrication, so as to cause decelerator trouble to run.The lower end adapted deep groove ball bearing 4 of main shaft 2
Plus the combination of single direction thrust ball bearing 5, power F of the carrying vertical direction of single direction thrust ball bearing 5y。
Fig. 2 is that existing belt reducer is vertically-mounted, the situation that blower fan 60 is installed upward.Because of axial force suffered by main shaft 2
Direction is different, and internal bearing installation position is also different, therefore Fig. 1 can not exchange installation with two kinds of decelerators of Fig. 2.
In the existing cooling tower belt shown in Fig. 1 and Fig. 2 slows down, the group of deep groove ball bearing 4 plus single direction thrust ball bearing 5
Close to carry radial load and axial load.Operationally centrifugal force is big because of rolling element for thrust ball bearing, and the life-span is shorter.Generally exist
The joint born axially and radially carries bearing when closing and adopts taper roll bearing more reliable, possesses the power train of good lubrication condition
Widely use in system, but without adopting on existing cooling tower belt reducer, the reason for be mainly based upon lubricating condition, circular cone
Roller bearing is open bearing, and itself is not furnished with sealing, it is impossible to ensure bearing lubrication.
The content of the invention
It is an object of the invention to provide a kind of cooling tower belt reducer that can be installed with arbitrary orientation, simple structure, fortune
Row is reliable, long service life.
To realize object above, the technical solution used in the present invention is：It is a kind of can arbitrary orientation install skin used for cooling tower
Band decelerator, it includes the main shaft (2) being arranged in housing (1)；Described main shaft (2) one end is provided with blower fan (60)；The shell
It is provided with taper roll bearing (14) in the bearing groove (19) at body (1) two ends to coordinate with main shaft (2)；Housing (1) two ends set
Oil seal groove (18) is equipped between two bearings groove (19)；Inner oil seal (17) and main shaft (2) are provided with the oil seal groove (18)
It is connected；The taper roll bearing (14) is fixed by the hubcap (6) for being fixed on housing (1) outboard end.
Further, the inner oil seal (17) is oil seal without framework.
Further, inner oil seal (17) cross section is U-shaped.
Further, the taper roll bearing (14) is symmetrically installed.
Further, it is provided with end cap oil sealing (7) between the hubcap (6) and main shaft (2).
Beneficial effects of the present invention：
Compared with prior art, the present invention adopts taper roll bearing using input, outfan, can carry arbitrary orientation
Load, i.e. belt reducer can arbitrary orientation installations.Bigger connected load can be carried using taper roll bearing, operation can
Lean on, long service life.Can be carried out by special mounting means realization each bearing chamber on the belt reducer of integral type close
Envelope, the selection to bearing is unrestricted.

Specific embodiment
In order that those skilled in the art more fully understand technical scheme, the present invention is entered below in conjunction with the accompanying drawings
Row is described in detail, and the description of this part is only exemplary and explanatory, should not there is any restriction to protection scope of the present invention
Effect.
As in Figure 3-5, concrete structure of the invention is：It is a kind of can arbitrary orientation install belt used for cooling tower slow down
Device, it includes the main shaft 2 being arranged in housing 1；The one end of the main shaft 2 is provided with blower fan 60；The bearing groove at the two ends of the housing 1
Taper roll bearing 14 is provided with 19 to coordinate with main shaft 2；The two ends of the housing 1 are provided with oil seal groove 18 positioned at two bearings groove 19
Between；Inner oil seal 17 is provided with the oil seal groove 18 to be connected with main shaft 2；The taper roll bearing 14 is by being fixed on
The hubcap 6 of the outboard end of housing 1 is fixed.
Preferably, the inner oil seal 17 is oil seal without framework.
Preferably, the cross section of the inner oil seal 17 is U-shaped.
Preferably, the taper roll bearing 14 is symmetrically installed.
Preferably, end cap oil sealing 7 is provided between the hubcap 6 and main shaft 2.
The principle of the invention：
It is as shown in Figure 3 it is a kind of can the cooling tower belt reducer installed of arbitrary orientation, including reducer shell 1, main shaft
2, belt pulley 3, hubcap 6, end cap oil sealing 7, taper roll bearing 14, inner oil seal 17 is bolted and is integrated.
Installed face-to-face using taper roll bearing 14 in power input, the outfan of main shaft 2, main shaft 2 transmits power
No matter axially or radially being undertaken by least one taper roll bearing, taper roll bearing 14 has can carry larger axle
To the characteristic of, radial force, because of linear contact, large carrying capacity, retarder operation reliability, long service life are can guarantee that.
The indoor design of reducer shell 1 is fluted, and inner oil seal 17 is arranged on recessed set by the inner chamber both sides of reducer shell 1
In groove, to seal to taper roll bearing 14, it is ensured that grease is not lost to the chamber of reducer shell 1 in running
In vivo.It is seen in figure 3 that the overall dimensions ￠ 2 of inner oil seal 17 is greater than the chi of the axis hole ￠ 1 that reducer shell 1 is opened up
It is very little.From nitrile rubber material, excellent spring is easily deformed inner oil seal 17 using it in the case where being acted on by external force, removes external force
The speciality of resilient.
As shown in Fig. 5 schematic diagrams, oil seal without framework 17 is installed into exoskeletal into making by using external force during reducer shell 1
Oil sealing 17 is changed into spill in radial shape, the overall dimensions of the oil seal without framework after deformation 17 is opened less than reducer shell 1
If axis hole ￠ 1 size, the oil seal without framework 17 after deformation is installed to the groove set by the inner chamber both sides of reducer shell 1
When interior, removing external force makes oil seal without framework 17 recover original-shape.Can complete to install.
By applying outer its deformation of external force to oil seal without framework 17 so as to can be by the hole less than own dimensions being installed to
In the oil seal groove of reducer shell 1.
