Detailed Description
The present invention will be further described with reference to the following examples.
As shown in figures 1-6, an embodiment of the present invention, a swing hydraulic cylinder with an oil outlet, is provided with a cylinder assembly 4, a left support plate 1 and an end cover 7 are respectively fixed on the left and right sides of the cylinder assembly 4, the left support plate 1 and the end cover 7 are connected with the inner cavity of the cylinder assembly 4 in a sealing manner, a locking nut 9 is fixedly arranged in the inner hole on the right side of the end cover 7 in a sealing manner, a right support plate 8 is fixedly arranged on the right side of the end cover 7, two side plates 2 are fixedly arranged on the lower side of the outer portion of the cylinder assembly 4 perpendicularly to the left support plate 1, the large planes of the two side plates 2 are parallel to each other and are parallel to the axis of the cylinder assembly 4, an inner gear ring 5 is fixedly arranged on the inner wall of the cylinder assembly 4, inner gear ring inner helical teeth are arranged on the inner wall of the inner gear, the middle sleeve oblique outer teeth 601 are in meshing connection with inner gear ring oblique inner teeth arranged on the inner wall of the inner gear ring 5, an inner shaft 3 is arranged inside the middle sleeve 6, middle sleeve oblique inner teeth 602 are arranged on the inner wall of the middle sleeve 6, inner shaft oblique outer teeth 305 are arranged on the outer circumference of the inner shaft 3, the inner shaft oblique outer teeth 305 are in meshing connection with the middle sleeve oblique inner teeth 602, a left oil cavity 13 and a right oil cavity 14 are respectively arranged on two sides of the middle sleeve 6, a left oil hole 401 and a right oil hole 402 are arranged on the outer circle of the cylinder component 4, and the left oil hole 401 and the right.
When the left oil cavity 13 enters hydraulic oil, the pressure of the hydraulic oil pushes the middle sleeve 6 to form translation, meanwhile, as the middle sleeve 6 is meshed with the inner gear ring 55 through helical teeth, the middle sleeve 6 forms rotation while translating, the rotation action drives the inner shaft 3 to rotate, and therefore rotation output is formed, and the structure outputs rotation force through the pressure of the hydraulic oil.
Because the inner gear ring 5 is arranged in the barrel component 4, the inner gear ring 5 is meshed with the middle sleeve 6, the middle sleeve 6 forms translation and rotation when receiving a rotating force, the middle sleeve 5 can drive the inner shaft 3 to rotate, and the inner shaft 3 forms large-angle rotation under the condition of short stroke.
