Speed changer to fix or stepping changes the gear drive of output shaft and input shaft velocity ratio, also known as gearbox.Speed changer is made up of driving mechanism and gear, can be made into independent gear or attaches together in same housing with driving mechanism.The large multiplex ordinary gear transmission of driving mechanism, what also have uses Planetary Gear Transmission.
Ordinary gear transmission shifting mechanism generally uses shifting slide gear and synchronizer etc., and shifting slide gear has multi-joint shifting slide gear and conjugates dividing of shifting slide gear.By three shifting slide gear speed changes, axial dimension is large; With displacement shifting slide gear speed change, compact structure, but velocity ratio change is little.Synchronizer have engagement type and friction type point.During with engagement type synchronizer, speed change should be carried out when stopping or speed discrepancy is very little; Can carry out speed change during on-stream any speed discrepancy with friction type synchronizer, but bearing capacity is little, and diaxon stringent synchronization can not be ensured.For overcoming this shortcoming, friction plate being loaded onto by engagement type synchronizer, engaging again after first follower being taken to synchronous speed by friction plate during speed change.Planetary Gear Transmission speed changer available brake device controls speed change.Speed changer be widely used in lathe, vehicle and other need on the machine of speed change.
Speed change gear in speed changer requires that conversion is brisk, the efficiency of transferring power wants high, and bearing capacity is strong, but the speed change gear quantity in current speed changer is more, combination with one another has coordinated speed change task, this spline structure is comparatively complicated, and matching requirements are high, and manufacturing costly, manufacturing cycle is long, running energy consumption is high, and the frequency producing fault in using process is high, and user cost is high.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, provides a kind of compact structure, easy to use, the integrated type speed change gear that can effectively reduce costs.
The purpose of this utility model realizes by following technical proposal: a kind of integrated type speed change gear, comprise gear, described gear axially offers splined hole, it is characterized in that, there is in the middle part of the outer circumferential face of described gear the moving tooth portion of a circle radial protrusion, what offer a loop in the middle part of the outer circumferential face in described moving tooth portion stirs groove, and the outer circumferential face of described gear has the driving cog being symmetrical in described moving tooth portion and arranging.
This integrated type speed change gear by the past stir tooth and gear is made of one formula structure, make compact structure, decrease operation, easily manufactured, effectively reduce manufacture cost, and easy to install, eliminate the medium tache of in the past stirring the transmission of cingulum moving gear body in addition, reduce power transmission loss, improve transmission efficiency.
In above-mentioned a kind of integrated type speed change gear, described moving tooth portion offers several and be uniformly distributed and the through hole axially arranged.The setting of through hole decreases deadweight, and speed change is slim and graceful, and is arranged on after in speed change gear, and the lubricant oil being positioned at this integrated type speed change gear both sides can be circulated by through hole, high lubricating effect.
In above-mentioned a kind of integrated type speed change gear, described moving tooth portion offers be positioned at through hole two ends extend out fillet.Extend out fillet and further mitigate deadweight, make lubricant oil enter through hole convenient smooth simultaneously.
In above-mentioned a kind of integrated type speed change gear, described gear offers the annular groove that twice are symmetrical in the setting of moving tooth portion, described annular groove is between the root and driving cog in moving tooth portion.Annular groove alleviates deadweight further, and facilitates the processing of driving cog, and machining accuracy is high.
In above-mentioned a kind of integrated type speed change gear, the outer end of described driving cog is provided with face, oblique angle, and described face, oblique angle makes the length of driving cog teeth be less than the length of driving cog tooth root and the angle of described face, oblique angle and horizontal plane is 45 °.Face, oblique angle be arranged so that speed change switch more smooth and easy.
In above-mentioned a kind of integrated type speed change gear, described gear offers the inner conical groove being positioned at described splined hole two ends.Inner conical groove alleviates deadweight, and makes gear easy for installation.
Compared with prior art, the compact structure of this integrated type speed change gear, easily manufactured, low cost of manufacture, and also from heavy and light, speed change is slim and graceful, and transmission efficiency is high, and self-lubricating effect is good in addition, not fragile, and long service life, user cost is low.
