Abstract

The utility model relates to a planetary differential gearing which is used for equipment for roll forming of circular rims. In addition, the utility model is a core part of the equipment for roll forming of the circular rims. The utility model is composed of a gear (1), a rotating arm (2), center wheels (3) and (9), a shaft (4), a gear (5), planetary wheels (6) and (10), etc. Dynamic force can be divided into two paths to be output simultaneously after the dynamic force is input from the gear (1) by the rotating arm (2), wherein, one path is output from the center wheel (3) and is transmitted out by the gear (5), and the other path is output from the center wheel (9) and is transmitted out by a gear (8). Under differential functions, although the diameters of two rolling wheels are different, the linear velocity of the surfaces of the rolling wheels can be same. Thereby, the surface of the circular rims, which are rolled can becaome smooth and clean, and have uniform thickness.

Description

Planetary differential gearing

The utility model planet differential device is used for wheel rim rolling forming equipment.

At present, China's wheel rim rolling forming equipment is in the process of wheel rim rolling forming, after the constant rotational speed input, owing to the diameter difference of upper and lower two rolling wheels, so the linear velocity on rolling wheel surface is also different.Cause wheel rim to produce phenomenons such as plucking, coarse and thickness be irregular, the technical requirements that does not reach the wheel rim part through the surface of roll extrusion place.

Disadvantage in view of above prior art existence, the utility model planet differential Design of device task is: a kind of device of design in wheel rim rolling forming equipment, make rolling wheel under the different situation of diameter, importing a constant rotational speed, also to reach linear resonance surface velocity automatically identical, thereby make bright and clean through the rim surface behind the rolling forming, thickness is even, reaches the technical requirements of wheel rim part.

The utility model planet differential device is a housing shape structure.From accompanying drawing 1 as can be known: (1) gear; (2) pivoted arm; (3), (9) central gear; (4) axle; (5) gear; (6), (10) planet wheel; (7), (11) axle; (8) gear.

The gear (1) of the utility model planet differential device, pivoted arm (2) and central gear (3), (9) are on coaxial line.Central gear (3), gear (5) is the slip edge joint with axle (4), central gear (9) with the axle (4) for fixedlying connected, and be slidingly connected with pivoted arm (2), planet wheel (6), (10) axle on (7), (11) be installed on the pivoted arm (2), planet wheel (6), (10) and pivoted arm (2) all by the axle (7), (11) be slidingly connected, central gear (3), (9) with planet wheel (6), (10) velocity ratio is 2 to 1, and with central gear (3), (9) engagement, its planet wheel (6), (10) can be around axle (7), (11) rotation can be revolved round the sun around axle (4) with pivoted arm (2) again.

The advantage of the utility model planet differential device: simple in structure, easy to maintenance, reliable operation.It is " heart " part of wheel rim rolling forming equipment.After adopting this device, can make that wheel rim part surface through roll extrusion is bright and clean, thickness is even, meets the technical requirements of wheel rim part.

Fig. 1 is a planet differential device transmission schematic representation.

Below in conjunction with Fig. 1 the utility model working procedure is described further: gear (1) is fixedlyed connected with pivoted arm (2), pivoted arm (2) and central gear (3), (9) for being slidingly connected, and on same axis, planet wheel (6), (10) with pivoted arm (2) also for being slidingly connected, when power is imported by gear (1), through pivoted arm (2), planet wheel (6), (10) and central gear (3), (9), make planet wheel (6), (10) can rotation can revolve round the sun around axle (4) again, make motion respectively from gear (8) and gear (5) output, under the effect of differential function, the rotating speed of gear (5) output can be regulated automatically, it is identical to reach the required two rolling wheel linear resonance surface velocities of wheel rim rolling forming, reach bright and clean through the wheel rim part surface of roll extrusion, thickness is even, meets the technical requirements of wheel rim part.
