Abstract
A single cylinder diesel engine plenum device relates to a diesel engine fitting including a pressure unit installation set, a power drive pulley, a follower pulley, and compressor wheels. A major diameter power drive pulley arranged on the power take off part of the single cylinder diesel drives the small diameter follower pulley through leather belts. The follower pulley is connected to a compressor impeller by a long axis. The long axis is arranged in the sleeve pipe through the bearings on two ends. The sleeve pipe is arranged on the plenum device installing seat directly or through a leather belt tension kickstand. A gas compressor end closure tight fit is covered on the sleeve pipe and tightened by holding screws. Sealing rings are arranged between the axle sleeve inner holes near the gas compressor and the long axis. A bearing positive stop sleeve with an inner thread screw barrel structure is socket jointed on the other end of the axis sleeve. The utility model has advantages of that the operation is reliable, the structure is simple, the manufacturability is good, and the practicability is strong.

The model utility content:
The technical problems to be solved in the utility model provides a kind of belt transmission of can effectively utilizing and obtains power, reliable operation, simple in structure, practical single cylinder diesel air inlet boosting device from diesel engine.
The technological scheme that solves the problems of the technologies described above is: a kind of single cylinder diesel air inlet boosting device, by being contained in the diesel powered output terminal---the bent axle or the drive pulley on the flywheel that are single cylinder diesel obtain the gas compressor driving force from diesel engine, comprise supercharging device fitting seat, drive pulley, drivign belt, driven pulley and compressor impeller, the major diameter drive pulley that is contained on the single cylinder diesel clutch end drives the driven pulley of minor diameter through belt, and driven pulley connects with compressor impeller by major axis; Major axis passes through the Bearing Installation at two ends in the axle sleeve the inside, axle sleeve directly or by the belt tension support is installed on the supercharging device fitting seat, gas compressor end cap drive fit is enclosed within on the axle sleeve and is fastening by Cock screw, between near the axle sleeve endoporus of gas compressor one side and major axis seal ring is arranged.
Further technological scheme of the present utility model is: the belt tension support that adjusting screw is housed is hinged to by hinging shaft and constitutes hinge belt tension mechanism on the supercharging device fitting seat, and axle sleeve is installed on the belt tension support.
Because adopt technique scheme, the beneficial effect that the single cylinder diesel air inlet boosting device of the utility model has is: the package unit reliable operation, simple in structure, good manufacturability, practical.
Hinge belt tension mechanism particularly is housed on the utility model single cylinder diesel air inlet boosting device, can makes belt tension by tightening the relative position between adjusting screw adjusting driven pulley and the drive pulley, thereby guarantee the reliability of transmission.
Below, the technical characteristics to the single cylinder diesel air inlet boosting device of the utility model is further described in conjunction with the accompanying drawings and embodiments.
Description of drawings:
The structural representation (plan view) of Fig. 1 the utility model single cylinder diesel air inlet boosting device;
The A-A sectional view of Fig. 2-Fig. 1.
Among the figure: 1-drive pulley, 2-belt, 3-driven pulley, 4-bearing stop collar, 5-bearing spacer, 6-bearing, 7-major axis, 8-belt tension support, 9-axle sleeve, 10-Cock screw, 11-gas compressor end cap, 12-compressor impeller, 13-compressor housings, 14-diesel engine intake pipe, 15-seal ring, 16-supercharging device fitting seat, the 17-adjusting screw, 18-backing plate, 19-hinging shaft.
Embodiment:
Embodiment one:
A kind of single cylinder diesel air inlet boosting device, by being contained in the diesel powered output terminal---the bent axle or the drive pulley on the flywheel that are single cylinder diesel obtain the gas compressor driving force from diesel engine, comprise supercharging device fitting seat 16, drive pulley 1, drivign belt 2, driven pulley 3 and compressor impeller 12, the major diameter drive pulley 1 that is contained on the single cylinder diesel clutch end drives the driven pulley 3 of minor diameters through belt 2, and driven pulley 3 connects with compressor impeller 12 by major axis 7; Major axis 7 is installed in axle sleeve 9 the insides by the bearing 6 at two ends, axle sleeve 9 is installed on the supercharging device fitting seat 16 by belt tension support 8, the belt tension support 8 that adjusting screw 17 is housed is hinged to by hinging shaft 19 and constitutes hinge belt tension mechanism on the supercharging device fitting seat 16, gas compressor end cap 11 drive fits are enclosed within on the axle sleeve 9 also fastening by Cock screw 10, between near axle sleeve 9 endoporus of gas compressor one side and major axis 7, seal ring 15 is housed, is socketed with a bearing stop collar 4 with internal thread screw bushing structure at the other end of axle sleeve 9.
Above-mentioned mode of execution is one of preferred forms of the present utility model;
A kind of conversion as the utility model embodiment, also can be without the hinge belt tension mechanism of belt leather band tensioning support 8, and adopt other forms of belt tension mechanism, or do not have belt tension mechanism and axle sleeve 9 is directly installed on the supercharging device fitting seat 16, but were it not for belt tension mechanism, transmission efficiency is reduced.
As another conversion of the utility model embodiment, also can adopt other limit structure without bearing stop collar 4 at the other end of axle sleeve 9.
Working procedure: the drive pulley 1 that is contained on the single cylinder diesel clutch end (being the bent axle or the flywheel of single cylinder diesel) drives driven pulley 3 through belt 2, driven pulley 3 carries out supercharging by the air inlet that major axis 7 drives 12 pairs of single cylinder diesels of compressor impeller, air after the supercharging is sent to the single cylinder diesel cylinder by diesel engine intake pipe 14, realizes the single cylinder diesel super charge.
