Abstract
The utility model discloses an electric motor displacement transducer with axial direction double-reed center-return, which relates to a control mechanism used for a computer speed regulator of a water and electricity system, in particular to an electric motor displacement transducer with automatic oil-free center-return. The utility model mainly comprises an outer shell, and a drive shaft, as well as an output shaft placed in the outer shell cavity, the drive shaft upper end is connected with an actuating motor or a stepping motor, and the output lower end is connected with the computer speed regulator; the output shaft outer-ring sheathed on the outside of a bearing ball nut is arranged with an upper reset spring and a lower reset spring placed in axial direction and supported by a support seat, the upper ends of the upper reset spring and the lower reset spring are separately stuck on relevant positions near the shaft, an output shaft guide key is arranged between the bearing ball nut and the outer shell, and a fixed nut and a limit nut of the output shaft are positioned on the support seat lower end. The electric motor displacement transducer can adapt to speed regulators with various capacities, which can realize automatic center-return when loosing the electricity with simple and reliable manual operation device. The utility model has very broad application prospects in the water and electricity system.
Description
Technical field
The utility model relates to the control mechanism that the hydroelectric system microcomputer governor is used, especially a kind of displacement motor transducer that does not have in oil can be automatically multiple.
Background technique
The microcomputer governor of the current use of hydroelectric power system has two kinds of control modes: a kind of is electro-control converter control, and the characteristics of this mode are to assign to change the magnification factor of system by electrical part, thereby can adapt to the speed regulator of various capacity; But this control mode can not guarantee the servomotor invariant position when system blackout, and its hand-operating device complexity.Another kind is the control of step motor drive step-by-step cylinder formula electro-control converter, and it also can reach aforementioned effect, but when system blackout, during it can not be answered, if increase wire rope and feedback linkage etc., though can guarantee the servomotor invariant position, therefore mechanism will become very complicated.
Summary of the invention
The purpose of this utility model provides a kind of nothing oil displacement motor transducer of multiple middle function automatically that has, it can adapt to the speed regulator of various capacity, can guarantee speed regulator reliability of operation and stability, in particularly answering automatically when system's power down, in addition, also has hand-operating device.
The purpose of this utility model is achieved in that the multiple middle displacement motor transducer of axial two-man act is mainly by shell and the transmission shaft that places its cavity, output shaft is formed, transmission shaft and output shaft are the axle on the same axis, the transmission shaft upper end that is cooperatively interacted by ball screw and ball nut is connected with actuating motor or stepper motor, the output shaft lower end is connected with microcomputer governor, its specialization is: the periphery that is enclosed within the outer output shaft of ball nut, be provided with the upper reset spring and the following Returnning spring of the axial placement of supporting by supporting base, on, the upper end of following Returnning spring is stuck on the relevant position of next to axis, between output shaft and shell, be provided with the output shaft feather key, the lower end that the fixedly round nut of output shaft and stop nut are positioned at supporting base.
The transmission shaft upper end of described displacement motor transducer is provided with large and small bevel gear and handle cooperates the hand-operating device of forming, and large umbrella gear is arranged at outside the coupling band, and its lower end is by the adjustment nut support and the location that are fixed on the coupling band.
Described upper and lower Returnning spring is a cylinder-shaped compression spring.
Displacement motor transducer of the present utility model, combine electrohydraulic control control features in the prior art, and on this basis the motor driven ball screws pair has been increased axial spring structure, make it to become a kind of displacement motor transducer of brand-new, no fluid, this displacement motor transducer has overcome hydraulic servo device and has existed noise, leakage of oil to reach deficiencies such as dirt sensitivities in the fluid, and this displacement motor transducer can adapt to the speed regulator of various capacity.In particularly answering automatically when system's dead electricity, the hand-operating device of setting is simple and reliable to be its outstanding advantage.Displacement motor transducer of the present utility model is very wide in the hydroelectric system application prospect.
Description of drawings
Accompanying drawing 1 is the multiple middle displacement motor converter structure schematic representation of axial two-man act.
Accompanying drawing acceptance of the bid keep the score state as follows: 1---actuating motor or stepper motor; 2---coupling band; 3---ball screw; 4---ball nut; 5---output shaft; 6---round nut; 7 supporting bases one by one; 8---go up reset spring; 9---following reset spring; 10---stop nut; 11---the lower limit cover; 12---feather key; 13---adjust nut; 14---large umbrella gear; 15---small umbrella gear; 16---handwheel; 17---the nut baffle ring.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.As shown in the figure, the driving procedural order of displacement motor transducer of the present utility model is: servo microcomputer motor or stepper motor 1 make ball screw 3 rotations by coupling band 2, when supposing to turn clockwise, the output shaft 5 that is connected with ball nut 4 move upward (because of ball nut is subjected to feather key constraint can only straight-line displacement), the round nut 6 on the output shaft 5 drives supporting bases 7 compression upper reset springs 8; When motor power disappeared, output shaft 5 was got back to the origin-location under the reaction force (anti-compressive force) of upper reset spring 8 drives.The home position that origin-location described here promptly is meant, point midway, dead-center position, or claim the equinoctial point position.Automatically be because the ball screw auxiliary driving does not have self-locking performance in multiple, when ball nut 4 is promoted by the reaction force of upper reset spring 8, will make the leading screw rotation, drive the output shaft 5 that is connected one with it and produce, make output shaft 5 get back to original position to bottom offset.In like manner, when actuating motor or stepper motor were rotated counterclockwise, output shaft 5 was to bottom offset, and ball nut 4 drives nut baffle ring 17, feather key 12 reset spring 9 under lower compression, after the motor dead electricity, under the reset spring reaction force drives down, got back to the origin-location again.This displacement motor transducer output shaft reference point location and displacement amount can be regulated by stop nut 10, adjust very conveniently, and servo-actuated precision height is exported in displacement.
