Buffer starter

Abstract

The invention discloses a buffer starter comprising a starter body. Pusher dogs are arranged on two sides of the starter body and are fixedly connected with the starter body through a sealing pad, pressing pieces are arranged in the pusher dogs and made of elastic materials, the insides and two ends of the pressing pieces form hollow cavity structures, buffer springs which are spiral springs are arranged in hollow cavities, the height of the buffer springs is smaller than the length of the pressing pieces, two ends of the buffer springs can extend out of the pressing pieces when in elastic pressing, and the pusher dogs are respectively connected with a pusher dog shaft and a crankshaft. The buffer starter effectively solves the problem that existing starters are low in rotation speed, high in operation load and a stay cord is tight to add difficulty in starting during starting, various parts are not collided and worn, and effective buffer and energy storage are realized under the action of the buffer springs, therefore, recoil force of the air cylinder of a gasoline engine is effectively buffered, vibration is reduced to the great extent and starting is more labor saving.

Description

technical field [0001] The invention relates to a starting device, in particular to a buffer starter. Background technique [0002] At present, the starting methods of gasoline engines or diesel engines are hand recoil start. The operator must overcome the gas pressure in the cylinder to rotate the crankshaft when starting by hand, so as to achieve the required ignition speed. When starting, the rope starter used pulls the rope wheel, and the rope wheel directly drives the flywheel and the crankshaft to rotate to start the fuel engine. , but the inertia of the flywheel assembly is large, and it is difficult to start. It is necessary to pull the rope pulley vigorously, and the impact force on the entire starting device is large when starting, and the pull rope has obvious recoil phenomenon, which may cause short service time and maintenance. The number of times is many, and the replacement is frequent, so the material requirements for the starting device are also relatively ...

Problems solved by technology

The operator must overcome the gas pressure in the cylinder to rotate the crankshaft when starting by hand, so as to achieve the required ignition speed. When starting, the rope starter used pulls the rope wheel, and the rope wheel directly drives the flywheel and the crankshaft to rotate to start the fuel engine. , but the inertia of the flywheel assembly is large, and it is difficult to start. It is necessary to pull the rope pulley vigorously, and the impact force on the entire starting device is large when starting, and the pull rope has obvious recoil phenomenon, which may cause short service time and maintenance. The number of times is high and the replacement is frequent, so the material requirements for the starting device are relatively high, which is not conducive to economical saving
