Abstract
The invention relates to a rotation-clogging preventing gear box. The rotation-clogging preventing gear box comprises a box body (1), a driving gear (2), an executing gear (3) and micro switches (4) are arranged inside the box body (1), the driving gear (2) is meshed with the executing gear (3) via a reduction gear (5), and the executing gear (3) drives the micro switches (4) to act. By the aid of the rotation-clogging preventing gear box, when a lead screw nut runs to two end positions of a lead screw and is close to rotation clogging, the purpose of cutting off a motor power supply so as to stop running of a motor is achieved via the combination of multi-stage gears and matching of the micro switches, and thereby rotation clogging is prevented. Therefore, the rotation-clogging preventing gear box eliminates the rotation clogging problem at the two end positions of the lead screw via reasonable matching of a gear mechanism, the mechanism is enabled to be stably stopped when running to the two end positions, impact to the lead screw and a host machine from rotation clogging is eliminated, the motor and the lead screw are protected, the service life of the host machine is prolonged greatly, and reliability of the mechanism is improved.
Description
Technical field
The present invention relates to a kind of gear case, relate in particular to the anti-stall gear case for lifting screw.
Background technology
The full depth tooth roller box that is used for lifting screw, during to two extreme positions, screw pair occurs stuck easily, the situation of generation stall in the load-bearing operational process for screw mandrel wherein and feed screw nut.Gear case is the situation of stuck, stall in a single day, will cause great damage to motor, screw pair or other drive disk assemblies, therefore the service life that can reduce the full depth tooth roller box greatly.
Summary of the invention
The present invention is directed to that the easy appearance that existing gear case has is stuck, stall etc. is not enough and propose, and aims to provide to have protection mechanism, can prevent the anti-stall gear case that situation such as stuck, stall occurs.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals:
Anti-stall gear case comprises casing, is provided with driving gear in the casing, carries out gear and micro-switch, and driving gear meshes with carrying out gear by reducing gear, carries out the action of gear drive micro-switch.Driving gear is connected with the screw mandrel of casing outside, driving driving gear by screw mandrel rotates, through reducing gear motion is passed to the execution gear again, cooperate opening or closing of realization micro-switch with the switch contact of micro-switch by the groove of carrying out the gear outer wall, thereby the break-make of control motor, reach spacing purpose, the appearance of situation such as that actv. has prevented is stuck, stall.
As preferably, the outer of driving gear is provided with teeth, and the center of driving gear is provided with axis hole.Driving gear is connected by teeth and reducing gear.Driving gear is connected by the screw mandrel of axis hole with anti-stall gear case outside.
As preferably, reducing gear is dual gear.The dual gear transmission is stable, driving efficiency is high, and long service life.
As preferably, the quantity of reducing gear is A, and A 〉=1.The quantity of reducing gear can be selected different quantity according to the demand of reality, to reach different deceleration effects.
As preferably, the execution gear is internally toothed annulus, carries out the gear outer and is provided with groove, and groove is distributed on carries out the gear outer.
As preferably, micro-switch is provided with switch contact, and switch contact contacts with the outer of carrying out gear.Switch contact switches between the outer wall of carrying out gear and the groove on the outer wall, realizes the micro-switch action, thereby is controlled the break-make of motor by micro-switch.
As preferably, the quantity of micro-switch is two.
As preferably, carry out the diameter of gear greater than the diameter of driving gear.Driving gear can be positioned over the inside of carrying out gear, thereby saves the volume of anti-stall gear case.
According to technical scheme of the present invention, anti-stall gear case has been realized running to two extreme positions of screw mandrel and during near stall as the feed screw nut, combination by multi-stage gear, and the cooperation of micro-switch, reach the cut-out motor power, the purpose that motor is shut down, thus prevented the appearance of stall situation.Therefore; anti-stall gear case is reasonably combined by gear mechanism; eliminated the problem of two extreme position screw mandrel stalls; simultaneously also making mechanism run to two extreme positions can steadily stop; eliminated the impact of stall to screw mandrel and main frame; protect motor, protected screw mandrel, thereby prolonged the service life of main frame greatly, improved the reliability of mechanism.In addition, anti-stall gear case has adopted internally toothed annulus as carrying out gear, makes driving gear can be positioned over the inside of carrying out gear, and then has saved the volume of casing greatly.
Description of drawings
Fig. 1 is the structural representation of the anti-stall gear case of the present invention.
The specific embodiment
Describe in further detail below in conjunction with accompanying drawing and the present invention of embodiment.
Anti-stall gear case comprises casing 1, is provided with driving gear 2 in the casing 1, carries out gear 3 and micro-switch 4, and driving gear 2 is carried out gear 3 and driven micro-switch 4 actions by reducing gear 5 and 3 engagements of execution gear.
The outer of driving gear 2 is provided with teeth, and the center of driving gear 2 is provided with axis hole.The screw mandrel of casing outside is inserted in the axis hole, when outside screw mandrel rotates, can drive driving gear 2 and rotate.Driving gear 2 drives reducing gear 5 by teeth and rotates.
Reducing gear 5 is dual gear.Dual gear is by connecting a gear coaxial combination together, and rotates synchronously or stop.
The quantity of reducing gear 5 is A, and A 〉=1.
Carrying out gear 3 is internally toothed annulus, carries out gear 3 outers and is provided with groove 6, and groove 6 is distributed on carries out gear 3 outers.
Micro-switch 4 is provided with switch contact 7, and switch contact 7 contacts with the outer of carrying out gear 3.
The quantity of micro-switch 4 is two.
Carry out the diameter of gear 3 greater than the diameter of driving gear 2.Driving gear 2 is installed on carries out the volume that can save casing 1 in the gear 3, has also saved production cost simultaneously, has improved the cost performance of anti-stall gear case.
After anti-stall gear case assembling is finished, when the nut of casing 1 outside runs to two extreme positions of screw mandrel and during near stall, because motor can not stop automatically, so screw mandrel and nut can rotate synchronously.Therefore, the screw mandrel that is inserted in driving gear 2 axis hole positions can drive driving gear 2 and rotate, and driving gear 2 drives reducing gear 5 rotations by the teeth of outer.Reducing gear 5 is passed through the teeth of outer and is carried out the interior meshing along teeth of gear 3, carries out gear 3 rotations thereby drive.When carrying out gear 3 rotations, the switch contact 7 that contacts with execution gear 3 outer walls will and be carried out between gear 3 outer walls at groove 6 and switch, thereby drives micro-switch 4 actions.The break-make of micro-switch 4 control motors, thus when realizing anti-stall gear case stall, the motor outage prevents the damage of stall gear case.Therefore, obtained the service life of anti-stall gear case improving greatly.
In addition, anti-stall gear case can also be easily set the screw mandrel movement length that will control or the anglec of rotation, the number of turns of rotating mechanism by the groove location of adjusting the internally toothed annulus outer.
In a word, the above only is preferred embodiment of the present invention, and all equalizations of doing according to the present patent application claim change and modify, and all should belong to the covering scope of patent of the present invention.
