Description
Technical field
The invention belongs to rack pinion technical field, driven simultaneously more particularly, to 4 points of a kind of single power source whole
Body formula rack-and-pinion lifting device.
Background technique
With the rapid development of automatic producing technology, the precision and stability of the transmission mechanism of mechanical equipment is proposed
Higher requirement, especially in weight handling field.The high stability and running precision of transmission mechanism are using automation control
Premise, also provide possibility for multiple devices linkage control.Since rack and pinion drive mechanism has, transmitting power is big, the service life
The features such as length, stable working, high reliablity, high transmission accuracy, is now widely used by various mechanical equipments, and achieving preferably makes
With effect and economic benefit.
Currently, due to the requirement and work characteristics of rack and pinion drive mechanism, now it is chiefly used in more accurate or right
In the more demanding mechanical equipment of transmission accuracy, such as lathe, 3D printer.Rack and pinion drive mechanism one in this case
As using unilateral driving, mainly play transmission effect, bearing capacity is smaller, can preferably guarantee transmission accuracy, but cannot bear compared with
Big load.For lifting device, more mature at present and application is at most hoisting mechanism, has flexible operation, holds
The characteristics of loading capability is strong, and operating condition requirement is low, wide adaptability.But it is risen because it batches the mode of steel cable by roller
Drop, belongs to Flexible Transmission, and transmission accuracy is poor, and easily generates swing in lifting or traversing process, is unsuitable for applying to essence
More demanding occasion is spent, more suspension centres synchronization lifting or traversing occasion simultaneously are such as required.In addition, there are also a kind of worm screw elevators
Structure, it has many advantages, such as, and transmission ratio is big, compact-sized and stable drive, but its transmission speed is slow, and transmission efficiency is low and to snail
The concentricity requirement of bar is higher, be not suitable for there are in lateral load or transmission process exist swing occasion.
It is existing about in rack-and-pinion lifting device technology, patent (CN 106284269) proposes a kind of rack-and-pinion
Lifting device is symmetrically arranged respectively the two-sided rack in the two sides of elevating mechanism, and each is two-sided to improve bearing capacity
The two sides of rack gear are all engaged with three pairs of transmission gears being arranged symmetrically, but each transmission gear is independently driven by a motor, altogether
6 motors are set, it is very high to the synchronously control requirement of 6 motors, it otherwise will cause the mutual containing of 6 motors, power of motor
It can increase because mutually restraining consumption, to cause power dissipation, while the stress of transmission gear and rack gear will increase, accelerate it
Abrasion reduces its service life, or even occurs to beat tooth phenomenon；Patent (CN 107366724) proposes a kind of gapless floating tooth
Rack gearing is taken turns, a motor driven intermediate gear is used, and drives two transmissions engaged simultaneously with intermediate gear
Gear is engaged with rack gear single side floating under the action of the spring, can eliminate gap, improves transmission accuracy, commonly used in high-precision
The straight line of lathe or big camber line are driven occasion, but due to its floating meshing characteristic, are only applicable to be driven, cannot bear larger load
Lotus；108163783 A of patent disclosure (notification number) CN, proposes a kind of rack-and-pinion lifting device, uses a variable-frequency electric
Machine is engaged simultaneously with a rack gear unilateral side by two transmission gears of Synchronous Transmission Component driver, lifting device can be improved
Bearing capacity, but the driving of lifting device unilateral side will cause uneven loaded situation, even if symmetrical with two sets of lifting devices simultaneously
Arrangement, can also have two nonsynchronous problems of driving motor.
