Abstract
The utility model relates to a drive disk assembly, especially a lift drive screw. Be equipped with the screw thread on the transmission shaft, the setting of the same interval of screw thread is spiral formal distribution on the surface of transmission shaft, forms a stabilisation groove between the screw thread, extends an inclined plane to the stabilisation groove direction respectively in the both sides of screw thread, forms a stable transmission 's thread, the installation department be an installation axle, at the epaxial installation thread that is equipped with of installation, set up the straight flute on the installation thread, form spacing thread. The inclined plane of screw thread and slope is utilized to above -mentioned structure, forms a cross -section and be trapezoidal stabilisation groove, and with stable transmission 's thread cooperation, in the time of the pivoted, the ductility of slope can not make the transmission block, and rotational stabilization is accurate moreover, and at the installation department, has not only adopted trapezoidal installation thread, has the extrusion space, install more firmly, sets up the straight flute moreover and form special limit structure on the installation thread, further the firm degree installed of improvement.
Description
Technical field
This utility model relates to a kind of drive disk assembly, especially a kind of lifting drive screw.
Background technology
Power transmission shaft is a high rotating speed, the rotary body of few supporting, and therefore its dynamic balancing is
Vital.General power transmission shaft will carry out dynamic balance running before dispatching from the factory, and flat
Adjusted on weighing apparatus machine.Drive screw on market exists thread rotation to be blocked, transmission
Not smooth, when quickly running, transmission location is inaccurate and transmission is unstable, and screw rod is installed loosely
Gu, cause screw rod in problems such as transmission process inefficacies.
Utility model content
The purpose of this utility model is, it is provided that a kind of stable transmission, the liter firmly installed
Fall drive screw.
This utility model solves its technical problem and be the technical scheme is that a kind of lifting
Drive screw, including driving section and installation portion, driving section is wholely set with installation portion, its
The driving section being characterised by described is power transmission shaft, is provided with screw thread, screw thread phase on power transmission shaft
With the surface being arranged on power transmission shaft of spacing, helically formal distribution, between the threads shape
Become a gutter, extend an inclined-plane in the both sides of screw thread respectively to gutter direction,
Forming the thread of a stable drive, described installation portion is one and installs axle, is installing
Axle is provided with installation thread, offers straight trough installing, form spacing thread on thread.
Of the present utility model it is further arranged to: described installation thread cross section is trapezoidal.
Of the present utility model it is further arranged to: described straight trough is V-type straight trough, uniformly
It is distributed on installation thread, forms the straight trough group of annular.
Said structure utilizes the inclined-plane of screw thread and inclination, and it is trapezoidal steady for forming cross section
Determine groove, coordinate with the thread of stable drive, rotating when, the ductility of inclination,
Transmission will not be made to block, and slow-roll stabilization is accurate, and at installation portion, not use only
Trapezoidal installation thread, has extruding space, installs more firm, and is installing on thread
Straight trough is set and forms special position limiting structure, improve the stable degree installed further.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present embodiment；
Fig. 2 is the partial enlarged drawing of the present embodiment.
Detailed description of the invention
Understanding with reference to Fig. 1-2, this utility model one lifting drive screw, including transmission
Portion 1 and installation portion 2, driving section 1 is wholely set with installation portion 2, described driving section 1
For power transmission shaft, power transmission shaft is provided with screw thread 11, screw thread 11 uniform distances be arranged on biography
The surface of moving axis, helically formal distribution, form a gutter 12 between screw thread 11,
Extend an inclined-plane 13 in the both sides of screw thread 11 respectively to gutter 12 direction, form one
The thread of individual stable drive, described installation portion 2 is one and installs axle, on the mounting shaft
It is provided with installation thread 21, offers straight trough 211 installing on thread 21, form spacing thread,
The straight trough 211 that described installation thread 21 cross section is trapezoidal, described is V-type straight trough, all
Even being distributed in is installed on thread 21, forms the straight trough group of annular.
Obviously, above-described embodiment is only used to done citing is clearly described, and also
The non-restriction to embodiment.To those of ordinary skill in the art, state upper
Can also make other changes in different forms on the basis of bright.Here without also
Cannot all of embodiment be given exhaustive.And thus extended out obvious.
