Abstract
A pulley angle regulator comprises a pulley, a bearing rotating shaft and bearing supports. The pulley is connected to the bearing rotating shaft through spherical roller bearings. The spherical roller bearings are disposed at two ends of the bearing rotating shaft, respectively. The spherical roller bearings are mounted on the bearing supports through eccentric shaft sleeves. A spherical washer is disposed at one end, far away from the pulley, of each eccentric shaft sleeve. The spherical washers and the spherical roller bearings co-act to regulate the angle of the bearing rotating shaft; the spherical washers are fixedly held through locknuts penetrating the two ends of the bearing rotating shaft. The bearing rotating shaft is regulated through the spherical roller bearings, so that large deviation of the angle is avoided; the bearings limit the range of angular regulation, and bearings can co-act with the spherical washers to ensure that the bearing rotating shaft can be fixed in time after regulation and that the service life of the bearing rotating shaft is protected from influence caused by the bearing rotating shaft suffering radial shear.
Description
Technical field
The present invention relates to a kind of belt pulley auxiliary device, especially relate to a kind of belt pulley angular adjustment apparatus.
Background technique
Belt transmission is a kind of conventional kind of drive, in belt transmission process, because belt process easily causes angular deflection, need to adjust angle, and to the often bad assurance of the angular adjustment of belt pulley, easily cause more large deviation, and at least one small angle of the augular offset of belt pulley own, adjust the excessive transmission use that affects, do not adjust and can affect belt life, and existing adjustment mode is difficult to satisfy condition.
Summary of the invention
The object of the invention is the problem easily causing a deviation for solving belt pulley angular adjustment, a kind of belt pulley angular adjustment apparatus is provided, device in the present invention adopts spherical bearing to adjust carrying rotating shaft by adjustment, thereby ensure that angle there will not be large deviation, because carrier bearing has limited the scope of angular adjustment, coordinate spherical washer simultaneously, after can ensureing to adjust, axle can be fixed in time and avoid axle to be subject to radially shear force simultaneously, and affect life-span of axle, and lock and can ensure that axle can not become flexible and reappear deviation by locking nut, ensure to adjust the stability of effect.
The present invention is the deficiency solving the problems of the technologies described above, and the technological scheme adopting is:
A kind of belt pulley angular adjustment apparatus, comprise a belt pulley, carrying rotating shaft and bearing support, belt pulley is connected in carrying rotating shaft by spheric roller bearing, the two ends of carrying rotating shaft are separately installed with spherical bearing, spherical bearing is arranged on bearing support by excentric sleeve, excentric sleeve is away from being also provided with spherical washer on one end of belt pulley, and spherical washer coordinates the angle of spherical bearing adjustment carrying rotating shaft and fixes by the locking nut compression spherical washer being located on carrying rotating shaft two ends.
Described spheric roller bearing is provided with between two and two spheric roller bearings and is provided with axle sleeve.
Described excentric sleeve carries rotating shaft being bolted on bearing support radially by edge.
The invention has the beneficial effects as follows: the device in the present invention adopts spherical bearing to adjust carrying rotating shaft by adjustment, thereby ensure that angle there will not be large deviation, because carrier bearing has limited the scope of angular adjustment, coordinate spherical washer simultaneously, after can ensureing to adjust, axle can be fixed in time and avoid axle to be subject to radially shear force simultaneously, and affect life-span of axle, and lock by locking nut and can ensure that axle can not become flexible and reappear deviation, ensure to adjust the stability of effect.
1, reach relies on left and right spherical bearing to support, and spherical bearing can be delivered interior carrying at 15 degree, can ensure that reach 15 degree tilt to install.
2, the reach right locking nut that keeps left is fixed, and the inclination of locking nut is installed and relied on spherical washer to adapt to different angles.
3, the packing ring supporting surface of excentric sleeve is sphere machined grooves, and spherical washer angle adapts to mutually, ensures the installation of spherical washer.
