A.overview
Hand starter is a new type, reliable energy efficient and
environmentally friendly diesel engine starting device. It USES
pure mechanical structure, except human outside, it does not
need to finish the work by other sources to process. It and
electricity motor, gas motors, such as hydraulic pressure motor
start-up mode, the difference is that it does not need to configure
a variety of other auxiliary equipments, such as batteries,
connecting cables, or storage tank, hydraulic accumulator, valve
and pipe and so on, maintenance is very simple. This hand
starter compact structure, operating safety, saving energy, no
environmental pollution, the use of cheap, and wide applicability. General industrial purposes, as backup machine or the ability to replace other appropriate the starting system can be used in generating set, mining machinery, Marine machinery, construction machinery, agricultural and irrigation machinery and other host above. As backup machine
brain-scanningexperiments with electric motor starter can also engine (installed together can pack double motors to the flywheel
shell). In addition, there are some special environment to avoid sparks, also need to be safe and reliable start-up mode, such as brain-scanningexperiments coal, sea oil drilling, certain chemicals factory, army, etc.
Second, hand the structure and working principle of starter
Hand starter for storage and release energy for medium, in spring coil springs can use volute in small starter, been limited, application in medium above the engine rarely used, are introduced in this paper with relatively reliable wing for the spring energy-storage medium, it can adapt to a starter medium, heavy, and even started tractors.powerful diesel engines needs.
Hand saucer reed energy storage by the four most starter assembly (institutions) composition, namely shaft institutions,
energy storage institutions, release mechanism and clutch institutions.
Shaft agencies are human input institutions, the major parts have disc shaft and transmission gears pay. It is human power conversion for spring potential only road. Its role is to determine
human shaft one of the shaft space and need, operation is convenient and comfortable Angle; Secondly it change to the
input torque swing, rotating axis of spindle of spring energy
storage with wing the axis; The third role is to limit the reversal of
the disc shaft; The first four role of spindle radial is the supporting
and axial thrust.
Energy storage mechanism is the main institutions, mainly
starter parts disc springs and spindle, they and the parts together
with cooperation, to realize the following functions, it is will the foregoing human input torque convert axial force, this force compression disc springs group, will the energy stored up; 2 be spring potential converts through the spindle output torque, form the dynamic. Drive diesel engine rotating
Disc springs is the starter of energy storage components, it is made of high-quality blank sheet metal or forging of conic
sections made the gasket type cutoff springs. Its features are: 1)
stiffness big, buffer shock absorption, and a strong ability to bear large with small deformation, reserves bigger energy load, suitable for axial dimensional demand is small occasions: 2) with variable stiffness properties, can by choosing the proper disc springs hO and deformation of pressure at ordinary times than, get the thickness t different characteristic curve; 3) use the same disc springs using different combination, can make spring characteristics in large scope changes. Can use DuiGe, composite combination, also can use composite different thickness and different slices of the number of combinations. The yogurt starter is different the diameter and thickness of multiple disc springs DuiGe add proper number of composite forming spring-set, adapt to different series of starter need. Figure 4 is a more pieces of DuiGe have to spring. 4) disc springs mature technology, reliable operation.
Release mechanism is the starter, main parts of control mechanisms are lifting lever assembly and release lever chain. The operator and release the rod through ascension stem operation. Accomplish two Operating lifting lever purpose is to let the release mechanism is in the ready state of energy, in this state, the spindle rotation will be limited, so that realize spring energy storage. The purpose is to release lever operation when
energy storage process finished, diesel engine, remove the need to start rotating restriction, and spindle release can be finished disc springs, spindle output torque, driving the flywheel driven gear rotating engine starting process.
Clutch institutions is to make starter and engine and
combining the movement off the institutions, mainly open parts are flywheel driven gear, with the help of spiral groove starter of
spindle, produce axial movement, when need when starting
diesel engine, the spindle rotation push it to the flywheel direction,
realization and fly cog laps of meshing; Conversely, when starter,
diesel engine beginning active work done, diesel engine flywheel
spinning of gear drive flywheel drive, and make its rotation axis
reverse move, take off along the open meshing gears.
Hand of starter easy operation. When diesel engine starting, first needs to ensure supply of diesel engine fuel system, pull the ascension of normal starter rod, to make release mechanism in energy storage preparing state, with dish to follow directions hands-on handle starter dish shaft rotation, achieve the required number of laps energy-storage appearance, then instructed to push in the direction of the pole, can complete release of diesel engine starting.
Three, hand of starter application parameters
Hand in land use starter has generator, Marine auxiliary engine etc above, a large amount of widely used before production test and application practice make this product reliability design concept and environmental protection and
energy saving design obtained user recognition, and will be used in more widely in the field, become the important guarantee safe
operation of diesel engine choice.
