Abstract
The utility model discloses a tensioning fan shaft part structure, which comprises a fan support base plate, a tensioning bolt, a clamp nut, a fan support connecting plate and a fan shaft part. The fan support base plate is fixed on a machine body, and the fan shaft part is fixed on the fan support base plate through the fan support connecting plate. A fixing screw hole is required to be a U-shaped long-hole structure, and the fan shaft part moves upwards through the tensioning of the tensioning bolt so as to tension a belt. The tensioning fan shaft part structure removes a separate tensioning wheel, is simple and easy to operate, saves very large space for arrangement of a whole machine, drives a belt wheel to directly drive the fan shaft part, and is more reliable in structure.
Description
Technical field
The utility model relates to a kind of easy tensioning fan shaft modular construction, has saved arrangement space greatly, can be widely used in mechanical industries such as automobile, motor.
Background technique
At present, the application of diesel engine is increasingly extensive, relates to commercial car and passenger car two classes, and the layout of a front end train big bottleneck of motor often mainly is that the space is limited, and train is difficult to arrange.
Generally by the tension wheel structure auto-tensioning, the structure more complicated needs the space big to the fan shaft parts, is difficult to arrange; Therefore, need use a kind of simple in structure, space-saving tension structure.
Summary of the invention
The purpose of this utility model is to provide a kind of fan shaft parts to be fixed on the blower tray backing plate by the blower tray connecting plate, screw on the blower tray connecting plate is a U type hole slotted hole, there is screw that tensioning bolt is installed above, the boss of a bolt is arranged on the blower tray backing plate.Blower tray connecting plate and fan shaft parts move up, realize tensioning function and the compacter fan shaft belt pulley transfer mode in space, overcome the deficiency of arranging on the fan shaft belt pulley train space, the tensioning mode is more easy, satisfies the demand of engine wheel system.
The technical solution of the utility model is such: a kind of tensioning fan shaft modular construction, comprise blower tray backing plate, tensioning bolt, tightening nut, blower tray connecting plate, fan shaft parts, it is characterized in that between fan shaft parts and the blower tray backing plate blower tray connecting plate being arranged, blower tray connecting plate side has screw, and the screw the inside is equipped with tightening nut and tensioning bolt.
The fan shaft parts install on the blower tray connecting plate, and the blower tray connecting plate installs on the blower tray backing plate with bolt, tighten tensioning bolt end roof pressure blower tray plate, fix with tightening nut, tighten the construction bolt on the blower tray connecting plate.
The blower tray backing plate is fixed on the body, and the screw of blower tray connecting plate is a U type hole slotted hole, and the boss of bolt is arranged on the blower tray backing plate.
The utility model has the advantages that: between fan shaft parts and the blower tray backing plate blower tray connecting plate is arranged, U type slotted hole is arranged on the blower tray connecting plate, on the blower tray backing plate supporting boss is arranged, on the blower tray connecting plate screw is arranged, the screw the inside is equipped with tightening nut, tighten construction bolt on the blower tray connecting plate with tensioning bolt, reach the purpose of idler.Simple in structure, arrangement space is little, and is easy to operate.
Description of drawings
It is such that structure of the present utility model constitutes:
Fig. 1 is the main sectional view of looking of a kind of tensioning fan shaft of the utility model parts overall structure assembling.
Fig. 2 is a kind of tensioning fan shaft of the utility model parts overall structure assembling stereogram.
Among Fig. 1～Fig. 2, blower tray backing plate (1), tightening nut (2), tensioning bolt (3), blower tray connecting plate (4), fan shaft parts (5).
Embodiment
It is such that the utility model is implemented, and with reference to accompanying drawing 1～Fig. 2, as shown in the figure, a kind of tensioning fan shaft of the utility model modular construction can make the fan shaft belt pulley need not the Idle wheel tensioning, arranges more compact.Comprise blower tray backing plate, tensioning bolt, tightening nut, blower tray connecting plate, fan shaft parts.The fan shaft parts are fixed on the blower tray backing plate by the blower tray connecting plate, screw on the blower tray connecting plate is a U type hole slotted hole, and above have and attack the screw of wearing, tensioning bolt is contained in this hole, and the boss of a bolt is arranged on the blower tray backing plate.
In the process that tensioning bolt is tightened, blower tray connecting plate and fan shaft parts are moved up, realize the function of tensioning.Between fan shaft parts (5) and the blower tray backing plate (1) blower tray connecting plate (4) is arranged, screw on the blower tray connecting plate (4) is a U type hole slotted hole, a supporting boss is arranged on the blower tray backing plate (1), blower tray connecting plate (4) upper end has a screw, and the screw the inside is equipped with tightening nut (2) and tensioning bolt (3); Fan shaft parts (5) install to earlier on the blower tray connecting plate (4), then fan rack connecting plate (4), install on the blower tray backing plate (1) with bolt, do not tighten earlier construction bolt, by the mode of tightening tensioning bolt (3) belt tension is arrived correct position, fixing with tightening nut (2), tighten the construction bolt on the blower tray connecting plate (4) again, thereby reach the purpose of tightening belt.
It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technological scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technological scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
