Abstract
The utility model relates to a poly V-belt tensioning wheel. The poly V-belt tensioning wheel comprises a hexagonal fixed wheel axle, belt pulleys and a square fixed wheel axle, wherein the belt pulleys are connected to the hexagonal fixed wheel axle through bearings, the square fixed wheel axle is connected inside the hexagonal fixed wheel axle in a threaded mode, balancing sleeves are arranged between the hexagonal fixed wheel axle and the square fixed wheel axle, a regulation hole which is connected with a threaded rod is formed in the square fixed wheel axle, and the belt pulleys are multi-wedged pulleys. The poly V-belt tensioning wheel is simple in structure, low in cost, capable of effectively tensioning a belt, dustproof and long in service life.
Description
Technical field
The utility model relates to the tension device field, relates in particular to a kind of poly Vbelt Idle wheel.
Background technique
In the Modern Engine assembly, each annex of motor is all that the transfer motion power of accepting the bent axle driving wheel by being arranged on belt pulley on axle carries out work, development along with technology, the selection of dynamo belt is also more and more, due to poly Vbelt, to have vibrations little, rapid heat dissipation, smooth running, the characteristics of lightweight robust thin, be widely used now the generator in driving engine pack, air condition compressor, water pump, the engine accessory power ratings such as fan, but need certain pretightening force while using poly Vbelt, poly Vbelt is after long-time running is used, length can be extended gradually and be caused poly Vbelt tension force to descend, occur that the phenomenon of skidding appears in each wheel that poly Vbelt drives, affect the normal operation of cluster engine.
Summary of the invention
The purpose of this utility model is to provide a kind of poly Vbelt Idle wheel, solve because length after the long-time running of poly Vbelt can elongation gradually cause poly Vbelt tension force to descend, and then each wheel that causes poly Vbelt to drive skids and affects the problem of each wheel speed.
For achieving the above object, the technical solution of the utility model is: a kind of poly Vbelt Idle wheel, comprise fixedly wheel shaft of hexagonal, belt pulley and square fixedly wheel shaft, described belt pulley is connected to hexagonal fixedly on wheel shaft by bearing, and described square fast pulley male thread is connected to hexagonal fixedly in wheel shaft, at hexagonal fixedly wheel shaft and the square balance set that fixedly is provided with between wheel shaft, be provided with an adjustment hole be connected with screw rod on described square fixedly wheel shaft, described belt pulley is many wedge wheels.
Further, described belt pulley axial direction is provided with the dust cover slot, also comprises a dust cover, and described dust cover is arranged on hexagonal fixedly on wheel shaft, and the outer rim of dust cover is inserted the dust cover slot of belt pulley.
Idle wheel of the present utility model, can reach the purpose of tightening belt in the position of screw rod by regulating square fixedly wheel shaft, the dust cover design of adding, can effectively prevent that dust from entering bearing, extend the working life of bearing, adopt the design of many wedge wheels simultaneously, can be widely used in the engine pack equipment that uses poly Vbelt, poly Vbelt Idle wheel of the present utility model, simple in structure, with low cost.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of poly Vbelt Idle wheel, comprise fixedly wheel shaft 1 of hexagonal, belt pulley 2 and square fixedly wheel shaft 3, belt pulley 2 is connected to hexagonal fixedly on wheel shaft 1 by bearing 4, and bearing 4 is fixed by the jump ring of front end and the shelves shell of rear end, square fixedly wheel shaft 3 is threaded in hexagonal fixedly in wheel shaft 1, at hexagonal fixedly wheel shaft and the square balance set 5 that fixedly is provided with between wheel shaft, be provided with an adjustment hole be connected with screw rod 6 on square fixedly wheel shaft 3, belt pulley is many wedges wheels.
During use, can use spanner to regulate the position of square fixedly wheel shaft on screw rod, reach the purpose of tensioning poly Vbelt.
