Abstract
The utility model relates to an air pump transmission mechanism of an engine. An idle gear is driven by a crankshaft timing gear of the engine and drives a camshaft gear which in turn drives an air pump transmission gear to transmit power to the air pump transmission gear, thereby driving an air pump to work. Since power transmission of the air pump assembly is carried out through intermeshing of gears, the transmission efficiency is high. Moreover, the air pump transmission mechanism is compact in structure, reliable in work and ling in service lifetime.
Description
Technical field
The utility model relates to a kind of engine air pump drive mechanism.
Background technique
At present, motor because of joining vehicle and machinery needs be equipped with air pump (air compressor).Air pump brings transferring power with the V that the rubberized canvas material is processed mostly; The work of driving air pump; The path is: the power of bent axle is with 13 to pass to air pump belt wheel 12 and drive air pump 11 work by crank pulley 14 through V; Or the power of bent axle passes to water pump pulley by crank pulley through V band, passes to air pump belt by water pump pulley through the V band again and takes turns the air pump work that drives.Because V band is influenced by material characteristics, in use for some time, the length that can be stretched causes the V band to skid and causes the air-pump inflating decrease in efficiency, need the user to make regular check on the degree of tightness of adjustment V band, and the life-span of V band is shorter, has increased user cost.
Summary of the invention
Influenced by material characteristics for solving the V band, in use for some time, the length that can be stretched causes belt slippage and causes the air-pump inflating decrease in efficiency, needs the user to make regular check on the degree of tightness of adjustment belt.The utility model provides a kind of DENG air pump driving mechanism.
The concrete structure scheme is following:
A kind of engine air pump drive mechanism comprises air pump assembly 7, gear chamber 2 and engine crankshaft 8,
Said in the gear chamber 2 of engine body 3 front ends, engine crankshaft timing gear 1, idle gear 4, camshaft gear wheel 5 gentle pump drive gears 6 are installed;
Said engine crankshaft timing gear 1 are installed in engine crankshaft 8 front ends, and are meshing with each other with idle gear 4;
Said idle gear 4 is installed in body 3 front-end faces through idle gear axle 9, and is meshing with each other with camshaft gear wheel 5;
Said camshaft gear wheel 5 is installed on the camshaft 10, and is meshing with each other with air pump driving gear 6;
Said air pump driving gear 6 directly is contained on the air pump bent axle, and above-mentioned gear is arranged in the gear chamber 2 of body 3 front ends, and 7 of air pump assemblies are directly installed on the gear chamber 2 through two bolts.
A kind of engine air pump drive of the utility model mechanism, the power of air pump because the air pump assembly is to be meshing with each other transferring power through gear, has the transmission efficiency height, compact structure, reliable operation, the advantage of long service life from the engine crankshaft timing gear.

Among the figure: 1-crankshaft timing gear, 2-gear chamber, 3-body, the lazy tooth of 4-, 5-camshaft gear wheel, 6-air pump driving gear, 7-air pump assembly, 8-bent axle, 9-idle gear axle, 10-cam, 11-air pump, 12-air pump belt wheel, 13-V band, 14-crank pulley.
Embodiment
As shown in Figure 1 a kind of engine air pump drive mechanism; Comprise air pump assembly 7, gear chamber 2 and engine crankshaft 8; In the gear chamber 2 of engine body 3 front ends, engine crankshaft timing gear 1, idle gear 4, camshaft gear wheel 5 gentle pump drive gears 6 are installed;
Said engine crankshaft timing gear 1 are installed in engine crankshaft 8 front ends, and are meshing with each other with idle gear 4;
Said idle gear 4 is installed in body 3 front-end faces through idle gear axle 9, and is meshing with each other with camshaft gear wheel 5;
Said camshaft gear wheel 5 is installed on the camshaft 10, and is meshing with each other with air pump driving gear 6;
Said air pump driving gear 6 directly is contained on the air pump bent axle, and above-mentioned gear is arranged in the gear chamber 2 of body 3 front ends, and 7 of air pump assemblies are directly installed on the gear chamber 2 through two bolts.
When engine operation, engine crankshaft timing gear 1 drive idle gear 4, and idle gear 4 drives camshaft gear wheel 5, drive air pump driving gear 6 by camshaft gear wheel 5 again, give air pump driving gear 6 with transmission of power, thereby drive 7 work of air pump assembly.
