Abstract
A low-disturbance mechanical connection structure is characterized in that a flange is made of titanium alloy TC4 materials; the flange is connected with a gear shaft through an inner spline and an outer spline, a cylindrical positioning surface I is arranged at the front portion of the flange, a cylindrical positioning surface II is arranged at the rear portion the flange, and the cylindrical positioning surface I and the cylindrical positioning surface II are matched with the gear shaft; the cylindrical surface of the flange is matched with oil seal to seal oil; two bearings are arranged at the front portion and the rear portion of the gear shaft. The low-disturbance mechanical connection structure has the advantages that by means of the low-disturbance mechanical connection structure, dynamic power caused by an input-output connection structure of the gear shaft can be reduced, and problems of large dynamic power and vibration exceeding of a gear transmission device at high speed can be effectively solved.
Description
technical field:
The utility model relates to the common rotating machinery technical field of structures of machinery, refers in particular to a kind of low disturbance mechanical coupling structure.
background technique:
Gear drive is widely used in machinery field at present, and some gear drives, the feature of there is high rotating speed input, exporting, its connecting structure generally adopts integral flange or dries hollow flange.Integral (type) flange connecting structure is excessive, while adopting rolling bearing supporting gear axle, cause assembling, and its material must select Pinion Steel, and weight is larger, and at a high speed lower disturbance is large.Dry hollow flange and can select different flange material, the quality of flange is alleviated, but be generally only applicable to the slow-speed of revolution, little moment of torsion operating mode, the centrifugal force under high rotating speed can make flange and gear shaft get loose, and dismantles that to reassemble bearing very inconvenient.Therefore, need a kind of switching mechanical structure, can meet the low disturbance demand under compact structure, high rotating speed, make again convenient disassembly.
model utility content:
The purpose of this utility model is to provide a kind of low disturbance mechanical coupling structure, solves that existing flanged connecting structure can not meet structure set compactness, lightweight, high rotating speed bends down the advantage work requirements problems such as disturbance, convenient disassembly.
The purpose of this utility model realizes as follows: a kind of low disturbance mechanical coupling structure, mainly by flange, oil sealing, fore bearing, gear shaft, rear bearing, formed, and it is characterized in that: flange adopts titanium alloy TC 4 material; Flange and gear shaft adopt inside and outside splined, are provided with cylinder locating face I in the front portion of flange, are provided with cylinder locating face II at the rear portion of flange, and front and back locating face I, II coordinate with gear shaft; The periphery of flange coordinates oil sealing with oil sealing; Two bearings are separately positioned on the front and rear part of gear shaft.
The beneficial effects of the utility model are, have adopted low density, high strength flange material, and flange adopts titanium alloy material, and quality is light, intensity is high, and the dynamic force causing due to factors such as imbalances is little; And because the volume of flange is relatively little, manufacture cost is relatively low; Adopted the connecting mode of spline torsion pass, excircle orientation; Between flange and gear shaft, adopt inside and outside splined form, the front side of flange, rear side arrange respectively excircle orientation face and coordinate with gear shaft, reach the demand of high pulling torque torsion pass, hi-Fix, reduced the dynamic centrifugal disturbance causing due to factors such as processing, assemblings, and dismantled very convenient; By low disturbance mechanical coupling structure, can reduce gear shaft input output connecting structure and the dynamic disturbances power that produces, effectively solve the problem that high rotating speed lower gear transmission device dynamic force is excessive, vibration noise exceeds standard.
accompanying drawing explanation:
Fig. 1 is the utility model structural representation;
In figure: flange 1, oil sealing 2, fore bearing 3, gear shaft 4, rear bearing 5.
embodiment:
With reference to Fig. 1, a kind of low disturbance mechanical coupling structure, is mainly comprised of flange 1, oil sealing 2, fore bearing 3, gear shaft 4, rear bearing 5, it is characterized in that: flange 1 adopts titanium alloy TC 4 material; Flange 1 adopts inside and outside splined with gear shaft 4, is provided with cylinder locating face I in the front portion of flange 1, is provided with cylinder locating face II at the rear portion of flange 1, and front and back locating face I, II coordinate with gear shaft 4; The periphery of flange 1 coordinates oil sealing with oil sealing 2; Fore bearing 3, rear bearing 5 are separately positioned on the front and rear part of gear shaft 4.
This model utility has adopted low density, high strength flange material, and flange 1 adopts titanium alloy material, and quality is light, intensity is high, and the dynamic force causing due to factors such as imbalances is little; And because the volume of flange 1 is relatively little, manufacture cost is relatively low; Adopted the connecting mode of spline torsion pass, excircle orientation; Between flange 1 and gear shaft 4, adopt inside and outside splined form, the front side of flange 1, rear side arrange respectively excircle orientation face and coordinate with gear shaft 4, reach the demand of high pulling torque torsion pass, hi-Fix, reduced the dynamic centrifugal disturbance causing due to factors such as processing, assemblings, and dismantled very convenient; By low disturbance mechanical coupling structure, can reduce gear shaft 4 input output connecting structures and the dynamic disturbances power that produces, effectively solve the problem that high rotating speed lower gear transmission device dynamic force is excessive, vibration noise exceeds standard.
