Abstract
The utility model relates to an adjustable belt pulley. The adjustable belt pulley comprises a pulley body. A shaft hole is arranged in the middle of the pulley body. A shaft hole protection sleeve is arranged on the end portion of the pulley body arranged on the two sides of the shaft hole and the shaft hole protection sleeve protrudes outwards. A center line of an inner hole of the shaft hole protection sleeve and a center line of the shaft hole are coincident. The inner wall of the shaft hole is provided with a key groove along the shaft direction, and the key groove extends to the inner hole of the shaft hole protection sleeve. The outer wall of the shaft hole protection sleeve is provided with a bolt hole which is communicated with the inner key groove of the protection sleeve, the shaft hole and the inner key groove. The bolt hole is arranged on the shaft hole sleeve, the bearing and the belt pulley are connected in a key joint mode, then a fastening bolt can be screwed into the bolt hole and the tightness can be adjusted by the fastening bolt.
Description
Technical field
The utility model relates to a kind of adjustable straps wheel.
Background technique
Belt sheave structure in the past is simple, mainly is to be connected by key between belt pulley and the bearing, makes axle drive belt pulley and rotates together, occurs easily looseningly after a period of time between the key in the keyway and belt pulley using, and affects the precision of whole belt pulley.
The model utility content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of adjustable straps wheel is provided, solve in the past between the belt pulley and bearing easily loosening phenomenon.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of adjustable straps wheel, comprise wheel body, described wheel body middle part has axis hole, the wheel end of body of described axis hole both sides is provided with the axis hole sheath of outside projection, the center line of the endoporus of described axis hole sheath and the central lines of axis hole, the inwall of described axis hole is provided with keyway vertically, described keyway extends to the endoporus of axis hole sheath, offers the bolt hole that communicates with sheath axis hole interior spline on the outer wall of described axis hole sheath.
The beneficial effects of the utility model are: a kind of adjustable straps wheel is provided, by at the axis hole sheath bolt hole being set, can be by in bolt hole, screwing in clamping bolt after key is connected between bearing and belt pulley, by clamping bolt regulate and key between degree of tightness.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the structural representation of belt pulley;
Wherein: 1, wheel body, 2, the axis hole sheath, 3, keyway, 4, bolt hole.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic representation that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
A kind of adjustable straps wheel as shown in Figure 1, comprise wheel body 1, wheel body 1 middle part has axis hole, wheel body 1 end of axis hole both sides is provided with the axis hole sheath 2 of outside projection, the center line of the endoporus of axis hole sheath 2 and the central lines of axis hole, the inwall of axis hole is provided with keyway 3 vertically, and keyway 3 extends to the endoporus of axis hole sheath 2, offers the bolt hole 4 that communicates with sheath axis hole 2 interior splinies 3 on the outer wall of axis hole sheath 2.
By at axis hole sheath 2 bolt hole 4 being set, can be by at bolt hole 4 interior screw-in clamping bolts after key is connected between bearing and belt pulley, by clamping bolt regulate and key between degree of tightness.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this model utility technological thought, carry out various change and modification fully.The technical scope of this model utility is not limited to the content on the specification, must determine its technical scope according to the claim scope.
