Abstract
The utility model relates to an end cap device for an output shaft end of a large motor. The end cap device for the output shaft end of the large motor includes an n-shaped iron end cap and a spherical bearing disposed in and concentric with the iron end cap. An output shaft of the large motor passes through centers of the iron end cap and the spherical bearing. The bottom of the inner of the iron end cap is provided with an arc surface cooperating with one end of the spherical bearing. The other end of the spherical bearing is in sleeve connection with a fixing annular bearing pressing plate. At least three arc warping edges cooperating with the other end of the spherical bearing are uniformly disposed along a circumferential direction of the inner diameter of the bearing pressing plate. An end face of the iron end cap is fixed with an annular connecting plate coaxial with the iron end cap. The central portion of the connecting plate protrudes toward the inner of the iron end cap, abuts against the bearing pressing plate and is provided with a through hole. The arc warping edges of the bearing pressing plate protrude from the through hole of the connecting plate. According to the utility model, the parts and processes are reduced; the spherical bearing is effectively fixed; deformation and failure of a bearing chamber which are caused by long-time friction of the large motor under high torque are also overcome; and therefore the motor is more reliable in performance and longer in service life.
