Abstract
The utility model discloses a novel swinging screw elevator, comprising a transmission nut (3), a screw and a rotating member (6). The transmission nut (3) is respectively connected with the screw and the rotating member (6). The utility model is characterized in that the split-type transmission nut (3) is connected into a whole body through threads (4) and is fixed through a screw (5), and the transmission nut (3) is connected with the rotating member (6) through drum teeth (7). The utility model has the advantages that the structure is simple, the cost is low, the transmission clearance between the transmission nut and the screw is adjustable, a certain radial displacement is allowed at the end of the screw, additional load perpendicular to the lifting direction can be effectively avoided, the required machining accuracy of the transmission nut and the required installation accuracy of the elevator are reduced relatively, the service life of the elevator is prolonged and the application scope of the elevator is widened.
Description
Technical field
The utility model belongs to mechanical field, is specifically related to novel swing screw-threaded shaft elevator.
Background technology
At present domestic common screw-threaded shaft elevator exists: 1, driving nut and lead screw transmission gap can not be adjusted, and cause drive gap to be difficult to control; 2, common screw-threaded shaft elevator can only be realized the transmission of mono-straight line, and can not there be radial displacement the end of leading screw, can not bear usually from the increment load perpendicular to the lifting direction; 3, common screw-threaded shaft elevator requires highly to the working accuracy of driving nut and leading screw and setting accuracy, can only use under the straight line transmission situation consistent with the lifting direction.
Summary of the invention
The purpose of this utility model is: design a kind of novel swing screw-threaded shaft elevator, driving nut and leading screw gap can be adjusted, allow the leading screw end that certain radial displacement is arranged, automatically regulating straight line transmission direction, can avoid effectively from increment load, prolong the service life of screw-threaded shaft elevator perpendicular to the lifting direction.
Technical solution of the present utility model is: comprise driving nut, screw mandrel and revolving meber, driving nut connects screw mandrel and revolving meber respectively, it is characterized in that: split type driving nut becomes whole by thread connection, and by screw retention, driving nut connects revolving meber by the drum type tooth.
In the novel swing screw lift of the present utility model, the two ends of driving nut are supported by globe bearing, and are sealed by V-shaped seal ring.
The utlity model has following advantage: 1, driving nut is split type, and two splits by screw retention, realize the adjustment of the drive gap of driving nut and leading screw by thread connection; 2, adopted crowned teeth to connect between revolving meber and the driving nut, realized that driving nut can be the circular cone swing in wraparound commentaries on classics center in 2 ° of scopes, make leading screw its end when straight-line motion also certain radial displacement can be arranged, can bear effectively from extra increment load perpendicular to the lifting direction; 3, elevator structure is simple, has reduced driving nut working accuracy and the requirement of elevator setting accuracy, has prolonged the service life of screw-threaded shaft elevator, has enlarged Applicable scope.
