Abstract
The utility model relates to a flexible coupler and belongs to the mechanical transmission filed. The flexible coupler is characterized by comprising an input flange (3) and an output flange (4) which are respectively in key connection with an input shaft (1) and an output shaft (2); an elastic nylon ring (5) is arranged between the input flange (3) and the output flange (4), one side thereof is fixed with the input flange (3), and the other side thereof is fixed with the output flange (4). In the utility model, the elastic nylon ring is taken as a flexible connecting shaft device; while the transmission is ensured, the radial distance between the input shaft and the output shaft can be adjusted within a certain scope, so that the instantaneous angular velocity between the input shaft and the output shaft is unchanged; and meanwhile, the transmitted torque can be greatly enhanced.
Description
Technical field
The utility model relates to a kind of transmission part, relates in particular to a kind of flexible coupling that is used for the single cylinder mini engine.
Background technique
In single cylinder miniature gasoline engine engine rig test process, because the very big characteristics of single-cylinder engine self vibration, make it in operation process, can not well keep centering between input shaft and the output shaft, and owing to can not well keep centering to cause warping force very big.Hitch bar such as Hooks coupling universal coupling commonly used can play the angle skew effect that compensates diaxon on the market now, but cushioning effect is limited; Though and there is the elastic element of damping the flexible coupling centre that has elastic element, shell etc. all are rigid members, when vibrations are very big, but all can not meet the demands to neutral and torsion proof performance.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of flexible coupling, and it is bad to solve existing coupling damping effect, when the defective that can not meet the demands to neutrality and torsion proof performance of the big back of external force vibrations coupling.
Technological scheme
A kind of flexible coupling, it is characterized in that: comprise the input flange 3 and the output flange 4 that are connected with output shaft 2 difference keys with input shaft 1, be stretchy nylon circle 5 between input flange 3 and output flange 4, described stretchy nylon circle 5 one sides and input flange 3 are fixing, and opposite side and output flange 4 are fixing.
Described input flange 3 and output flange 4 are the flange of same size size, adopt bolt 6 to fixedly connected with stretchy nylon circle 5.
There is disk gasket 7 described stretchy nylon circle 5 inboards with bolt 6 joints.
Respectively one of described disk gasket about 7, the cross section is more than or equal to the surface of contact sectional area of flange and stretchy nylon circle 5, and thickness is more than or equal to 5mm.
Described bolt 6 is four, is symmetrical distribution around the input output axle center.
Described stretchy nylon circle 5 uses damping capacity and the strong nylon material of bearing capacity to make.
The thickness of described stretchy nylon circle 5 is more than or equal to 20mm.
Beneficial effect
The utility model is as flexible coupling device with the stretchy nylon circle, when guaranteeing transmission, can realize that the radial distance between input shaft and the output shaft can regulate within the specific limits, guarantee that the instantaneous angular velocity between input shaft and the output shaft is constant, transmitting torque can strengthen greatly simultaneously, for the vibrations that produce owing to running owing to engine output shaft (being the input shaft of coupling), have obvious cushioning effect, the utility model also has obvious effect to input shaft and output shaft to requirement of neutral for reducing.

Among the figure: 1-input shaft, 2-output shaft, 3-input flange, 4-output flange, 5-stretchy nylon circle, 6-bolt, 7-disk gasket.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.
A kind of flexible coupling, comprise the input flange 3 and the output flange 4 that are connected with output shaft 2 difference keys with input shaft 1, be stretchy nylon circle 5 between input flange 3 and output flange 4, described stretchy nylon circle 5 one sides and input flange 3 are fixing, and opposite side and output flange 4 are fixing.
Described input flange 3 and output flange 4 are the flange of same size size, adopt M8 or M10 high-strength bolt 6 to fixedly connected with stretchy nylon circle 5.Bolt 6 adopts four, is symmetrical distribution around the input output axle center.For guaranteeing the reliable transmission of stretchy nylon circle 5, must answer sufficient length by assurance bolt 6 elasticity of extension nylon rings 5, and can compress.
There is disk gasket 7 described stretchy nylon circle 5 inboards with bolt 6 joints.Respectively one of described disk gasket about 7, for guaranteeing that connection is reliable and power transmission is even, the dish-type pad 7 that uses must have enough bearing areas, and the cross section is more than or equal to the surface of contact sectional area of flange and stretchy nylon circle 5, and thickness is more than or equal to 5mm.Disk gasket 7 can use components made of steel to increase its strength.
Described stretchy nylon circle 5 uses damping capacity and the strong high-strength nylon material of bearing capacity, must have big, wear-resisting, the anti-condition such as mildew and rot, high temperature resistant of intensity, and whole stretchy nylon circle 5 thickness homogeneous, and fitness for purpose is more than or equal to 20mm.The stretchy nylon band that can used thickness be 10mm is fixedly made around two circles or multi-turn.
Flexible coupling of the present utility model adopts stretchy nylon circle 5 as intermediate member between input shaft 1 and output shaft 2, can form good flexible transmission, for because the problems such as off-centre that cause of input shaft 1 can solve, and anti-seismic performance and bearing capacity strengthen greatly.And compact structure, to make simply, cost is low, suddenly stops at input shaft 1, anxious rising etc. under the situation, can also bear big moment of torsion and can not produce additional distortion.
In the experiment, around the two-layer fixing coupling of making as stretchy nylon circle 5, when the motor wheel speed reaches 4000 when changeing, this coupling can be resisted the moment of torsion of 20～30N.m with the stretchy nylon band of 10mm.Can be applied to the damping requirement than higher, resist the occasion of big warping force, similar single cylinder mini engine and power measurer etc.
