The invention discloses a novel bearing with a base. The novel bearing with the base comprises a bearing mounting base, as well as a front side fixed end cover and a back side fixed end cover which are mounted on the bearing mounting base spirally, wherein a front end bearing, a bearing inner ring spacer bush and a back end bearing are embedded in a bearing mounting hole of the bearing mounting base; the periphery of the bearing inner ring spacer bush is sleeved with a bearing outer ring spacer bush; a front side inner ring pressing ring is embedded in a front side end cover through hole of the front side fixed end cover; a front side spring is mounted between the front side inner ring pressing ring and the front side fixed end cover; a back side inner ring pressing ring is embedded in a back side end cover through hole of the back side fixed end cover; a back side spring is mounted between the back side inner ring pressing ring and the back side fixed end cover; the bearing outer ring spacer bush comprises a front side outer ring spacer bush and a back side outer ring spacer bush; a pre-tightening oil pressing cavity is formed between a back side spacer bush extending part at the end part of the back side outer ring spacer bush and the inner wall of the bearing mounting hole; the bearing mounting base is provided with an oil passing hole. The novel bearing with the base can adjust the bearing pre-tightening force according to different rotating speeds so as to meet the requirements of adapting to different rotating speeds, and is novel in structural design.

The present invention provides an interventional robot system and a readable storage medium. A touch switch of the interventional robot system is arranged on an operating rod and is connected to a processor for sending the current state of the switch to the processor; the main-end encoder is arranged in the operation on the rod, and connected with the processor, for sending the operating rod displacement formed by the operating rod being controlled to perform the current operation; the zero position sensor is arranged on the base and connected with the processor, and is used for sending the sensor to the processor Current state; the processor is used to receive the joystick displacement sent by the master encoder, the sensor current state sent by the zero position sensor, and the switch current state sent by the touch switch; and control the interventional robot based on the joystick displacement, sensor current state, and switch current state The movement corresponding to the displacement of the operating rod is performed from the end, thereby ensuring precise control of the movement of the slender medical device and eliminating ineffective operations.

The present invention relates to a transmission, in particular to an eleven-speed transmission based on a planetary gear train, which solves the limitations of existing four-speed and six-speed transmissions in terms of fuel economy, responsiveness, and stability. question. The eleven-speed transmission based on the planetary gear system of the present invention includes a transmission housing and a planetary gear system. The planetary gear system includes four planetary rows and seven shifting assemblies arranged on the same shaft system. The four planetary row assemblies pass through The rotating shaft and other connecting components form eight rotating bodies. The shifting component uses clutches and brakes to change the degree of freedom of the planetary gear train. The shifting speed of at least eleven forward gears and at least two reverse gears is obtained, with a more optimized speed ratio, which significantly improves the power transmission performance and fuel economy of the vehicle.

The novel bearing with the base comprises a bearing mounting base, as well as a front side fixed end cover and a back side fixed end cover which are mounted on the bearing mounting base spirally, wherein a front end bearing, a bearing inner ring spacer bush and a back end bearing are embedded in a bearing mounting hole of the bearing mounting base; the periphery of the bearing inner ring spacer bush is sleeved with a bearing outer ring spacer bush; a front side inner ring pressing ring is embedded in a front side end cover through hole of the front side fixed end cover; a front side spring is mounted between the front side inner ring pressing ring and the front side fixed end cover; a back side inner ring pressing ring is embedded in a back side end cover through hole of the back side fixed end cover; a back side spring is mounted between the back side inner ring pressing ring and the back side fixed end cover; the bearing outer ring spacer bush comprises a front side outer ring spacer bush and a back side outer ring spacer bush; a pre-tightening oil pressing cavity is formed between a back side spacer bush extending part at the end part of the back side outer ring spacer bush and the inner wall of the bearing mounting hole; the bearing mounting base is provided with an oil passing hole. The novel bearing with the base can adjust the bearing pre-tightening force according to different rotating speeds so as to meet the requirements of adapting to different rotating speeds, and is novel in structural design.

The invention relates to the technical field of textile fabrics, and discloses a variable speed winding device with an adjustable radius of the main transmission wheel, including a mounting frame, which is characterized in that: the interior of the mounting frame is fixedly connected with a wire inlet, and the mounting frame The inside of the mounting frame is fixedly connected with a guide wheel, the inside of the installation frame is fixedly connected with a slide bar, the outside of the slide bar is connected with a buffer spring, and the outside of the slide bar is slidably connected with a pressure line slider. The inside of the wire slider is fixedly connected with a wire pressing spring, and the bottom of the wire pressing spring is fixedly connected with a wire pressing rod. Through the cooperation of the buffer spring and the wire pressing slider, the winding device needs a short time due to a failure in the previous process. When the yarn transmission is stopped and the winding device continues to operate, the yarn compresses the buffer spring, so that the yarn can continue to be wound at one end length, which acts as a buffer to avoid yarn breakage and fully guarantee the integrity of the yarn , to ensure the quality of the yarn, and improve the winding efficiency of the yarn.
