Abstract
The invention discloses a large-diameter flexible pin tooth driving device comprising a gear and a large-diameter pin wheel meshed with the gear. The driving device also comprises a swing rod, a push rod mechanism acted on the swing rod and a gear seat for fixing the gear, wherein one end of the swing rod is connected with the gear seat; the other end of the swing rod is articulated with a swing rod seat; the push rod mechanism consists of a push rod and a force applied member; and one end of the push rod is connected with the swing rod and the other end of the push rod is connected with the force applied member, so that force forced by the swing rod always keeps favorable mesh between the gear and the large-diameter pin wheel. The invention can ensure that the gear does following motion in the radial direction along with the large-diameter pin wheel and keep the meshed center distance unchanged.
Description
Technical field
The present invention relates to a kind of large-diameter flexible pin tooth driving device.
Background technique
In some low-speed heave-load transmissions, adopt big pin wheel and gear ratio more favourable economically with gearwheel and gear transmission.At first the manufacture cost of gearwheel is the several times of big pin wheel, if gearwheel tooth has been broken then, then whole gearwheel will be scrapped; And big pin wheel one of them sell bad, only need this pin has been replaced just.All there are certain problem in big pin wheel and gear drive: particularly when the big pin wheel diameter is very big, for the ease of transportation, generally it is designed to the structure of several combinations, and then a pin wheel is dressed up with the structural group of these several combinations in the scene.But in transportation and assembling process, several combined mechanisms of this of pin wheel can deform, and add the foozle of pin wheel itself, and the pin wheel out of roundness after the assembling is bigger, and possible shape is not accurate.Obviously, big pin wheel and gear transmission its accuracy of mesh under the situation that centre distance is fixed is unwarrantable.For example in the place of pin wheel " protruding ", pin possibly snap in the teeth groove and roll; And in the place of pin wheel " recessed ", pin is easy to just from teeth groove, skid off and, and pin wheel and gear can not well mesh.
Summary of the invention
The purpose of this invention is to provide a kind of large-diameter flexible pin tooth driving device that can make big pin wheel and gear remain the best accuracy of mesh.
This large-diameter flexible pin tooth driving device provided by the invention; Comprise gear and the major diameter pin wheel that is engaged with; Comprise that also a fork, one act on the pinion stand of the transfer bar mechanism of fork, a fixing said gear, wherein an end of fork is connected with pinion stand, and the other end and swing rod are hinged; Said transfer bar mechanism is made up of push rod and force application component; One end of push rod is connected with fork, and the other end is connected with force application component, and the power that fork is received can keep gear and major diameter pin wheel good engagement all the time.
Said force application component can adopt spring, and spring one end is connected with push rod, and the other end connects spring seat.Said push rod adopts two joints, connects with nut between two joints, is used to regulate elastic force.
Said force application component also can adopt oil hydraulic cylinder or pneumatic cylinder, with the piston rod of oil hydraulic cylinder or pneumatic cylinder as push rod.
The invention has the beneficial effects as follows: perhaps regulate the pressure in pneumatic cylinder and the oil hydraulic cylinder through Regulation spring pressure; Make push rod all the time with a suitable fork of trying hard to recommend; Fork and then pressing pinion stand; Make the gear shoulder that is installed on the pinion stand paste the pin wheel clamping plate on both sides up and down all the time, thereby make gear, keep meshed center distance constant along with the major diameter pin wheel is radially being done " servo-actuated " motion.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention 1;
Fig. 2 is the structural representation of the embodiment of the invention 2.
Embodiment
Mode of execution one:
As can beappreciated from fig. 1; This large-diameter flexible pin tooth driving device of the present invention comprises a gear 3, major diameter pin wheel 9,10, one pinion stands 2 of fixed mounting base; Its middle gear 3 is installed in the pinion stand 2 vertically; Major diameter pin wheel 9 is installed on the fixed mounting base 10, and gear 3 is meshed with major diameter pin wheel 9, and the shoulder of gear 3 abuts against on the clamping plate on major diameter pin wheel both sides about in the of 9.Be connected with a fork 1 on the pinion stand 2; This fork is connected with a pushing mechanism A; This pushing mechanism A is made up of force application component B and push rod 5, and an end of push rod 5 is connected with force application component B, and the other end is connected with fork 1; Make gear 3 along with major diameter pin wheel 9 is radially being done " servo-actuated " motion for all the time suitable power of fork, keep meshed center distance constant.What as can beappreciated from fig. 1 force application component adopted in this mode of execution is spring 4, and this spring is positioned at spring seat 11, and an end of spring 4 is connected with push rod 5.The other end is connected with the bottom of spring seat 11.Push rod 5 can be designed to two joints, connects with nut 6 adjustable grounds between two joints, and then makes spring pressure adjusted.
Mode of execution two:
Fig. 2 has reacted the concrete structure of another embodiment of the present invention; What this mode of execution was different from that embodiment's 1 part mainly is that force application component B adopts is pneumatic cylinder or oil hydraulic cylinder 7; Piston rod with this cylinder is connected with fork 1 as push rod 5, regulates the pressure in pneumatic cylinder or the oil hydraulic cylinder 7, makes push rod 5 all the time with a suitable fork 1 of trying hard to recommend; Fork 1 and then pressing pinion stand; Make the gear shoulder that is installed on the pinion stand paste the pin wheel clamping plate on both sides up and down all the time, thereby make gear, keep meshed center distance constant along with the major diameter pin wheel is radially being done " servo-actuated " motion.
