Abstract
A C-arm track rotation transmission mechanism for an electric C-arm machine belongs to the technical field of medical instruments and structurally comprises a C-arm, a support arm, a worm speed reducing motor, a belt pulley A, a belt pulley B, a belt pulley C, a guide wheel, a synchronous belt A, a synchronous belt B, a shaft and the like. The C-arm track rotation transmission mechanism is technically characterized in that the C-arm and the support arm form a rotation sliding pair, the support arm is fixedly connected with the worm speed reducing motor, and the belt pulley A is fixedly connected to an output shaft of the speed reducing motor. The shaft and the support arm form a rotating pair, the guide wheel and the support arm form another rotating pair, the belt pulley B and the belt pulley C are fixedly connected to the shaft, two ends of the synchronous belt B are respectively wound around the guide wheel to be fixedly connected to two ends of the C-arm, the belt pulley A, the belt pulley B and the synchronous belt A realize primary transmission, and the C-arm, the belt pulley C and the synchronous belt B realize secondary transmission. A transmission path sequentially runs from the worm speed reducing motor via the primary transmission, the second transmission so that the C-arm can rotate along a C-arm track. The C-arm track rotation transmission mechanism for the electric C-arm machine has the advantages that the C-arm track rotation transmission mechanism is simple in processing and assembly and low in manufacturing cost, and the width of the support arm is small, so that the support arm and the integral machine coordinate well and are simple and attractive.
Description
Technical field
The invention belongs to technical field of medical instruments.
Background technique
The existing C orbit arm rotating actuator that is used for electronic C arm machine; Probably there are two kinds; A kind of of patent ZL200820041173.8 (full-automatic C type arm X-ray machine C type arm twin shaft is to rotational structure), drive C arm and x-ray source assembly through motor-Worm and Worm Gear Driving-synchronous pulley transmission; Another kind of as patent ZL200820238187.9 (a kind of C arm in orbit both can electronic also manual medical x-ray machine) is said to be through worm speed-down motor-synchronous pulley transmission drive C arm and x-ray source assembly; The former advantage is a compact structure; The support arm width is little, and support arm is succinct, attractive in appearance.But Worm and Worm Gear Driving is to processing and assemble adjustment requirement height, and rigger's technical merit is required height, and therefore total manufacture cost standard size retarder cost than the production in enormous quantities of purchase specialized factory on the contrary is big; The latter uses the master worm retarder, and is low to processing and matching requirements, requires low to rigger's technical merit; Thereby cost is low; But because the width dimensions of retarder is bigger than independent worm gear width dimensions, so the total transverse dimension of driving mechanism is big, causes the support arm width dimensions big; Perhaps a side of support arm is a bulk of because of the dress retarder bloats, and support arm and complete machine are inharmonious, wordy, not attractive in appearance.
Summary of the invention
Goal of the invention of the present invention is: for the defective that overcomes above-mentioned existence and make full use of its advantage, design a kind of C orbit arm rotating actuator that is used for electronic C arm machine, not only processing and assembling is simple, and the support arm width is little.
The technical solution adopted for the present invention to solve the technical problems is: its structure by C arm, support arm, worm speed-down motor, belt wheel A, belt wheel B, belt wheel C, guide wheel, synchronously be with A, be with parts such as B, axle to form synchronously; Its technical characteristics is: it is secondary that C arm and support arm are formed rotational slide; The support arm worm speed-down motor that is connected, belt wheel A is fixed on the output shaft of reducing motor.Axle, guide wheel are formed revolute with support arm respectively, and belt wheel B, belt wheel C are fixed on axle, are with the B two ends to walk around guide wheel respectively synchronously and are fixed in C arm two ends, and belt wheel A, belt wheel B form first order transmission with being with A synchronously, C arm, belt wheel C and band B composition second level transmission synchronously.Drive path is: worm speed-down motor → first order transmission → second level transmission → C arm rotates along the C orbit arm.Because first order transmission is arranged, make the centre of the inclined to one side support arm in position of worm speed-down motor, the width dimensions of support arm is little.
The invention has the beneficial effects as follows: not only processing and assembling is simple, and is low to the requirement of assembler's technical merit, low cost of manufacture, and also the support arm width dimensions is little, makes support arm and complete machine coordination, succinct, attractive in appearance.
