Abstract
The utility model relates to a transmission shaft flange yoke. Two yoke feet are symmetrically arranged on one side surface of a bottom flange plate of the transmission shaft flange yoke, and lug holes are opened on the two yoke feet respectively; the longitudinal section of each of the yoke feet is cone-shaped, installation holes are arranged at positions on the bottom flange plate respectively, and the positions are arranged on two sides of each of the yoke feet; two reinforcing plates are evenly distributed at positions on the bottom flange plate, the positions are located between the two yoke feet, the reinforcing plates are perpendicular to the yoke feet, and the position on the bottom flange plate, which is located between the two reinforcing plates, is inwards recessed to form an inverted-U-shaped hollow cavity; and centripetal inclined tooth surfaces are arranged at positions on the other side surface of the bottom flange plate respectively, and the positions correspond to the installation holes. The connection reinforcing plates are arranged between the two yoke feet, so that overall strength and rigidity of the flange yoke are improved, and stress performances are better; the centripetal inclined tooth surfaces which are pairwise symmetrical are arranged on the end surface of the bottom flange, so that connection bolts only exert functions of connection and are free from bearing shear forces; and besides, by means of a inverted-U-shaped hollow cavity structure which is formed between the two yoke feet, weight of parts is effectively reduced, and raw materials are saved.
Description
Technical field
The utility model belongs to the Universal drive technical field, is specifically related to a kind of transmission shaft flange yoke of driving mechanism.
Background technique
The driving mechanism that transmission shaft and flange yoke form is used more extensive at mechanical field.Usually the factor that affects the transmission shaft dynamic balance accuracy has the following aspects: 1, the straightness accuracy of cardan-shaft tube; 2, the radial clearance of cross assembly is excessive; 3, the matching gap of spline pair; 4, the positioning spigot of flange yoke is too tight or too loose, makes the when mounted difficult coincidence of axis of two flange yokes.Hence one can see that, the quality of flange yoke structural behaviour has considerable influence to the performance of whole transmission shaft and flange yoke combination, with regard to disclosed, it mainly comprises the attachment portions of two fork pin, bottom end tooth flange plate and two fork pin to existing flange yoke such as Chinese patent ZL200420075126.7 " a kind of driving axle end tooth nosing fork ".The shortcoming of this structure is: 1, the attachment portion of two fork pin is stressed less in the course of the work, has larger waste of material; Although 2, fork pin and end tooth flange plate joint, bottom are provided with stiffening rib, but are often destroyed.
Summary of the invention
The purpose of this utility model be to overcome the defective of above-mentioned flange yoke and provide a kind of intensity, rigidity all higher, stress performance good, lightweight transmission shaft flange yoke.
A kind of transmission shaft flange yoke comprises the flange in the bottom dish, one side perimeters of described flange in the bottom dish is arranged with two fork pin, pitch the earhole that is respectively equipped with on the pin for the perforation of transmitting the universal-joint cross trunnion active force for two, and two earholes of pitching on the pin are coaxial, improvement is: the longitudinal cross-section of each fork pin is tapered, is respectively equipped with mounting hole on the flange in the bottom dish of each fork pin both sides; Be laid with two stiffening plates on the flange in the bottom dishes of described two forks between the pin, and stiffening plate is perpendicular to the fork pin, the flange in the bottom dish between two stiffening plates concaves and forms an inverted U-shaped cavity.
Be respectively the flank of tooth with the mounting hole corresponding part on the another side of described flange in the bottom dish, the flank of tooth is the spline-simulating flank of tooth, and described tooth bar is the radiation wire along radial direction and distributes.
Utilize the utility model transmission shaft flange yoke to realize: 1, fork pin cross section is tapered, is provided with stiffening plate between the fork pin, thus Effective Raise bulk strength, rigidity, stress performance is better.2, two fork pin and flange in the bottom dish form an inverted U-shaped cavity structure, have effectively alleviated pts wt, have saved raw material.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Embodiment
A kind of transmission shaft flange yoke comprises flange in the bottom dish 7, one side perimeters symmetry of described flange in the bottom dish 7 has two fork pin 4, pitch the earhole 5 that offers respectively on the pin 4 for the perforation of transmitting the universal-joint cross trunnion active force for two, and two earholes 5 of pitching on the pin are coaxial.The longitudinal cross-section of each fork pin 4 is tapered, offers respectively mounting hole 1 on the flange in the bottom dish 7 of each fork pin both sides.Be respectively the flank of tooth 6 with earhole 5 corresponding parts on the another side of flange in the bottom dish 7, the flank of tooth 6 is the spline-simulating flank of tooth, and tooth bar is the radiation wire along radial direction and distributes.Be laid with two stiffening plates 3 on the flange in the bottom dish 7 of two forks between the pin 4, and stiffening plate 3 concaves perpendicular to the flange in the bottom dish 7 between 4, two stiffening plates 3 of fork pin and forms an inverted U-shaped cavity 2.
The utility model fork pin cross section is tapered, and between two fork pin, be provided with the connection reinforcement plate, thereby bulk strength, rigidity have been improved, stress performance is better, and the flange in the bottom end face is provided with symmetrical in twos centripetal pitch face, can make like this connecting bolt only play connection function, and be not subjected to shearing force, between two fork pin, form inverted U-shaped cavity structure in addition, thereby effectively alleviated pts wt, saved raw material.
Claims (2)
1. transmission shaft flange yoke, comprise the flange in the bottom dish, one side of described flange in the bottom dish is arranged with two fork pin, pitch the earhole that is respectively equipped with on the pin for the perforation of transmitting the universal-joint cross trunnion active force for two, and two earholes of pitching on the pin are coaxial, it is characterized in that: the longitudinal cross-section of each fork pin is tapered, is respectively equipped with mounting hole on the flange in the bottom dish of each fork pin both sides; Be laid with two stiffening plates on the flange in the bottom dishes of described two forks between the pin, and stiffening plate is perpendicular to the fork pin, the flange in the bottom dish between two stiffening plates concaves and forms an inverted U-shaped cavity.
