Description
Technical field
The present invention relates to a kind of gear case, particularly relate to the blocking rotation gear case for lifting screw.
Background technology
For the full depth tooth roller box of lifting screw, screw mandrel wherein and feed screw nut in load-bearing operational process to two extreme positions time, screw pair easily occurs stuck, produces the situation of stall.Gear case, once situation that is stuck, stall, will cause great damage to motor, screw pair or other drive disk assemblies, therefore greatly can reduce the service life of full depth tooth roller box.
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, aim to provide and there is protection mechanism, the blocking rotation gear case that the situations such as stuck, stall occur can be prevented.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals:
Blocking rotation gear case, comprises casing, is provided with driving gear, performs gear and micro-switch in casing, and driving gear, by reducing gear and execution gears meshing, performs the action of gear drive micro-switch.Driving gear is connected with the screw mandrel of casing outside, driving gear is driven to rotate by screw mandrel, execution gear is given Movement transmit again through reducing gear, to be coordinated with the switch contact of micro-switch by the groove performing gear outer wall and realize opening or closing of micro-switch, thus control the break-make of motor, reach spacing object, actv. prevents the appearance of the situations such as 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 blocking rotation gear case outside.
As preferably, reducing gear is dual gear.Dual gear stable transmission, driving efficiency are high, and long service life.
As preferably, the quantity of reducing gear is A, and A >=1.The quantity of reducing gear can select different quantity according to the demand of reality, to reach different slowing effect.
As preferably, execution gear is internally toothed annulus, performs gear outer and is provided with groove, and groove is distributed on and performs gear outer.
As preferably, micro-switch is provided with switch contact, and switch contact contacts with the outer performing gear.Switch between the groove of switch contact on the outer wall performing gear and outer wall, realize micro-switch action, thus control the break-make of motor by micro-switch.
As preferably, the quantity of micro-switch is two.
As preferably, the diameter performing gear is greater than the diameter of driving gear.Driving gear can be positioned over the inside performing gear, thus saves the volume of blocking rotation gear case.
According to technical scheme of the present invention, blocking rotation gear case achieve when feed screw nut run to screw mandrel two extreme positions and close to stall time, by the combination of multi-stage gear, and the cooperation of micro-switch, reach cut-out motor power, make the object that motor shuts down, thus prevent the appearance of stall situation.Therefore; blocking rotation gear case is reasonably combined by gear mechanism; eliminate the problem of two extreme position screw mandrel stalls; simultaneously Ye Shi mechanism runs to two extreme positions and can steadily stop; eliminate the impact of stall to screw mandrel and main frame; protect motor, protect screw mandrel, thus substantially prolongs the service life of main frame, improve the reliability of mechanism.In addition, blocking rotation gear case have employed internally toothed annulus as execution gear, makes driving gear can be positioned over the inside performing gear, and then has greatly saved the volume of casing.
Accompanying drawing explanation
Fig. 1 is the structural representation of blocking rotation gear case of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail.
Embodiment 1
Blocking rotation gear case, comprises casing 1, is provided with driving gear 2, performs gear 3 and micro-switch 4 in casing 1, and driving gear 2 is engaged with execution gear 3 by reducing gear 5, performs gear 3 and drives micro-switch 4 action.
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 axis hole, when outside screw mandrel rotates, driving gear 2 can be driven to rotate.Driving gear 2 drives reducing gear 5 to rotate by teeth.
Reducing gear 5 is dual gear.Dual gear is by connecting a gear coaxial combination together, and synchronous axial system or stopping.
The quantity of reducing gear 5 is A, and A >=1.
Performing gear 3 is internally toothed annulus, performs gear 3 outer and is provided with groove 6, and groove 6 is distributed on and performs gear 3 outer.
Micro-switch 4 is provided with switch contact 7, and switch contact 7 contacts with the outer performing gear 3.
The quantity of micro-switch 4 is two.
The diameter performing gear 3 is greater than the diameter of driving gear 2.Driving gear 2 is installed on the volume performing and can save casing 1 in gear 3, also saves production cost simultaneously, improves the cost performance of blocking rotation gear case.
After blocking rotation gear case has been assembled, when the nut of casing 1 outside run to screw mandrel two extreme positions and close to stall time, because motor can not stop automatically, so screw mandrel and nut can synchronous axial system.Therefore, the screw mandrel being inserted in driving gear 2 axis hole position can drive driving gear 2 to rotate, and driving gear 2 drives reducing gear 5 to rotate by the teeth of outer.Reducing gear 5 by the teeth of outer and the interior meshing along teeth of execution gear 3, thus drives execution gear 3 to rotate.Perform gear 3 when rotating, and the switch contact 7 performing gear 3 wall contacts will switch at groove 6 and performing between gear 3 outer wall, thus the action of driving micro-switch 4.Micro-switch 4 controls the break-make of motor, thus when realizing blocking rotation gear case stall, motor power-off, prevents the damage of blocking rotation gear case.Therefore, be greatly improved the service life of blocking rotation gear case.
In addition, blocking rotation gear case can also set the anglec of rotation, the number of turns of screw mandrel movement length or the rotating mechanism that will control easily by the groove location adjusting internally toothed annulus outer.
In a word, the foregoing is only preferred embodiment of the present invention, all equalizations done according to the present patent application the scope of the claims change and modify, and all should belong to the covering scope of patent of the present invention.
