Abstract
The invention discloses a kind of structures for preventing impeller to be eccentrically rotated, it is mounted between gear-box and impeller, including sleeve and coupling lever, its middle sleeve both ends is installed with bearing block, and bearing is embedded in bearing block, coupling lever is inserted into the bearing at both ends, the output shaft cooperation of one end and gear-box, bearing block is fixed with gear-box simultaneously, and the other end of coupling lever is equipped with impeller.The present invention fixes the both ends of coupling lever using the bearing block realization at tube structure cooperation both ends, increases the installation stability to impeller, eliminates its eccentric rotational force.
Description
Technical field
The invention patent relates to a kind of coupling structures, and in particular to a kind of structure for preventing impeller to be eccentrically rotated.
Background technique
In the reduction pond of sewage treatment, need to cooperate agitator arm to be stirred the liquid in pond by gear-box,
Since agitator arm length has 1 ~ 2 meter long, so need very big torsion in stirring, and restores in pond and to be usually added one
A little reagents carry out reduction reaction, these reagents can adsorb to form crystallization in impeller surface after long-time, and crystal size position
It is all irregular, so impeller is caused the problem of discontinuity equalization occur, it is eccentrically rotated so as to cause impeller, since impeller is straight
It connects and is fixed with gearbox output shaft, so the eccentric rotational force of impeller passes to gearbox output shaft, so that gear-box is held
Other than by gravity, there are also eccentric rotational forces, so as to cause gear failure.
Summary of the invention
The purpose of invention: the purpose of the invention is to make up the deficiencies in the prior art, providing one kind prevents impeller eccentric
The structure of rotation fixes the both ends of coupling lever using the bearing block realization at tube structure cooperation both ends, increases the peace to impeller
Stability is filled, its eccentric rotational force is eliminated.
The technical solution adopted by the present invention: a kind of structure for preventing impeller to be eccentrically rotated, be mounted on gear-box and impeller it
Between, including sleeve and coupling lever, middle sleeve both ends are installed with bearing block, and bearing is embedded in bearing block, coupling lever inserting
In the bearing at both ends, the output shaft of one end and gear-box cooperates, while bearing block is fixed with gear-box, and coupling lever is another
One end is equipped with impeller.
Preferably, described coupling lever one end has the stop collar of evagination, and the end face at the end is equipped with and exports with gear-box
The slot of axis cooperation.
Preferably, the bearing block center is embedded with bearing, and surrounding has mounting hole, and outer edge has flange
Disk.
Preferably, the sleeve wall thickness is 5mm, the inner wall at both ends is equipped with multiple anti-skid bulges, while having and wearing
Saturating fixation hole.
The utility model has the advantages that a kind of disclosed structure for preventing impeller to be eccentrically rotated, has the following beneficial effects:
Increase the structure between gearbox output shaft and impeller, the connection of output shaft and impeller is realized by coupling lever, leaf can be promoted
The insertion depth of wheel, setting has the sleeve of bearing block outside coupling lever, and sleeve is fixed by bearing block and gear-box,
So that coupling lever realizes that both ends are fixed, so that the eccentric rotational force of impeller is eliminated after being transitioned into coupling lever, and then gear-box
Output shaft not will receive this eccentric force, so no matter how impeller is eccentrically rotated, gearbox output shaft only transmits torsion, without
Gravity and beat power (this power no longer acts on output shaft, but acts on the cabinet of gear-box) are born again, to protect
The gear structure in gear-box has been protected, has been prolonged its service life.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment
The specific embodiment of the invention is described in detail with reference to the accompanying drawing:
As shown in Figure 1, a kind of disclosed structure for preventing impeller to be eccentrically rotated, be mounted on gear-box and impeller it
Between, including sleeve 1 and coupling lever 2,1 both ends of middle sleeve are installed with bearing block 3, and bearing 4 is embedded in bearing block, coupling lever
It is inserted into the bearing at both ends, one end and gearbox output shaft cooperate, and the other end is equipped with impeller.
Particularly, the sleeve wall thickness is 5mm, and the inner wall at both ends is equipped with multiple anti-skid bulges 5, while having and wearing
Saturating fixation hole 6, the bearing block center is embedded with bearing, and surrounding has mounting hole 7, and outer edge has ring flange 8, institute
The stop collar 9 that coupling lever one end has evagination is stated, and the end face at the end is equipped with slot 10, and there is the other end diameter to reduce
The body of rod 11, and rod end is equipped with screw thread mounting groove 12.
When specific installation, coupling lever is inserted into a bearing block, and stop collar is close to bearing block, after assembling
In integral installation to the output shaft of gear-box, output shaft is inserted into slot at this time, and passes through fasteners through mounting holes 7 for axis
It holds seat to be fixed on the cabinet of gear-box, the rotary force of output shaft passes to coupling lever at this time, and sleeve is sleeved on outside coupling lever
Portion is stuck on bearing block, is passed through fixation hole by fastener and is fixed sleeve and bearing block, and the protrusion of sleeve lining increases at this time
Then coefficient of friction between bearing block installs another bearing block in the sleeve other end, so that the body of rod 11 of coupling lever is stretched
Out, which is fixed with sleeve, impeller is installed on the body of rod, being threaded into mounting groove by fastener can be realized
Integral installation.
Under the overall structure, impeller occurs after being eccentrically rotated, and gravity and beat power act directly on sleeve, also just passes
The cabinet of gear-box is passed, and for output shaft, it is only subjected only to rotary force, so protect internal gear.
The above is only a preferred embodiment of the present invention, it should be pointed out that: for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
