Abstract
The utility model relates to a revolving brake wheel which has a circular outer sheath, a brake wheel is positioned in the circular outer sheath, the middle of the brake wheel is provided with an axle hole, from 2 to 20 dihedral nicks with an angle of100 degrees are evenly arranged along the circumference of the brake wheel, the edge of the dihedral angles parallel with the axis of the brake wheel, the length of the bigger face of the dihedral angle is 2 to 4 times of the length of smaller face, the smaller face of the dihedral angle is provided with a round hole vertical to the face, the bottom of the round hole is provided with a spring that is connected with an ejector pin, the nicks are respectively provided with a plurality of column rollers inside, a circular cover gasket is arranged at two sides of the outer ring and the brake wheel. The utility model is positioned between a non contrarotating component and a fastening component. The revolving brake can revolve in positive direction, when the revolving brake revolves in opposite direction; the column rollers are pushed and deadly compressed in a comparatively small acute angle of the nicks by concentric component force, the column rollers are restricted to revolve so as that the circular outer ring will not revolve. When the utility model revolves in positive direction, the column rollers that function as brake are revolving, without any strike noise so as to supply a quiet environment.
Description
Technical field
The utility model relates to a kind of mechanical device, particularly a kind of rotation non-return device that can prevent the rotary component counterrotating on the machinery.
Background technique
Rotary component is generally all arranged on the machinery, some machinery is only permitted rotary component and is rotated towards a direction, mustn't rotate in the opposite direction by rotary component, in order to prevent the opposite spin of machinery rotary component, in the prior art, between the axle on rotary component and the fixed component, be connected with the rotation non-return device of click structure.When the rotation non-return device of click structure is rotated in the forward at work, ratchet bump ratchet, noise is bigger, the peace and quiet of influence of noise working environment, noise also is a kind of pollution to environment.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, to propose a kind of muting rotation non-return device.
The utility model is realized with the following method.
The rotation non-return device has disc check wheel, there is axis hole at the center of check wheel, the axis of check wheel and check wheel central shaft hole is on same straight line, be evenly equipped with the dihedral angle v notch v that two～20 angles are 100 degree on the circumference of check wheel, the rib of breach dihedral angle parallels with the axis of check wheel, the dihedral angle of breach has a bigger face and a less face, the bigger face of dihedral angle and less face and check wheel outer peripheral surface have crossing line respectively, distance between the line that the rib of dihedral angle and the face of dihedral angle and check wheel outer peripheral surface intersect is the length of dihedral angle face, the length of big face is two～four times of less face length degree in the dihedral angle, the face that the rib by dihedral angle and the plane of check wheel axis and dihedral angle are bigger is perpendicular, on the less face circular hole perpendicular with this face arranged in the dihedral angle, helical spring is arranged at the bottom of the hole, be connected with ejector pin on the helical spring, in the dihedral angle v notch v, cylindrical roller is arranged, the axis of the axis of cylindrical roller and check wheel is on same straight line, the diameter of cylindrical roller be in the dihedral angle less face length degree 60%～93%, there is the toroidal ring piece shape door both sides of check wheel.Dihedral angle v notch v number on the circumference of check wheel is relevant with load with the diameter of check wheel, usually is that the diameter and the big more dihedral angle v notch v number of load of check wheel is many more.
During use, the utility model is installed between the rotary component and fixed component of the machinery of mustn't rotary component rotating in the opposite direction, during installation, the check wheel is installed in the bearing housing of rotary component, cylindrical roller is between the inner circumference of breach on the check wheel and bearing housing, and the axle of rotary component is installed on the axis hole of check wheel with key.Owing to be evenly equipped with the dihedral angle that angle is 100 degree on the check wheel circumference, the dihedral angle of breach has a bigger face and a less face, so it is planes that the inner circumference of dihedral angle v notch v and bearing housing is formed two faces, a face is the approximate tri-prism of cylndrical surface, it is the obtuse angle of 100 degree that tri-prism has a dihedral angle, a less acute angle and a bigger acute angle, cylindrical roller is in tri-prism, when the ring overcoat of rotation non-return device during towards the rotation of the direction of bigger acute angle, cylindrical roller is subjected to the component of centrifugal direction, the unfettered rotation of cylindrical roller makes the rotation of ring overcoat; When the ring overcoat of rotation non-return device when the rotation of the direction of less acute angle is counterrotating, cylindrical roller is subjected to the component of centripetal direction, cylindrical roller is pushed in the less acute angle, tightly be pressed in the less acute angle in the tri-prism, cylindrical roller is tied and can not rotates, and the ring overcoat can not rotate.Ring overcoat of the present utility model can only be towards a direction rotation with respect to check wheel, can not counterrotating, play the effect of rotation non-return device.The cylindrical roller that the utility model plays non-return effect at work rotates, and does not have impact noise, and the working environment peace and quiet do not have noise pollution.
Below in conjunction with accompanying drawing, the utility model is further described.
