摘要: A fluid pressure cylinder includes a cylinder body, a piston accommodated in the cylinder body to define first and second pressure chambers therein, means for supplying fluid to each chamber to reciprocate the piston between a first stroke end and a second stroke end, first and second bumper surfaces, an annular cushion retainer connected to the first bumper surface, and an elastomeric cushion for deforming and cushioning an impact produced when the piston reaches the first stroke end. The bumper surfaces approach each other when the piston reaches the first stroke end and separate from one another when the piston moves toward the second stroke end. The cushion has a shape corresponding generally to a hollow conical section. The cushion includes a base section retained by the cushion retainer and a buffer section joined to the base section. The buffer section has an outer surface for contacting the second bumper surface and an inner surface that faces the first bumper surface. The outer surface forms a circular seal with the second bumper surface when the piston approaches the first stroke end. The cushion is flexed such that the buffer section moves toward the first bumper surface. The buffer section moves away from the first bumper surface when the piston moves towards the second stroke end.
摘要翻译: 液压缸包括缸体,容纳在缸体中以在其中限定第一和第二压力室的活塞,用于向每个室供应流体以在第一行程末端和第二行程末端之间使活塞往复运动的装置,第一和第二 保险杠表面,连接到第一保险杠表面的环形缓冲保持器,以及用于使活塞到达第一行程末端时产生的冲击变形和缓冲的弹性衬垫。 当活塞到达第一行程端时,保险杠表面相互接近并且当活塞向第二行程端移动时彼此分离。 该衬垫具有通常对应于中空圆锥形部分的形状。 衬垫包括由衬垫保持器保持的基部部分和与基部接合的缓冲部分。 缓冲部分具有用于接触第二保险杠表面的外表面和面对第一保险杠表面的内表面。 当活塞接近第一行程末端时,外表面与第二保险杠表面形成圆形密封。 缓冲部弯曲使得缓冲部分朝向第一保险杠表面移动。 当活塞向第二行程端移动时,缓冲部分从第一保险杠表面移开。

摘要: Disclosed is a braking apparatus for a rod-less cylinder. A transfer member (3) arranged outside a cylinder body (1) is coupled to a piston (2) disposed movably within the cylinder body (1), and moves together with the piston (2). A brake rail (8) is arranged on the outer side surface of the cylinder body (1), extending in parallel to the moving direction of the piston (2). A braking member (16) faces the brake rail (8) in such a manner as to be engageable therewith, and disengageable therefrom, and is moved to a contact position where it engages the brake rail (8), and a release position where it disengages from the brake rail (8) by an operation member (17), to accomplish the braking and unbraking of the transfer member (3).
