A kind of supporting construction
Technical field
The present invention relates to mechanical equipment technical field, more particularly, to a kind of supporting construction.
Background technology
In plant equipment, motor uses usually as power set, and the power of motor is exported by output shaft, in order to protect
Hold the balance of motor output shaft, need output shaft is supported.In prior art, typically by bearing, output shaft is installed
In frame, realize the support of output shaft.In said structure, the position due to frame is often fixing, leads to output shaft
The strong point cannot be carried out select, not good to the support effect of output shaft, need to improve.
Content of the invention
In order to solve technical problem present in background technology, the present invention proposes a kind of supporting construction it is achieved that to electricity
The support of machine output shaft, support effect is good.
A kind of supporting construction proposed by the present invention, including motor, bracing frame and frame, bracing frame includes and motor output shaft
Vertical main shaft and at least fulcrum parallel with motor output shaft, frame have link slot and power supply machine output shaft pass through
First through hole, main shaft is provided with the second through hole, motor output shaft passes through the second through hole fixing, the groove of link slot with main shaft
Bottom has first annular groove corresponding with fulcrum, and fulcrum one end is fixed with main shaft and the other end inserts in the first corresponding annular groove.
Preferably, also include first baffle and second baffle, fulcrum is provided with a ring recess wall parallel to the second of main shaft
Annular groove, first baffle and second baffle be annular solid and first baffle and second baffle all and main axis parallel, fulcrum is located at first
Between baffle plate inner circumferential and second baffle periphery, first baffle inner circumferential and second baffle periphery are all inserted in the second annular groove.
Preferably, fulcrum periphery is provided with bearing, and bearing outer peripheral face with the first annular groove cell wall linear contact lay.
Preferably, bracing frame includes two fulcrums, and two fulcrums are symmetrically distributed in motor transmission shaft both sides.
In the present invention, with bracing frame, motor output shaft is supported, such that it is able to optimal according to motor output shaft
Support position, can select suitable bracing frame, overcome the shortcoming that rack construction is difficult to change;Motor output shaft and bracing frame
Main shaft is fixed, and bracing frame rotates with motor output shaft and rotates, and meanwhile, is provided with link slot in frame, and in link slot
Bottom land is provided with the first annular groove of the axis rotation for bracing frame, and forms support by the first annular groove to fulcrum, thus
Motor output shaft is formed and supports.
Brief description
Fig. 1 is a kind of schematic diagram of supporting construction proposed by the present invention;
Fig. 2 is the partial structural diagram of frame in Fig. 1.
Specific embodiment
As depicted in figs. 1 and 2, Fig. 1 is a kind of schematic diagram of supporting construction proposed by the present invention;Fig. 2 is frame in Fig. 1
Partial structural diagram.
With reference to Fig. 1 and combine Fig. 2, a kind of supporting construction proposed by the present invention, including motor 1, bracing frame 2 and frame 3,
Support 2 includes the main shaft 21 vertical with motor 1 output shaft 8 and at least one fulcrum 22 parallel with motor 1 output shaft 8, frame 3
On there is the first through hole that link slot and power supply machine 1 output shaft 8 pass through, main shaft 21 is provided with the second through hole, motor 1 output shaft
8 are passed through the second through hole and are fixed with main shaft 21, and the bottom land of link slot has first annular groove 7 corresponding with fulcrum 22, fulcrum 22 one end
In the first annular groove 7 that main shaft 21 is fixing and other end insertion is corresponding.
In the above-described embodiments, with bracing frame 2, motor 1 output shaft 8 is supported, such that it is able to be exported according to motor 1
The maximum support position of axle 8, can select suitable bracing frame 2, overcome the shortcoming that frame 3 structure is difficult to change;Motor 1 is defeated
Shaft 8 is fixing with the main shaft 21 of bracing frame 2, and bracing frame 2 rotates with motor 1 output shaft 8 and rotates, and, arranges in frame 3 meanwhile
There is a link slot, and the first annular groove 7 that rotates of the fulcrum 22 that is provided with for bracing frame 2 of bottom land in link slot, and by
One annular groove 7 forms to fulcrum 22 and supports, thus motor 1 output shaft 8 is formed supporting.
In further improved technical scheme, also include first baffle 9 and second baffle 10, fulcrum 22 is provided with one
Parallel to the second annular groove 11 of main shaft 21, first baffle 9 and second baffle 10 are annular solid and first baffle 9 and second to ring recess wall
Baffle plate 10 is all parallel with main shaft 21, and fulcrum 22 is located between first baffle 9 inner circumferential and second baffle 10 periphery, in first baffle 9
Week and second baffle 10 periphery are all inserted in the second annular groove 11, and in said structure, first baffle and second baffle 10 can prevent
External dust enter the first annular groove 7 in so that fulcrum 22 run in the first annular groove 7 more smooth.
In further improved technical scheme, fulcrum 22 periphery is provided with bearing 4, and bearing 4 outer peripheral face with first
Annular groove 7 cell wall linear contact lay, in above-mentioned design, can reduce the abrasion of fulcrum 22, both the first annular groove 7 cell walls by bearing 4.
In further improved technical scheme, bracing frame 2 includes two fulcrums 22, and two fulcrums 22 are symmetrically distributed in
Motor 1 power transmission shaft both sides, said structure is simple and good stability.
The above, the only present invention preferably specific embodiment, but protection scope of the present invention is not limited thereto,
Any those familiar with the art the invention discloses technical scope in, technology according to the present invention scheme and its
Inventive concept equivalent or change in addition, all should be included within the scope of the present invention.
