Abstract
The utility model relates to the technical field of a speed changer in a machine, which is designed for reducing abrasion. The three-star gear speed changer has a central gear which is outwards engaged with three equispaced planet gears; the planet gears are engaged with the ring teeth of an inner ring of an inside and outside work applying wheel. The utility model is characterized in that a plug head cover with a shaft hole is fixedly connected with the lateral face of the work applying wheel; the surface of the end head cover is provided with a lube filling hole; the lube filling hole is poured with lube and is sealed by a sealing member; the sealing member is arranged at the position of a sealing surface needing contact. The utility model has the advantage of having simple structure, reducing abrasion, and extending service life. The utility model is suitable for being popularizing on speed changers.
Description
The utility model relates to speed changer technical field in a kind of machinery.
Speed changer is a common components in the mechanical device, as China Patent No. is that 91228067.0 bicycle use stepless speed variator just adopts speed change drive mechanism like this, in the driven wheel outer gearing three uniform planet wheels are arranged, planet wheel is meshed with the inner circular tooth of friction wheel again, there is a rotational speed governor at the friction wheel edge, adjust the rotating speed of controller control friction wheel by handle, thereby reach the speed change purpose.Its shortcoming is: do not have oil-filling device, gear engagement lacks oil lubricating, thereby causes frictional force big, easily blocks and gets rusty, requires great effort.
The purpose of this utility model is to provide, and thereby a kind of oil-filling device simple in structure makes that engaging gear is not easy to wear, long service life, tumbler gear speed changer that power loss is few.
The technical solution of the utility model is to realize like this.This tumbler gear speed changer has a central gear, three uniform planetary pinions of outer gearing, planetary pinion is meshed with the interior ring ring tooth of acting wheel inside and outside again, it is characterized in that plug lid in tape spool hole fixedlys connected with the wheel side that does work, and the surface has lubricating oil inlet, with the Sealing sealing, Sealing is equipped with at required contact seal face place behind the interior notes lubricant oil.
Above-mentioned acting wheel can be made belt pulley or the gear of outer shroud tooth is arranged; Above-mentioned central gear can be made driving wheel can make driven wheel again.
This tumbler gear speed changer is provided with oil-filling device simple in structure in the acting wheel, can reduce the engaging gear wearing and tearing, can strengthen lubrication again, reduce consumed power, increase the service life, and this speed changer acting wheel both can be designed to belt pulley, and can make driving gear again and make things convenient for the user, central gear can be made driving wheel or driven wheel, thus the stepless change of the speed of realization two-phase.
Description of drawings:
Fig. 1. tumbler gear speed changer structure schematic diagram;
Fig. 2. tumbler gear speed changer front appearance figure.
Below in conjunction with description of drawings embodiment of the present utility model is further described.
As shown in the figure, this speed changer has a central gear 2, three uniform planetary pinions 1 of outer gearing, planetary pinion is meshed with the interior ring ring tooth of acting wheel 3 inside and outside again, the plug lid 4 in tape spool hole is lived with screw 6, spacers with the acting wheel side respectively, and the surface has a lubricating oil inlet 5, behind the interior injection lubricant oil, with the Sealing sealing, need contact seal face place Sealing to be housed in case leak-stopping oil at all.This acting wheel can be made belt pulley, and the gear of ring ring tooth is so that input output power over can making again.Central gear can be made driving wheel or driven wheel, and inside and outside accordingly acting wheel is made follower or driving wheel.
