Specific embodiment
Now in conjunction with Detailed description of the invention a specific embodiment of the invention.
Low abrasion whirl compensator comprising outer cylinder 1, inner cylinder 2, outer cylinder are variable-diameter structure, and left section of inner cylinder is located at outer cylinder
Enlarged diameter section in, characterized in that the outer wall of inner cylinder covers rubber sleeve 4, is cased with pressure-bearing cylinder 6, pressure-bearing cylinder on the outer wall of rubber sleeve
Left and right ends it is radially inwardly extending respectively have a left anchor ring, right anchor ring, the inner circle and rubber sleeve of left anchor ring and right anchor ring it is outer
Wall contact, the left and right ends of rubber sleeve extend radially outward out left flange, right flange, the left anchor ring and right ring of pressure-bearing cylinder respectively
Face is located between the left flange of rubber sleeve, right flange；It is equipped with baffle ring 3 in the left side of rubber sleeve, baffle ring is fixedly connected on outer cylinder
On inner wall, the inner circle of baffle ring is matched with the outer circle of inner cylinder, is equipped with gland 5 on the right side of rubber sleeve, and gland is equipped with pressure head 13,
Pressure head 13 puts in outer cylinder, and position of the inner cylinder between baffle ring and pressure head is a lug boss 7, and the effect of lug boss is to prevent inner cylinder
Along axial float；The outer wall of pressure head is matched with the inner wall of outer cylinder, and the inner circle of pressure head is matched with the outer circle of lug boss, gland
Flange 12 is connect with the flange 11 of outer cylinder by bolt 14, and the inner circle of the flange of gland is matched with the outer circle of inner cylinder, pressure-bearing cylinder
Left anchor ring on be symmetrically tightly connected multiple drainage tubes 8, drainage tube sequentially passes through the left flange and baffle ring of rubber sleeve.
The rubber sleeve is made of silicon rubber or ethylene propylene diene rubber.
The sealing principle of low abrasion whirl compensator is: under the pretightning force effect of gland, the left flange and gear of rubber sleeve
Ring right side is in sealing contact and rubber sleeve and pressure-bearing cylinder constitute a seal cavity, and the left flange of rubber sleeve and baffle ring right side are close
The radial leakage point for closing fluid in outer tube is touched in sealing-in, and seal cavity is introduced fluid in outer tube by drainage tube, flowed in outer tube
There is body pressure rubber sleeve to be made to be close to inner cylinder, and rubber sleeve is close to the axial leakage point that inner cylinder closes fluid in outer tube；Baffle ring
Inner circle is matched with the outer circle of inner cylinder carries out reducing pressure by regulating flow to fluid in outer tube, and fluid is made to be less than rubber along the pressure of axial leakage
