Definitions
- the present invention relates to a gear coupling capable of transmitting a rotational force from a drive shaft to a driven shaft even when at least one of the drive shaft and the driven shaft moves. is there. Troublesome technology
- a gear joint known as a flexible gear joint has been used, for example, in a drive device such as a railway vehicle, an automobile, and a rolling device to connect a drive motor and a reduction gear cover. .
- Japanese Unexamined Patent Publication No. 47-14804 discloses a gear joint for connecting a drive motor and a reduction gear device in a railway vehicle drive device.
- 5 and 6 are side sectional views showing the interior of a conventional flexible gear coupling similar to that described in the above-mentioned publication, with a part cut away. In Figs.
- the drive axis 10 of the free space a, a 'and the axis of the driven axis 10' As shown in Fig. 5, the fixed stoppers 1, 1 'when the axial centers of the external gears 3a, 3a' and the internal gears 5a, 5a 'coincide with each other are shown in Fig. 5. And the distance between the center plates 2 and 2 '.
- the distance between the pinions 3 and 3 ′ is relative to the sleeves 5 and 5 ′ from the position in FIG. It is the distance that can be moved to the same distance as the maximum allowable displacement.
- the maximum allowable displacement distance is a distance determined by the design specification of the arrangement structure of the motor (not shown) and the reduction gear (not shown).
- the drive shaft 10 rotates, and the external gear 3 a of the pinion 3 and the internal gear 5 a of the sleeve 5 babble and the sleeve 5
- the sleeve 5 ′ flanged to the sleeve 5 rotates, and the internal gear 5 ′ a of the sleeve 5 ′ and the external gear 3 a ′ of the pinion 3 ′ are driven together with the babies.
- FIG. 6 shows an example in which the drive shaft 10 and the driven shaft 10 'have been moved by an external force from the state of FIG. 5, and the drive shaft 10 and the driven shaft 10' This is the case when the robot moves in the directions d and d 'in FIG.
- the fixed stoppers 1, 1 ′ are close to or in contact with the center plates 2, 2 ′, and the dust stoppers 4, 4, and the end covers 6, 6 ′ remain in contact with each other. . Therefore, the dust does not enter the inside of the flexible gear joint from the outside, and the grease 12 does not leak from the inside of the flexible gear joint to the outside.
- FIG. 7 and FIG. 8 are side sectional views showing a flexible gear joint having a long maximum allowable displacement distance by cutting out a part thereof. 7 and 8 are the same as those in FIG. 5 except for the maximum allowable displacement distance, and a description thereof will be omitted.
- the length of the sleeves 5, 5' in the axial direction may be increased as shown in FIG. . That is, free space b, b 'shown in FIG.
- FIG. 7 may be provided which is longer in the direction of the drive shaft 10 and driven shaft 10' than the free spaces a, a 'shown in FIG. .
- the driving force is smoothly increased. It is transmitted from 10 to the driven shaft 10 '.
- dust may enter the inside of the flexible gear joint from the outside, and grease 12 may leak from the inside of the flexible gear joint to the outside.
- FIG. 8 shows a state in which the positions of the drive shaft 10 and the driven shaft 10 ′ do not change from the state of FIG. 7, and the core plates 2, 2 ′, the sleeves 5, 5, and the end cover 6.
- the sleeves 5, 5' may move the maximum allowable distance. Therefore, the fixed stopper 1 approaches or comes into contact with the center plate 2, and the dust stopper 4 'and the end cover 6' separate from each other. In addition, there is a problem that a space e 'is formed between the dust keeper 4 and the end cover 6'. Also, at this time, the sleeves 5 and 5 ′ may move more than necessary, and large vibration and resonance may occur.
- Fig. 5 is used to make the explanation easier to understand. It performs the same function as the fixed stoppers 1 and 1 'in FIG. 5, and replaces the fixed stoppers 1 and 1' with the center plates 2 and 1 '.
- a panel was inserted between 2 'and pinions 3 and 3' to constantly press the pinions 3 and 3 'against the drive shaft 10 and the driven shaft 10'.
- Other configurations are shown in Fig. 5 and ⁇ . In this case, the panel was placed between the center plates 2 and 2 'and the pinions 3 and 3', so a heavy panel was needed.
- the center plate is also used during normal operation in which no external force acts on the drive shaft 10 and the driven shaft 10 '.
- the spring force acts on 2, 2 'and pinions 3, 3', and the panel may vibrate and resonate. Therefore, smooth driving force may not be transmitted from the drive shaft 10 to the driven shaft 10 ′.
- the present invention has been made to solve the above-described problems, and suppresses the unnecessary movement of the sleeve even when the maximum allowable displacement distance of the driving shaft and the driven shaft is long, It is an object of the present invention to provide a gear coupling capable of smoothly transmitting a driving force.
- Another object of the present invention is to provide a flexible gear coupling that has a long allowable maximum displacement between a driving shaft and a driven shaft, can transmit a smooth driving force, and has a low possibility that the inside communicates with the outside.
- a flexible gear coupling includes a drive shaft, a pinion fixed to the drive shaft and having an external gear, a sleeve having an internal gear that mates with the external gear, and one end of the sleeve.
- the pinion can move the maximum displacement allowable distance by its own air relative to the sleeve, and is driven from the drive shaft to the driven shaft.
- the drive unit is configured so that the leave can move in a predetermined free space relative to the pinion, and when a force smaller than the maximum external force acts on the drive shaft or the driven shaft, the pinion is moved to a predetermined position.
- a movable stopper for restricting the movement of the sleeve is provided so as to move a distance shorter than the maximum allowable displacement relative to the sleeve. Even if the maximum allowable displacement of the motor is long, the movement of the sleeve more than necessary is suppressed, and smooth driving force can be transmitted.
- the arrangement is made such that contact between the end cover provided on the sleeve and the dust trap provided on the pinion is maintained. Therefore, it is unlikely that the inside communicates with the outside.
- the movable stopper has a simple structure because it has a panel held by the drive shaft and a buffer body whose one end is in contact with the panel and whose other end faces the center plate. Production and assembly is easy.
- the allowable maximum distance is taken into account when the drive shaft 10 and the driven shaft 10 'are inclined.
- the maximum allowable displacement of a flexible gear joint in a railway vehicle drive unit is several tens of mm in the axial direction of the drive shaft 10 and the driven shaft 10 'based on the state shown in Fig. 1. This value is determined by a motor (not shown) and a motor (not shown) (depending on the specification arrangement of the wheels and the like.
- C, c ′ is relatively free between the pinions 3 and 3 ′ and the sleeves 5 and 5).
- the axial lengths of the drive shaft 10 and the driven shaft 10 ′ of the free spaces c and c ′ are the external gear 3.
- the movable stoppers 8 and 8 ' are used as both the drive shaft 10 and the driven shaft 10'.
- the configuration provided is explained, but it may be configured to be provided on only one shaft.
