Abstract
The utility model discloses an oil pressure damping buffer, which comprises a machine body. The oil pressure damping buffer is characterized in that a sleeve is arranged in the machine body; a tower-type spring is arranged in the sleeve; a ball blocking shell is arranged below the spring; a steel ball is arranged at the lower end of the ball blocking shell; the lower end of the steel ball is connected with a piston in a buckling manner; the lower end of the piston is provided with a mandril; the middle part of the mandril is provided with a spring baffle plate; the mandril is connected with the spring baffle plate by means of interference fit; a framework sealing ring is arranged at one end of the spring baffle plate; a vertical compression spring is arranged between the other end of the spring baffle plate and the piston; a profiled gasket is arranged on a contact part of the vertical compression spring and the piston; and a plug pin is inserted and arranged in the machine body. According to the oil pressure damping buffer, an oil pressure damping buffer force is generated by the action of a compulsive force on the mandril so as to regulate an eccentricity angle of a tension pulley, so that the tension forces of a belt under different tension extents are regulated, and an engine gear system is stably operated.
Description
Technical field
The utility model relates to a kind of oil pressure damping buffer, belongs to mechanical field.
Background technique
The oil pressure damping buffer; The distend wheel that is used for car assisted train carries out belt swelling one device; Mainly form, can adjust the swelling angle of distend wheel automatically according to the holdback force of belt operation by body, sleeve, piston, card spherical shell, push rod, vertical compression spring etc.; Make belt under each working state, can stability and safety move reliably.
The chief component of conventional damping buffer comprises that 26 parts such as body, wax plug, sleeve, vertical compression spring, push rod constitute; Conventional damping buffer wheel reflection power adopts the wax plug to accomplish, and its processing technology complicacy and cost of production are high.On the other hand, conventional damping buffer has certain narrow limitation to working environment, and under the different temperatures environment, output reflection power is inconsistent, thereby influences belt swelling function.
Summary of the invention
The purpose of the utility model provides a kind of oil pressure damping buffer, to overcome the deficiency of existing technology.
To achieve these goals, the utility model adopts following technological scheme:
A kind of oil pressure damping buffer comprises body, it is characterized in that; Be provided with sleeve in the body, be provided with a tower spring in the sleeve, the spring below is provided with the card spherical shell; Card spherical shell lower end is provided with a steel ball, and the steel ball lower end is snapped with piston, and the piston lower end is provided with push rod; The push rod intermediate portion is provided with a spring stop, and push rod adopts interference fit to link to each other with spring stop; Spring stop one end is provided with a backbone sealing ring, is provided with pressing spring always between the spring stop the other end and the piston, and vertical compression spring and piston contacting part are provided with a profiled spacer; Latch is interspersed to be arranged in the body.
Preferably, in said pressure drag Buddhist nun buffer body 1 cavity, be provided with hydraulic oil, its purpose its objective is through spring to be compressed that piston moves downwards, and the space of piston bottom diminishes, and fluid is extruded the back and flows to top; Otherwise fluid flows to the bottom; Produce relative oil pressure pressure and satisfy the required tension force of belt; It is complicated because of whole mechanism to have stopped conventional this product, and cost of production is high; Replace the wax plug response force of finishing the work with oil pressure, thereby guarantee that engine wheel system is worked normally under varying environment.
The utility model oil pressure damping buffer comprises body, is convenient to install, dismantles and maintenance, has also reduced processing request simultaneously; On the other hand, replace the wax plug response force of finishing the work with oil pressure, it is high because of whole mechanism complicated production cost to have stopped conventional this product; Thereby guarantee that engine wheel system is worked normally under varying environment.
