Detailed Description

In order that those skilled in the art will be able to fully practice the present invention, it will be further described with reference to the accompanying drawings and specific examples.

As shown in figure 1, the transmission shaft comprises a connecting handle 1, wherein two ends of the connecting handle 1 are coaxially connected with a ball head 2, the ball heads 2 at two ends of the connecting handle 1 are connected with pins 3 in parallel, and the axes of the pins 3 penetrate through the center of the ball head 2 and are perpendicular to the axis of the connecting handle 1. The structure of bulb 2 at both ends makes the transmission shaft possess universal connection function, and parallel pin 3 makes the transmission shaft can take place to deflect for the axle pin 3.

The end of the ball 2 opposite the stem 1 has a circular flat end 21. The round plane end 21 is beneficial to the fact that a certain gap is formed between the ball head 2 and the ball cage for facilitating lubrication when the ball head and the ball cage are matched and connected.

The transmission shaft is preferably structured such that the diameter of the connecting shank 1 is smaller than that of the ball head 2.

As shown in fig. 2, in a transmission device, one end of a shaft seat 4 is a ball cage 41 capable of accommodating a ball head 2, the other end of the shaft seat is a shaft sleeve 42 coaxially connected with the ball cage 41, the ball cage 41 is provided with a groove 44 capable of accommodating a pin 3, an arc notch 43 is arranged on the outer edge of the ball cage 41 in the vertical direction of the axis of the groove 44, and the inner diameter of the arc notch 43 is larger than the diameter of the ball head 2. The pin 3 and the groove 44 are matched to realize transmission connection, and the arc notch 43 is used for accommodating part of the ball head 2 or the connecting handle 1 when the transmission shaft deflects by taking the pin 3 as an axis.

In a more preferable embodiment, after the pin 3 is received in the bottom end of the groove 44, the ball head 2 is completely received in the ball cage 41, and the inner diameter of the circular arc gap 43 is larger than the diameter of the connecting handle 1. Therefore, the connection between the ball head 2 and the ball cage 41 is firmer, and the circular arc notch 43 only needs to accommodate the deflected connecting handle 1.

The transmission device is used for the burnishing machine tool and comprises a power system and a roller squeezing seat 5, and the transmission device is connected with an output shaft of the power system and an input shaft of the roller squeezing seat 5 through a shaft sleeve 42.
