Swing disc structure

Abstract

The invention relates to the technical field of hydraulic pumps, and discloses a wobble plate structure which comprises a shell, and the top of the shell is detachably connected with an upper end cover. The two ends of the swing disc body penetrate through the shell, the upper end of the swing disc body extends upwards to penetrate out of the top end face of the upper end cover, the lower end of the swing disc body extends downwards to the lower end cover, the swing disc body can rotate relative to the shell along the axis of the swing disc body, and a sealing piece is arranged between the upper end cover and the shell. Meanwhile, the displacement of the closed type pump is changed by driving the swing disc to rotate to different angles, positive and negative swing angle switching of the swing disc is achieved through rotation of all the angles, large friction force generated by sliding friction in traditional equipment is reduced through rolling friction of the bearing body, the speed of swing disc rotation conversion is increased, and the service life of the closed type pump is prolonged. The flexibility and smoothness of the swinging and circling conversion amount are improved, the noise generated by friction is reduced through rolling friction of the bearing body, and meanwhile, the transmission efficiency is improved.
