Abstract
An assembling structure of a piston and piston rings comprises a piston (1) and two piston rings (2), wherein two adjacent ring grooves (3) are arranged on the piston (1), each of the two ring grooves is equipped with an opening (6), the piston rings (2) are respectively positioned inside the ring grooves (3), the two openings of the piston rings are staggered at 180 degrees, limit grooves (4) are respectively arranged on the ring grooves (3), limit bosses (5) respectively engaged with the limit grooves (4) are disposed on the piston rings (2), and the limit bosses (5) are in semi-limit state inside the limit grooves (4) to lead the piston rings to rotate at certain angles. By utilizing the above technical scheme, the assembling structure of a piston and piston rings avoids aligning of the openings of the two piston rings, remarkably reduces piston blow-by quantity, increases power and torque of an engine, and prolongs the service life of engine oil.
Description
Technical field
The utility model relates to the component on a kind of motor, the assembly relation of particularly a kind of piston and piston ring.
Background technique
The gas with pressure that traditional vehicle motor takes place the firing chamber adopts twice compression ring up and down substantially, and opening direction interlaces 180 ° and seals, because conventional piston, the reason of the structural type of piston ring self design principle, piston ring can rotate freely in annular groove at random, so motor is after the running regular period, the opening of two rings might align, can cause the increase of piston air leakage, like this, make the interior exhaust gas pressure of crankcase too high on the one hand, can influence the motion of piston, gas pressure in the firing chamber also can reduce, thereby reduced the power and the moment of torsion of motor, the high pressure-temperature gas after a large amount of on the other hand burnings seals in the crankcase from the opening of piston ring alignment, not only can destroy the lubricated environment between cylinder barrel and the piston, and allowed lubricated, chemical reaction at high temperature takes place in the petrol engine of refrigerating function, the variation of matter taking place, quicken the inefficacy of machine oil, has shortened the working life of machine oil.
Summary of the invention
The purpose of this utility model just provides the assembly structure of a kind of piston and piston ring, and it can avoid the register of two-piston ring, reduces piston air leakage, to improve the power and the moment of torsion of motor, can also prolong the working life of machine oil.
The purpose of this utility model is to realize like this, comprise piston and two piston rings, wherein, piston is provided with two adjacent annular grooves, all offers opening on two piston rings, piston ring lays respectively in the annular groove, and the opening of two-piston ring interlaces 180 °, is respectively arranged with restraining groove on annular groove, is provided with the positive stop lug boss that matches with restraining groove on piston ring, positive stop lug boss is in half spacing state in restraining groove, piston ring can be turned an angle.
When the piston ring in the model utility being installed in the annular groove of piston, and the positive stop lug boss on the piston ring is positioned at restraining groove, in use, because positive stop lug boss on the piston ring and the restraining groove on the annular groove form partly limit-type, half limit-type be positive stop lug boss on the piston is made several angle in restraining groove rotation, cell wall by restraining groove carries out spacing to positive stop lug boss, piston ring can be rotated freely in annular groove, interlace all the time 170 °～190 ° angle of the opening that has guaranteed the two-piston ring again, avoided the register of two-piston ring, obviously reduce piston air leakage, improved the power and the moment of torsion of motor, also prolonged the working life of machine oil.
Owing to adopted technique scheme, the utility model to avoid the register of two-piston ring, obviously reduced piston air leakage, improved the power and the moment of torsion of motor, prolonged the working life of machine oil.

Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, 2, 3, the utility model comprises piston 1 and two piston rings 2, wherein, piston 1 is provided with on two adjacent 3, two piston rings 2 of annular groove and all offers opening 6, and piston ring 2 lays respectively in the annular groove 3, and the opening of two-piston ring interlaces 180 °, be respectively arranged with restraining groove 4 on annular groove 3, be provided with the positive stop lug boss 5 that matches with restraining groove 4 on piston ring 2, restraining groove 4 constitutes half limit-type structure with positive stop lug boss 5.
As Fig. 4,5, shown in 6, when the piston ring in the model utility being installed in the annular groove 3 of piston 1, and the positive stop lug boss on the piston ring 25 is positioned at restraining groove 4, in use, because the positive stop lug boss 5 on the piston ring 2 is limit-type with restraining groove 4 formation half on the annular groove 3, should half limit-type then be positive stop lug boss on the piston is made several angle in restraining groove rotation, cell wall by restraining groove carries out spacing to positive stop lug boss, piston ring can be rotated freely in annular groove, interlace all the time 170 °～190 ° angle of the opening that has guaranteed the two-piston ring again, avoided the register of two-piston ring, obviously reduced piston air leakage, improve the power and the moment of torsion of motor, also prolonged the working life of machine oil.
As shown in Figure 4, it is cylindric that positive stop lug boss 5 can be, and restraining groove 4 is a cylindrical groove.
As shown in Figure 5, positive stop lug boss 5 can be taper, and restraining groove 4 is a cone tank.
As shown in Figure 6, the cross section of positive stop lug boss 5 is rectangular, and the rectangular positive stop lug boss of restraining groove 4 and cross section matches.
In sum, in order to realize half limit method to piston ring, the utility model also can adopt the positive stop lug boss and the restraining groove of other structure shape, certainly, spacing slotted eye can also be set on piston ring, and the positive stop lug boss that matches with spacing slotted eye is set on the annular groove.
