Description

The Bicycle pulley fluted disc of improvement

Technical field

The utility model particularly relates to the Bicycle pulley fluted disc of improvement about a kind of bicycle assembly.

Background technology

At present, in bicycle transmission system, except that the conventional chains transmission, also has mode in addition with pulley drive, according to engineering verification, pulley drive system has transmission and stablizes, is difficult for taking off chain, and at a high speed not landing, high efficiency, life-span length, save space, low noise, speed ratio are big, lightweight and need not to add plurality of advantages such as lubricant can keep totally.

Time rule belt holder in the belt sheave structure between a large fluted disc and a small tooth plate, wherein, as shown in Figure 1, the large fluted disc structural representation of known Bicycle pulley group, this large fluted disc 1 is provided with denture 11 in all sides, is formed with stopper 12 in denture 11 1 sides; And be to fill up large fluted disc 1 because of cooperating the structure design drop that body construction designs and lightweight requirements produced, convex with more than one connecting support 13 in denture 11 other one in addition, and at this in conjunction with a catch 14, advise belt during the common limit block of this catch 14 and aforesaid stopper 12 and deviate from.

But, find in practice, the operation of this large fluted disc 1 is at the machined into dish after one's death, must process this connecting support 13 with milling machine in addition, that is to say that it is to take the secondary processing mode to make, under the high situation of wage now, except that cause work programme loaded down with trivial details, more therefore cause manufacturing cost high.

And small tooth plate also has identical problem, and the small tooth plate of known Bicycle pulley is common to be with the additional steel liner of a fluted disc seat, but the baffle ring body that the rule belt is deviate from during in conjunction with a block in multiple spot riveted joint mode again; Must distinguish repeatedly processing but this kind formed its member of structure, be made up again, and it is to make in multiple spot riveted joint mode, more make manufacturing cost reduce.

The problems referred to above remain to be overcome solution.

The specific embodiment

See also shown in Figure 2ly, the large fluted disc structural representation that it is the Bicycle pulley fluted disc embodiment of the utility model improvement comprises:

Large fluted disc 2, it is provided with denture 21 in all sides;

Be provided with integrated stopper 22 in these denture 21 1 sides;

At these large fluted disc 2 dentures 21 other at least one combined holes 23 that are preset with;

At least one catch body 3 is provided with a portion 31 at the one end, and this one 31 is provided with combined hole 32.

This catch body 3 is with corresponding large fluted disc 2 structures of the shape of its one 31, and in bolt 33 mode that is spirally connected, and makes its combined hole 32 be incorporated into combined hole 23 places of large fluted disc 2, deviates from so that advise belt during with the common limit block of aforesaid stopper 22; The scheme drawing of rule belt 5 when Fig. 3 hangs for the Bicycle pulley fluted disc embodiment large fluted disc of the utility model improvement is attached.

Because, the combined hole 23 of this large fluted disc 2 only is simple perforation processing, can omit the known configurations that discloses the front also needs further to be processed to form with milling machine the loaded down with trivial details work programme of connecting support, this catch body 3 then is merely with the fast a large amount of processing and manufacturings of lathe, therefore, the processing of whole large fluted disc 2 is able to effective simplification, cuts down finished cost.

And subsidiary pointing out, when in that denture 21 1 sides are not one-body molded when stopper 22 is arranged, then in combined hole 23 bilateral symmetry of large fluted disc 2 or asymmetric in conjunction with described catch body 3, the rule belt is deviate from during common limit block, still is one of possible embodiment of the utility model.

Continuation is with reference to figure 4, and it is the small tooth plate STRUCTURE DECOMPOSITION scheme drawing of the Bicycle pulley fluted disc embodiment of the utility model improvement, and this small tooth plate 4 comprises:

Fluted disc body 41, it is the ring body shape, is provided with denture 411 in its all side;

Interior ring at this fluted disc body 41 is formed with internal thread part 413;

Be provided with integrated stopper 412 in these denture 411 1 sides;

Catch body 42, it is the ring body shape, is provided with most protuberances 421 that combine usefulness with axletree in its ring body, then is formed with external thread part 422 again outside ring body;

Be provided with catch 423 at these catch body 42 1 side rings.

As shown in Figure 5, this catch body 42 is screwed together in the internal thread part 413 of this fluted disc body 41 rings with its external thread part 422, and rule belt 5 is deviate from (scheme drawing that Fig. 6 advises belt during for the attached extension of Bicycle pulley fluted disc embodiment small tooth plate of the utility model improvement) during by the common limit block of the catch 423 of the stopper 412 of these fluted disc body 41 1 sides and catch body 42; And time rule belt 5 is in the clockwise direction under the twirl in the driving, more can improve the tightness degree that screws togather of this fluted disc body 41 and catch body 42, makes the structural strength of combination obtain to promote and ensures.

And the utility model comprises large fluted disc 2 or small tooth plate 4, forms mode by its structure of improvement, reaches the purpose of simplifying the processing and manufacturing flow process, solves the problem that the existing need of known configurations are repeatedly processed, manufacturing cost can't reduce fully.

The above; only be the utility model possibility embodiment; can not limit the scope that the utility model is implemented with this; be that every simple equivalent of being done according to the utility model claims and utility model description changes, modifies and displacement, all should belong to the claimed scope of the utility model.
