Self-aligning spherical universal joint

Abstract

The invention discloses a self-straightening spherical universal joint. The self-straightening spherical universal joint comprises four parts: (1) a ball joint, (2) an axial length self-adjusting slide sleeve, (3) a self-straightening spring, and (4) an end fixing piece. When the self-straightening spherical universal joint is used, a rotating joint is connected in; one end of a steam outlet pipe is fixedly connected with one end of the universal joint; a universal joint axial groove-carried slide sleeve (length adjusting guide sleeve) is arranged at the other end of the universal joint, and is connected with a fixed frame arranged in a cylinder outlet; and a universal joint center connecting piece is provided with the self-straightening spring. During working, power from rotation of a cylinder is transferred to the universal joint axial groove-carried slide sleeve through the cylinder and the universal joint connecting piece, is transferred to a universal joint shaft, and is transferred to the other end of the universal joint to a rotating joint connecting piece to a rotating joint through joint pin shafts arranged on four spherical joints and forming multiple angles in space. The self-straightening spherical universal joint eliminates radial force generated by rotation of the cylinder to an inner pipe of the rotating joint, and reduces the damage times of the rotating joint.

Description

technical field [0001] The invention relates to a drum type silk drying machine, in particular to a self-aligning spherical universal joint. Background technique [0002] In the production process of tobacco shreds, drum-type wire drying machines are commonly used. There is a main part on the wire drying machine, the heat sink for steam entering the cylinder and the output of condensed water - the rotary joint. Its outside is stationary, and the inner pipe follows When the drum rotates, due to the coaxiality error between the center of the cylinder and the center of the rotary joint, the inner tube of the rotary joint and the outer shell form a radial relative movement, which aggravates the damage of the internal seal of the rotary joint. At present, the silk dryer connects the cylinder body and the rotary joint to connect the steam pipe and the condensate pipe in the form of a hose.

[0002] In the production process of tobacco shreds, drum-type wire drying machines are commonly used. There is a main part on the wire drying machine, the heat sink for steam entering the cylinder and the output of condensed water - the rotary joint. Its outside is stationary, and the inner pipe follows When the drum rotates, due to the coaxiality error between the center of the cylinder and the center of the rotary joint, the inner tube of the rotary joint and the outer shell form a radial relative movement, which intensifies the damage of the internal seal of the rotary joint.

At present, the silk dryer connects the cylinder body and the rotary joint to connect the steam pipe and the condensate pipe in the form of a hose. The power of the rotation of the inner tube of the rotary joint uses a horizontal bar to radially make the outlet edge of the cylinder body and the end of the rotary joint The central connection, although it can make the rotary joint rotate with the rotation of the drum, it transmits power to the rotation of the rotary joint in the form of "prying". The inner tube of the joint forms a radial force, which causes certain damage to the rotary joint, which increases the frequency of damage to the rotary joint, affects the normal operation of the equipment, negatively affects the product quality, and increases the maintenance cost

The fixed form of the original design of the rotary joint restricts the fixed part of the rotary joint too much, and the rotary joint generates vibration during operation. With the rotation of the drum, the inner tube of the rotary head swings radially, which aggravates the wear of the inner sleeve of the central tube, resulting in steam intake and Backwater collusion will have a great impact on normal operation
