Bendix starter - is the smallest and at the same time an important element of the design of a starter.This element was invented by American Vincent Bendix.The main objective of this mechanism is a temporary connection to the starter shaft wreath of a flywheel to the crankshaft.
What is it?
This mechanism - a device with a gear drive and freewheel.Bendix on the starter is located on the helical shaft.Due to its design, this item allows you to go from the starter gear to connect at startup with the engine flywheel.When the gear rotates, the inertia of the assembly causes the gears to move Bendix spiral.Thus, the active element interacts with the ring gear of the engine.
After the engine is successfully wound, the rotation speed increases in the latter part several times and superior performance of turns drive gear, whereby it is moved back by the screw shaft and out of engagement with the crown.
device Bendix :
- drive gear;
- overrunning clutch;
- anchor plate;
- helical shaft.
principle of operation and characteristics of movement parts Bendix
pinion drive with overrunning clutch serves to ensure that the work the starter motor does not match the frequency of the engine speed.Both parts are rotated simultaneously, together with the armature shaft in only one direction.In others, they rotate freely.Moreover, this indication is independent of the state of the armature, which is arranged in such items as a starter.Bendix on domestic production of cars Volga is a roller tool that works on the principle of the wedge.When the device is actuated, the armature turns transmitted clutch outer race.External holder at the same time begins to rotate relative to the inner.Often the latter part remains stationary while the Bendix because the pinion is in connection with the flywheel of the engine inoperative.Under the influence of the force of friction rollers are moved to the narrowest part of the wedge space, thereby separating the two clips together.Thus, Bendix starter actuates anchor while simultaneously actuating the handwheel.
It should also be noted that this item has in its design a special spring retractor relay and inclined slots.They serve to Bendix starter out of the compound with a wreath of a flywheel.These parts are mounted on the shaft of the armature.As it goes towards the hub motor.
Vulnerable parts
As any other mechanism, Bendix starter has its weaknesses.And are they in increased wear and gear drive flywheel.When engaging both parts strongly subjected to impact, therefore, as a rule, their life span is small.
Application
Today Bendix starter is widely used in the automotive industry, namely, the electric starter vehicles.Also, this piece is installed on some aircraft.
