Description
Technical field
The utility model relates to a kind of cardan wheel, is specifically the removable cardan wheel of the detachable maintenance of a kind of single parts.
Background technology
Cardan wheel refers to the support that is arranged on castor wheel, in dynamic load or static load situation, can carry out the rotation of horizontal 360-degree.At present, because each parts of cardan wheel are generally fixed connection with rivet or welding, therefore cardan wheel entirety is generally non-dismountable, cardan wheel cannot carry out the repair and replacement of single parts the situation of certain damage of components is next like this, can only wholely change, make like this maintenance cost improve.And if adopt existing plain bolt that cardan wheel is assembled, can compress the ball up and down of cardan wheel, and make cardan wheel cannot normal level 360 degree rotations.
Utility model content
The technical problems to be solved in the utility model is, provides a kind of and make the repair and replacement of single parts energy, the cost of cardan wheel low, can make the removable cardan wheel of the normal work of cardan wheel.
The technical solution of the utility model is, a kind of removable cardan wheel with following structure is provided, it comprises upper bracket, lower bracket, roller, axle bumper bolt, axle bumper nut, hold-down nut and some upper balls and some lower balls, described upper bracket is the cylindrical body structure that lower end closure and cross-sectional plane are U-shaped, described lower bracket is the cylindrical body structure that upper end closure and cross-sectional plane are U-shaped, described roller and rotatable also removable connection of lower bracket, described axle bumper bolt comprises head one-body molded and that coaxially arrange successively from the bottom to top, pad portion, shoulder, polished rod and screw rod, the diameter of described pad portion is greater than the diameter of head and shoulder, described axle bumper nut comprises lower protruding wall one-body molded and that coaxially arrange successively from the bottom to top, axle bumper dish and epirelief wall, the diameter of described axle bumper dish is greater than the diameter of lower protruding wall and epirelief wall, described screw rod is successively through lower bracket, upper bracket and axle bumper nut screw, described hold-down nut screws on screw rod and with the upper end of axle bumper nut to be close to, described upper ball is all movable between axle bumper dish and the inwall of upper bracket bottom, described lower ball is all movable between pad portion and the inwall at lower bracket top.
Described roller and lower bracket are rotatable and refer to removable connection, and on the madial wall of described lower bracket, by screw, bearing pin is installed, described roller is rotatably arranged on bearing pin.
Adopt after above structure, the utility model compared with prior art, has the following advantages: due to the pad portion of axle bumper bolt can axial limiting under ball, the axle bumper dish of axle bumper nut can axial limiting on ball, can ensure that like this ball normally rolls; Owing to adopting axle bumper bolt to fix, be removable connection again, make the repair and replacement of single part energy, the cost of cardan wheel low, can make cardan wheel normally work, can normal level 360 degree rotations.
