Abstract

PURPOSE:To provide a V-belt shaped function on the belt shaped part and improve the performance of a transmission gear by means of a multiple-fluted belt in such a way that the belt-shaped part of the multiple-fluted belt is sectionally formed into truncated triangular shape, and the pulley on which the belt is wound around is made into a shape corresponding thereto. CONSTITUTION:In this transmission gear 1, the belt-shaped part 2 of a multiplefluted belt (A) is formed into equal leg truncated triangular shape at their sections of which upper part is larger than the lower part, and both lateral sides 2a of said belt-shaped part 2 are formed so as to be succeeded in the same plane flush with the outer lateral sides 3a, 5a of engaging fluted stripes 3, 5 on the outermost sides. Besides, both pulley grooves 7, 9 on the outermost sides of a pulley 10 which provides pulley grooves 7 to 9 correspond to said engaging fluted stripes 3 to 5 and the outer lateral sides of the belt- shaped part 2, and they are formed by extending more than the other pulley groove 8 outward in the radial direction. Thus, since the both lateral sides 2a of the belt-shaped part 2 of the belt (A) is also worked as the frictional faces with the pulley 10, lateral pressure ability is increased, transmissibility is increased, and durable life is improved, so that the performance is improved in various phases such that driving noise will become smaller, etc.

: ? When a load of Q Kq is applied, the slip ratio is 7.
%, the change in transmission horsepower was measured. Note that the multi-protrusion belts X type and A type used in the test are basically the same as the multi-protrusion belts X and A, except for the number of engaging protrusions. (Test Results) The test results are shown in Table 7. That is, it can be seen that the effect is greatest when the number of engaging protrusions is three, and as the number increases, the effect decreases. In addition, when the number of engagement protrusions is two, the buckling of the back becomes particularly large and the transmission capacity is reduced, so it is desirable to have three or more engagement protrusions. In addition, in Example 2.2, both sides 2 of the band-shaped portion 2

, 5a, but in addition, as is clear from the test results of v1) above, both side surfaces of the strip portion are formed continuously on the same plane as the outermost engagement protrusion. It can also be configured so that it is deviated by an angle of θ to 10% of the tip angle of the engagement protrusion. As a specific example, (Example 3) will be described next. (Example 3) The multi-protrusion belt D shown in FIG.
, 2a is the outer surface 3a of the outermost engagement protrusion 6, 5,
It is offset outward by an angle θ1 with respect to 5a, and the fifth
The multi-protrusion belt E shown in the figure has both sides 2a of the belt-shaped portion 2,
2a is offset inward by an angle θ2. In addition, multi-protrusion belt D. The basic structure of belt E is the same as that of multi-protrusion belt A shown in FIG. Moreover, it goes without saying that a side pressure member can be provided as in multi-projection bells B and C. Next, a test comparing the performance of multi-projection bells A, D, and E will be explained. Here, the belt upper angle α (see Figure 4) of multi-protrusion belts A, D, and E is 1.20, respectively.

For each of D and E, the change in slip ratio when the transmission horsepower was changed was measured. (Test Results) The test results are shown in FIG. 72. From FIG. 72, it can be seen that the smaller the belt upper angle σ is, the smaller the slip ratio is.
