A kind of supporting construction
Technical field
The present invention relates to mechanical equipment technical field, particularly relate to a kind of supporting construction.
Background technology
In plant equipment, motor uses usually used as power set, and the power of motor is exported by output shaft, in order to keep the balance of motor output shaft, needs to support output shaft.In prior art, normally by bearing, output shaft is arranged in frame, realizes the support of output shaft.In said structure, the position due to frame is fixed often, causes the strong point of output shaft to select, not good to the support effect of output shaft, needs to improve.
Summary of the invention
In order to solve the technical problem existed in background technology, the present invention proposes a kind of supporting construction, achieving the support to motor output shaft, support effect is good.
A kind of supporting construction that the present invention proposes, comprise motor, bracing frame and frame, bracing frame comprises the main shaft vertical with the motor output shaft fulcrum parallel with motor output shaft with at least one, frame has the first through hole that link slot and power supply machine output shaft pass, main shaft is provided with the second through hole, motor output shaft passes the second through hole and fixes with main shaft, and the bottom land of link slot has first annular groove corresponding to fulcrum, and fulcrum one end is fixed with main shaft and the other end inserts in the first corresponding annular groove.
Preferably, also comprise the first baffle plate and second baffle, fulcrum is provided with the second annular groove that a ring recess wall is parallel to main shaft, first baffle plate and second baffle be annular solid and the first baffle plate and second baffle all and main axis parallel, fulcrum is between the first baffle plate periphery and second baffle inner circumferential, and the first baffle plate periphery and second baffle inner circumferential are all inserted in the second annular groove.
Preferably, fulcrum periphery is provided with bearing, and bearing outer peripheral face with at the first annular groove cell wall linear contact lay.
Preferably, bracing frame comprises 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, thus according to the maximum support position of motor output shaft, can select suitable bracing frame, overcome the shortcoming that rack construction is not easily changed; The main shaft of motor output shaft and bracing frame is fixed, bracing frame rotates with motor output shaft and rotates, simultaneously, frame is provided with link slot, and the first annular groove of the axis rotation for bracing frame is provided with at the bottom land of link slot, and by the first annular groove, support is formed to fulcrum, thus support is formed to motor output shaft.

Embodiment
As depicted in figs. 1 and 2, Fig. 1 is the schematic diagram of a kind of supporting construction that the present invention proposes; Fig. 2 is the partial structurtes schematic diagram of Fig. 1 mid frame.
With reference to Fig. 1 composition graphs 2, a kind of supporting construction that the present invention proposes, comprise motor 1, bracing frame 2 and frame 3, bracing frame 2 comprises the main shaft 21 vertical with motor 1 output shaft 8 fulcrum 22 parallel with motor 1 output shaft 8 with at least one, frame 3 has the first through hole that link slot 6 and power supply machine 1 output shaft 8 pass, main shaft 21 is provided with the second through hole, motor 1 output shaft 8 passes the second through hole and fixes with main shaft 21, the bottom land of link slot 6 has first annular groove 7 corresponding to fulcrum 22, fulcrum 22 one end fixes with main shaft 21 and the other end inserts in the first corresponding annular groove 7.
In the above-described embodiments, support with bracing frame 2 pairs of motor 1 output shafts 8, thus according to the maximum support position of motor 1 output shaft 8, can select suitable bracing frame 2, overcome the shortcoming that frame 3 structure is not easily changed; Motor 1 output shaft 8 is fixed with the main shaft 21 of bracing frame 2, bracing frame 2 rotates with motor 1 output shaft 8 and rotates, simultaneously, frame 3 is provided with link slot 6, and the first annular groove 7 supplying the fulcrum 22 of bracing frame 2 to rotate is provided with at the bottom land of link slot 6, and form support by the first annular groove 7 pairs of fulcrums 22, thus support is formed to motor 1 output shaft 8.
In the technical scheme improved further, also comprise the first baffle plate 9 and second baffle 10, fulcrum 22 is provided with the second annular groove 11 that a ring recess wall is parallel to main shaft 21, first baffle plate 9 is annular solid with second baffle 10 and the first baffle plate 9 and second baffle 10 are all parallel with main shaft 21, fulcrum 22 is between the first baffle plate 9 periphery and second baffle 10 inner circumferential, first baffle plate 9 periphery and second baffle 10 inner circumferential are all inserted in the second annular groove 11, in said structure, first baffle plate and second baffle 10 can prevent external dust from entering in the first annular groove 7, thus it is more smooth and easy to make fulcrum 22 run in the first annular groove 7.
In the technical scheme improved further, fulcrum 22 periphery is provided with bearing 4, and bearing 4 outer peripheral face with at the first annular groove 7 cell wall linear contact lay, in above-mentioned design, the wearing and tearing of both fulcrum 22, first annular groove 7 cell walls can be reduced by bearing 4.
In the technical scheme improved further, bracing frame 2 comprises two fulcrums 22, and two fulcrums 22 are symmetrically distributed in motor 1 power transmission shaft both sides, the simple and good stability of said structure.
The above; be only the present invention's preferably embodiment; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technical scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
