Description

The improvement of locomotive continuous variable speed die clutch construction

Technical field

The utility model relates to locomotive continuous variable speed clutch configuration, particularly a kind of improvement of locomotive continuous variable speed clutch configuration, the mat bearing device, ball is isolated carrier up and down, spin friction power between the carrier is reduced, abrasion when reducing the spring rotation, and then reach and make clutch running is more smooth and easy doing that the time spent is lowered friction, with the purpose that prolongs its life-span.

Background technique

The locomotive continuous variable speed clutch of commonly seeing, shown in Figure 1A to 1C, clutch pack 100 mainly by last disc 110, down disc 120, constituted with hollow circular sleeve 130, bearing 140; Describedly go up that disc 110 is set on bearing 140 with following disc 120 and the end (being depicted as the lower end) that is positioned at bearing 140, but the mode of its two mat rotation is separated from each other or close (shown in Figure 1B and 1C) by figure; Hollow circular sleeve 130 is set in the bearing 140 of clutch pack, and places on the disc 110, and its lower end is a carrier 131, in order to bearing spring 150.Bearing 140 upper ends are for revolving axle 141, and mat bolt sheet 170 is established drive plate 160 with bolt.

Figure 1B, 1C are the schematic representation of the action of disc about in the of of the continuous variable speed clutch of commonly seeing; Wherein going up disc 110 is symmetric construction with following disc 120, is set on the bearing 140; When last disc 110 rotates (as shown in Fig. 1 C), last disc 110 is because the rotation of bearing 140 separates (shown in arrow among the figure) with following disc 120.

Fig. 1 D is the tectonic relationship figure of disc and spring up and down in the continuous variable speed clutch of commonly seeing; Shown in figure, spring 150 places in the carrying 131 of hollow circular sleeve 130, drives bearing 140 related rotation with the rotation of the carrier 131 of hollow circular sleeve 130 by drive plate 160.

The rotation of above-mentioned clutch has certain effect, still has deficiency when still implementing.

Locomotive is after long-term the use, spring is also through rotating many times, because in the above-mentioned clutch, spring 150 directly contacts with the carrier 131 of hollow circular sleeve, the long-term rotation down, make carrier 131 parts on spring 150 lower ends and the hollow circular sleeve 130 all produce heavy wear, and make the effect of clutch that the part of having some setbacks be arranged.

Moreover because above-mentioned spring 150 produces loss with tray 130, except the working life that influences clutch, the high heat that its friction is produced also causes the damage of other members easily.

Summary of the invention

The utility model aims to provide a kind of improvement of locomotive clutch structure; Between spring and disc, set up the ball bearing device,, reduce clutch and make the friction that the time spent produces, and then make the clutch running more smooth and easy, and reduce abrasion, and then increase the service life by the rolling of ball; This is first purpose of the present utility model.

According to the improvement of locomotive continuous variable speed die clutch construction of the present utility model, the mat ball is isolated tray up and down, and reduces friction between carrier and grinder consumption up and down; For this with the novel purpose again of analysing.

The improvement of locomotive continuous variable speed die clutch construction of the present utility model can reach and reduce friction and consume between carrier up and down in the clutch member, the effect that increases the service life effectively by the ball bearing device.

Embodiment

The improvement of locomotive continuous variable speed die clutch construction of the present utility model as shown in Figure 2, mainly comprises: a hollow circular sleeve 21-1, and in order to the bearing 14 of sheathed clutch, the end of described hollow circular sleeve 21-1 is carrier 21-2; Upper supporting disk 23 is a hollow annular disk body, wears bearing 14 and in order to bearing spring 15, the bottom surface of upper supporting disk 23 is that a ring-type is colluded groove 23-1 (as shown in Figure 3), when upper supporting disk 23 is set on the bearing 14, can hold ball 22; The ball 22 of suitable quantity on average places down on the carrier 21-2, and in order to isolate carrier up and down, its purpose is to do the time spent when clutch, i.e. the friction between the carrier on the spring 15 and hollow circular sleeve 21-1 is originally lowered in the rolling of ball 22.

Fig. 3 is in the structure of locomotive continuous variable speed clutch of the present utility model, up and down the structure cutaway view of disc, carrier and spring; Shown in figure, upper supporting disk 23 bottom surfaces, be a ring-type collude groove 23-1, its degree of depth is h1; The degree of depth of following carrier 21-2 is h2; When upper supporting disk 23 is set on the bearing 14, with following carrier 21-2 near the time, can be by the fixing ball 22 of the degree of depth of colluding groove 23-1 of upper supporting disk 23; Again by shown in this figure, the diameter D of ball 22 is greater than colluding the summation of groove 23-1 degree of depth h1 with following carrier 21-2 degree of depth h2, therefore when upper supporting disk 23 be set in bearing 14 and with following carrier 21-2 near the time, can directly not contact by the diameter of ball 22 will isolate a spacing d between upper supporting disk 23 and following carrier 21-2; Therefore, when spring 15 rotated, mat was the shape of ball 22 circles, had reduced friction and consume when upper supporting disk 23 rotates, and then had prolonged the life-span of die clutch construction; The entire combination of its member is shown in Fig. 4.

Need Chen Mingzhe, the above is the preferable specific embodiment of the utility model, if conceive the change of being done according to the utility model, when the function that it produced does not exceed specification and the graphic spirit that is contained yet, all should in scope of the present utility model, close and give Chen Ming.
