Abstract
The utility model discloses an improved gear driving mechanism, oil storage grooves are uniformly distributed on the inner wall of the piston cylinder sleeve in a moving range of the piston; the rabbet diameter of the oil storage groove is from 0.01mm to 0.02mm, the depth of the groove is from 0.001mm to 0.005mm, and the distance of the adjacent oil storage groove is from 0.2mm to 0.5mm; in the utility model, smooth piston cylinder sleeve inner wall in the prior art is discarded; as the oil storage grooves are uniformly arranged on the inner wall of the piston cylinder sleeve, lubricating oil is stored in the oil storage grooves, dynamic lubricating balance in the piston movement is built on the inner wall of the piston cylinder sleeve in the moving range of the piston, and the service life of the piston and the piston cylinder sleeve is prolonged.
Description
Technical field
The utility model relates to the improvement of piston-cylinder.
Background technique
Piston-cylinder inner wall surface now is smooth, and lubricant oil can't be evenly distributed on the piston-cylinder inwall.When piston during to-and-fro motion, is prone to the dry friction phenomenon of piston and cylinder sleeve in cylinder sleeve, a large amount of heats of generation have increased the load of piston and piston-cylinder, have reduced the working life of piston and piston-cylinder.
The model utility content
At the deficiencies in the prior art part, the utility model provides a kind of improved piston-cylinder.The routing motion of this piston-cylinder and piston is more accurate, and less energy consumption is more durable.
For achieving the above object, technical solutions of the utility model are:
Improved piston-cylinder has been evenly equipped with oil storage grooves on the piston-cylinder inwall in the range of movement of piston.
The notch diameter of described oil storage grooves is that 0.01mm-0.02mm, groove depth are 0.001mm-0.005mm.
Adjacent oil storage grooves spacing is 0.2mm-0.5mm.
The usefulness of technique scheme is:
The utility model is abandoned piston-cylinder inwall smooth in the prior art.It evenly is provided with oil storage grooves on the piston-cylinder inwall, this oil storage grooves can store lubricant oil, sets up the dynamically lubricating balance in the piston motion thus on the piston-cylinder inwall in the piston motion scope.Avoid piston and piston-cylinder because of the wearing and tearing that dry friction causes, prolonged the working life of piston and piston-cylinder.
Description of drawings
Fig. 1 is the utility model piston and piston-cylinder mated condition structure for amplifying schematic representation.
Embodiment
The utility model now is described in conjunction with the accompanying drawings and embodiments.
Improved piston-cylinder as shown in Figure 1 is the wearing and tearing of avoiding piston 1 and piston-cylinder 2 to cause because of dry friction, and piston-cylinder 2 inwalls of the utility model in piston 1 range of movement are evenly distributed with oil storage grooves 21.The notch diameter of this oil storage grooves is that 0.01mm-0.02mm, groove depth are 0.001mm-0.005mm, and adjacent oil storage grooves spacing is 0.2mm-0.5mm.Set up the dynamically lubricating balance in the piston motion thus on the piston-cylinder inwall in the range of movement of piston.
Claims (3)
1. improved piston-cylinder is characterized in that: be evenly equipped with oil storage grooves on the piston-cylinder inwall in the range of movement of piston.
2. improved piston-cylinder as claimed in claim 1 is characterized in that: the notch diameter of described oil storage grooves is that 0.01mm-0.02mm, groove depth are 0.001mm-0.005mm.
