Abstract
The utility model relates to a cross extension rod coupling which can penetrate through eyelets and be used for eyelets. The cross extension rod coupling can pass through one eyelet for transmitting the power of an input shaft (such as motor shafts) on one end of the eyelet to an output shaft (such as gear shafts) on the other end of the eyelet, simultaneously the flexible connection can be achieved, that is, the center line deviation occurred in the manufacture and the mounting by the input shaft and the output shaft can be absorbed, the operating stationarity in the transmission process can be guaranteed, and enough intensity and durable service life are provided. The cross extension rod coupling is characterized in that the coupling comprises the input shaft, the output shaft and a cross extension rod, flat squares are respectively arranged on two ends of the cross extension rod, an included angle is arranged between the flat squares on two ends, projections are respectively arranged on the end portions of the flat square, grooves to be engaged with the flat square are respectively opened on one end portion of the input shaft and the output shaft, and holes are respectively arranged on the bottom of the groove.
Description
(1) technical field
The utility model relates to the mechanical shaft joint structure of transmission, belongs to the mechanical basic part field, is specially the aperture that can pass aperture cross extension bar shaft joint.
(2) background technique
Generally speaking, the output shaft 3 of motor all will be realized by a shaft joint when input shaft 2 transferring power of working machine.And shaft joint commonly used mostly is a flange plate type, is installed on input, the output shaft, and its external diameter is than the diameter of axle greatly a lot (seeing accompanying drawing 1), and 1 is respectively left ladder axle dish, right ladder axle dish for connecting key, 4 for shaft joint telophragma, 5,6.
And the aperture that can pass aperture promptly will pass through an aperture 1 with cross extension bar shaft joint, with the power transmission of the input shaft 2 (for example motor shaft) of aperture one end to the output shaft 3 (for example gear shaft) of the aperture the other end (seeing accompanying drawing 2); It is hole that certain-length is arranged on the frame that aperture 1 can be understood as, and input shaft 2 and output shaft 3 are only slightly thin than hole diameter, and promptly the diameter of the shaft joint of Cai Yonging can not surpass the diameter of motor shaft and gear shaft, otherwise will interfere with aperture.Therefore, can't adopt conventional shaft joint herein; Conventional shaft joint needs the space of fitting operation, and in aperture, does not have the space of fitting operation, can only send into from the two ends of aperture and realize correct the installation, and existing shaft joint can't satisfy above-mentioned requirements; In addition, and all shaft joints, realize flexibly connecting, can absorb center line that input shaft and output shaft the occur deviation of beating in making, installing, guarantee the smoothness of operation in the transmission process.
(3) summary of the invention
At the problems referred to above, the utility model provides the aperture that can pass aperture with cross extension bar shaft joint, can pass through an aperture, and the power transmission of the input shaft (for example motor shaft) of aperture one end is arrived on the output shaft (for example gear shaft) of the aperture the other end; Simultaneously can realize flexibly connecting, can absorb the centerline deviation that input shaft and output shaft occur in making, installing, guarantee the smoothness of operation in the transmission process, and enough intensity and durable life-span are arranged.
Its technological scheme is such, it is characterized in that: described shaft joint is made up of input shaft, output shaft and cross extension bar; Described cross extension bar two ends are respectively arranged with flat side, has angle between the described flat side in two ends, described flat side's end is respectively arranged with projection, and an end of described input shaft, output shaft is left a groove that can cooperate with described flat side respectively, and the bottom of described groove is respectively arranged with the hole.
It is further characterized in that: described flat side is vertical mutually at two ends; Described flat side is a center line with cross extension bar axle center respectively; The hole of described bottom land is a circular port; Described projection is the roundlet column cap.
In the said structure of the present utility model, be used for the cross extension bar diameter can with motor shaft and the same thickness of gear shaft, be implemented in the aperture and use, can send into from the aperture two ends during assembling, can realize correct assembling, avoid conventional shaft joint that the problem in enough assembly manipulation spaces must be arranged; Two socket caps at cross extension bar shaft joint body two ends, stretch into during installation in the boring of input shaft and output shaft spindle nose, play the role of positioning, simultaneously can realize flexibly connecting, can absorb the centerline deviation that input shaft and output shaft occur in making, installing, the shaft joint body can not thrown out because of centrifugal force in 4000～5000rpm high speed rotating, guarantees the smoothness of operation in the transmission process, and enough intensity and durable life-span are arranged.

Fig. 1 is the structural representation of conventional coupling;
Fig. 2 is the structural representation that passes the coupling of aperture;
Fig. 3 is a structural representation of the present utility model.
(5) embodiment
See Fig. 3, the utility model is made up of input shaft 2, output shaft 3 and cross extension bar 8; Cross extension bar 8 two ends are respectively arranged with flat side 11, has angle between the flat side 11 in two ends, optimum angle is 90 °, be that flat side is vertical mutually with flat side, flat side's 11 end is respectively arranged with projection 12, an end of input shaft 2, output shaft 3 is left a groove 9 that can cooperate with flat side 11 respectively, and the bottom of groove 9 is respectively arranged with hole 10.Flat side 11 is a center line with cross extension bar 8 axle center respectively, hole 10 is a circular port, flat side 11 with cross extension bar 8 two ends during installation inserts in the rectangular groove 9 of input shaft, output shaft end, get final product in the hole 10 of the rectangular groove of roundlet column cap 12 insertions 9 bottoms of flat side 11 ends, projection 12 can be other structure, as long as can cooperate with the hole 10 of groove 9 bottoms.
The utility model is used for electric motor car driver, and input shaft is a motor shaft, and output shaft is a gear shaft, and the actual proving effect that uses is good, not only is convenient to install, and transmission performance is good, and driving torque is big, long service life, and smoothness of operation is good.
