Detailed Description
The technical solution of the present invention is further explained by the specific embodiment with reference to fig. 1 to fig. 2.
A machined, convenient friction reducing piston as shown in fig. 1, comprising: piston base member 1, arc tile 12 and jump ring 8, piston base member 1 adopts cast aluminium material, and inside is provided with cavity 14, reduces the dead weight. An oil ring groove 3 is formed in the outer circle of the piston base body 1, a combined oil ring can be installed, and redundant lubricating oil in the cylinder body is scraped when the piston moves. Be provided with the gas ring groove 2 that is located oil ring groove 3 top on the 1 excircle of piston base member, 2 gas ring grooves 2 quantity are 2, carry out the installation of gas ring respectively.
The embedded groove 13 that corresponds with arc tile 12 is provided with to 14 inner wall symmetries of cavity, the indent is provided with oil storage tank 11 in the embedded groove 13, can directly carry out the machine-shaping of embedded groove 13 and oil storage tank 11 in cavity 14 through machining center, need not pre-buried salt core, and processing is convenient.
The setting of arc tile 12 carries out the shutoff of oil storage tank 11 in embedded groove 13, makes things convenient for the oil storage of oil storage tank 11, the width of arc tile 12 is corresponding with the width of embedded groove 13, and the cooperation is inseparable, promotes structural stability. Be provided with the first arc wall 6 that corresponds with jump ring 8 respectively on the arc tile 12 concave surface, be provided with the second arc wall 7 that meets with first arc wall 6 in the 14 inner walls of cavity, jump ring 8 sets up in first arc wall 6 and second arc wall 7, carries out arc tile 12 spacing, and the dismouting is convenient.
The lower portion of the piston base body 1 is symmetrically provided with pin holes 9 located below the oil storage tank 11, so that the pin shaft can be conveniently installed, a clamp spring installation ring groove 10 is formed in each pin hole 9, a pin shaft limiting clamp spring can be installed, and the end portion of the pin shaft is limited.
