As Fig. 3 (a) and shown in Figure 4, be 2 identical shaped jut 10a, 10b that oval-shaped pin constitutes for example by the cross section being provided with at a high speed with the inner peripheral surface of sliding component 3.At this, as shown in Figure 4, jut 10a, 10b are arranged on the different position of axial (left and right directions of Fig. 4) of ball screw 5, in addition, shown in Fig. 3 (a), with in the sectional view of sliding component 3, jut 10a and jut 10b are arranged on this and use at a high speed on the centrosymmetric position of sliding component 3 at a high speed.For jut 10a and handed over the 10b of portion ball screw 5 axially on the relative position relation aftermentioned.
As Fig. 3 (a) and shown in Figure 4, being provided with the inner peripheral surface of sliding component 4 at low speed is 2 identical shaped jut 11a, 11b that oval-shaped pin constitutes by the cross section for example.With the situation with sliding component 3 is identical at a high speed, as shown in Figure 4, jut 11a, 11b are arranged on the axial different position of ball screw 5, in addition, shown in Fig. 3 (b), with in the sectional view of sliding component 4, jut 11a and jut 11b are arranged on this low speed and use on the centrosymmetric position of sliding component 4 at low speed.For jut 11a and jut 11b ball screw 5 axially on the relative position relation aftermentioned.
At this, low speed is different with jut 10a, the 10b shape of sliding component 3 with high speed with jut 11a, the 11b of sliding component 4.Particularly, shown in Fig. 3 (a) and (b), on axial vertical cross section with respect to ball screw 5, with the height of the inner peripheral surface of sliding component 4 height greater than jut 10a, 10b, and the width of jut 11a, 11b is less than the width of jut 10a, 10b with respect to low speed for jut 11a, 11b.
As shown in Figure 1, ball screw 5 extends abreast with the groove 21,22 of door guide strip 20.
At this, as Fig. 4 and shown in Figure 8, be provided with at the outer peripheral face of ball screw 52 spiral helicine high speeds constituting by thread groove with slot part 6 and low speed with slot part 7.As shown in Figure 6, identical with respect to the screw winding direction of ball screw 5 with slot part 7 with slot part 6 and low speed at a high speed, as shown in Figure 5, the helical pitch A with slot part 6 is the 2 times sizes of low speed with the pitch B of the spiral of slot part 7 at a high speed.
At this,, different each other with slot part 6 and low speed at a high speed with the cross sectional shape of slot part 7 as Figure 6 and Figure 7.Specifically, at a high speed with the cross sectional shape of slot part 6 with at a high speed with the jut 10a of sliding component 3, the form fit of 10b, low speed is with the cross sectional shape and the low speed jut 11a of sliding component 4, the form fit of 11b of slot part 7.
At a high speed constitute low speed and can't enter this with jut 11a, the 11b of sliding component 4 and use at a high speed in the slot part 6, and low speed constitutes high speed with the cross sectional shape of slot part 7 and can't enter in this low speed usefulness slot part 7 with jut 10a, the 10b of sliding component 3 with the cross sectional shape of slot part 6.That is, as shown in Figure 7, low speed uses the degree of depth of slot part 7 greater than the degree of depth of using slot part 6 at a high speed, and low speed is used the width of slot part 6 less than high speed with the width of slot part 7.Shown in Fig. 7 (c), with slot part 6 and the intersection point part 5a of low speed, can enter with jut 10a, the 10b of sliding component 3 and low speed jut 11a, 11b both sides at a high speed with sliding component 4 with slot part 7 at a high speed.
For jut 10a and jut 10b ball screw 5 axially on relative position relation, and the relative position relation of jut 11a and jut 11b describe.
As shown in Figure 5, be set at a high speed: when the high speed that is in ball screw 5 with a side's of sliding component 3 jut 10a is at a high speed used the intersection point part 5a of slot part 7 with slot part 6 and low speed with the jut 10a of sliding component 3 and the relative position relation of jut 10b, the opposing party's jut 10b at a high speed with slot part 6 and the intersection point part 5a of low speed with slot part 7, only enter at a high speed with the state in the slot part 6 but become.
Equally, low speed is set at the jut 11a of sliding component 4 and the relative position relation of jut 11b: the high speed that is in ball screw 5 with a side's of sliding component 4 jut 11a when low speed is with slot part 6 and low speed during with the intersection point part 5a of slot part 7, the opposing party's jut 11b at a high speed with slot part 6 and the intersection point part 5a of low speed with slot part 7, only enter low speed with the state in the slot part 7 but become.
Be provided with motor 8 near a side's of ball screw 5 end, this motor 8 is connected with an end of ball screw 5 by having coupler or planetary reductor 9.By motor 8 ball screw 5 is rotated with certain rotary speed.
Then, the effect to this example of formation like this describes.
At first, at a high speed with door 1 and low speed with door 2 be positioned at motor 8 near, become this at a high speed with door 1 and low speed 2 the most in opposite directions states.At this moment, be embedded on ball screw 5 with sliding component 3 at a high speed, this inserts the high speed of ball screw 5 with in the slot part 6 with jut 10a, the 10b of sliding component 3 at a high speed.Equally, low speed is embedded on ball screw 5 with sliding component 4, and this low speed inserts the low speed of ball screw 5 with in the slot part 7 with jut 11a, the 11b of sliding component 4.In addition, as shown in Figure 1, at a high speed with sliding component 3 and low speed with sliding component 4 on ball screw 5, be embedded ball screw 5 axially on low speed with sliding component 4 than at a high speed with sliding component 3 more close motor 8.
Under such state when motor 8 makes ball screw 5 rotation with certain rotary speed, be directed to slot part 6 along the high speed of ball screw 5 at a high speed with jut 10a, the 10b of sliding component 3, this at a high speed with sliding component 3 towards direction moving axially along ball screw 5 away from motor 8.Equally, low speed is directed to slot part 7 along the low speed of ball screw 5 with jut 11a, the 11b of sliding component 4, this low speed with sliding component 4 towards direction moving axially along ball screw 5 away from motor 8.At this moment, because are low speed 2 times of sizes at a high speed, so use sliding component 3 to use 2 times of speed of sliding component 4 on ball screw 5, to slide at a high speed with low speed with the pitch B of the spiral of slot part 7 with the pitch A of the spiral of slot part 6.
Like this, can make at a high speed with door 1 and low speed with 2 with different speed towards moving with the gas direction.
As mentioned above, the door open/close machine of this example is at each sliding component 3,4 inner peripheral surface is respectively equipped with the different each other jut 10a (10b) of shape, 11a (11b), and the outer peripheral face at ball screw 5 is provided with and sliding component 3, the spiral helicine slot part 6 that varies in size of the mutual pitch of 4 equal numbers (2), 7, each slot part 6 of this ball screw 5,7 become and each self-corresponding each jut 10a (10b), the shape of the form fit of 11a (11b), each jut 10a (10b), 11a (11b) enters each self-corresponding slot part 6, in 7, but can't enter other slot parts 7, in 6.Therefore, even a plurality of slot parts 6,7 are set on 1 ball screw 5, the jut 10a (10a) of each sliding component 3,4,11a (11b) also can only be directed in each self- corresponding slot part 6,7, can be embedded a plurality of sliding components 3,4 on 1 ball screw 5.Therefore, with the drive unit that friction speed moves, can make the radical of ball screw 5 only be 1 at the door 1,2 that is used for making a plurality of sliding door types in the same direction, the number of motor 8 can only be 1 also.Like this, can simplify the structure that is used for moving each drive unit of 1,2 (motor 8 and ball screw 5), reduce to be provided with the space, improve maintainability.
On each sliding component 3 (4), be respectively equipped with a plurality of jut 10a, 10b (11a, 11b), each jut 10a, 10b (11a on the sliding component 3 (4), 11b) position relation is set at: when a side jut 10a (11a) was in intersection point part 5a of a plurality of slot parts 6,7 on the outer peripheral face of ball screw 5, the opposing party's jut 10b (11b) was not in other intersection point part of a plurality of slot parts 6 (7).Therefore, when a side jut 10a (11a) arrives intersection point part 5a of a plurality of slot parts 6,7, the opposing party's jut 10b (11b) only enters in the corresponding slot part 6 (7), so sliding component 3 (4) is definite with the relation of slot part 6 (7) by the opposing party's jut 10b (11b) with respect to the sliding action of ball screw 5, can prevent that a side jut 10a (11a) from entering corresponding slot part 6 (7) slot part 7 (6) in addition.Therefore, with the number of jut on being located at sliding component 3 (4) is that 1 situation is compared, (11a 11b) enters in the corresponding slot part 6 (7), can make each sliding component 3,4 carry out sliding action with respect to ball screw 5 reliably to make each jut 10a, 10b more reliably.
The door open/close machine of this example is not limited to above-mentioned form, can carry out various changes.
For example, be located at door open/close machine the sliding door type the door number be not 2 yet, can be more than or equal to 3.In the explanation of this variation, put on prosign with Fig. 1 to the identical part of example shown in Figure 8, and omit detailed explanation.
At this, when the number of the door of door open/close machine was n, establishing the fastest door of translational speed was No. 1 door, and translational speed the 2nd fast door is No. 2 doors, and is same, and (l≤k≤n) fast door is the k door to translational speed k, and the slowest door of translational speed is the n door.
At first, the formation to the sliding component of the upper end that is installed in each respectively describes.
If being installed in the height of the jut on the inner peripheral surface of the sliding component that closes with No. 1 badge is h
1, the height of establishing the jut on the inner peripheral surface that is installed in the sliding component that closes with No. 2 badges is h
2, the height of establishing the jut on the inner peripheral surface that is installed in the sliding component that closes with the k badge is h
k, then the height of each jut is h
1＜h
2＜...＜h
k＜...＜h
n
If the width of the jut corresponding with No. 1 door is w
1, the width of the jut corresponding with No. 2 doors is w
2, the width of the jut corresponding with the k door is w
k, then the width of each jut is w
1＞w
2＞...＞w
k＞...＞w
n
Then the formation to ball screw describes.
If the size of the pitch of the spiral of the slot part of the ball screw corresponding with No. 1 door is l
1, the size of the pitch of the spiral of the slot part corresponding with No. 2 doors is l
2, the size of the pitch of the spiral of the slot part corresponding with the k door is l
k, then the size of the helical pitch of each slot part is l
1＞l
2＞...＞l
k＞...＞l
nAt this, the size of the pitch of each spiral preferably with the integral multiple of the size of the helical pitch of the slowest corresponding slot part of door of translational speed.
Each slot part becomes the shape of the form fit of each jut corresponding with difference.At this, the degree of depth of establishing the slot part of the ball screw corresponding with No. 1 door is h '
1, the degree of depth of the slot part of the ball screw corresponding with No. 2 doors is h '
2, the degree of depth of the slot part of the ball screw corresponding with the k door is h '
k, then the degree of depth of each slot part is h '
1＜h '
2＜...＜h '
k＜...＜h '
nIn addition, the width of establishing the slot part of the ball screw corresponding with No. 1 door is w '
1, the width of the slot part of the ball screw corresponding with No. 2 doors is w '
2, the width of the slot part of the ball screw corresponding with the k door is w '
k, then the width of each slot part is w '
1＞w '
2＞...＞w '
k＞...＞w '
n
When the number of the door in the door open/close machine is n, because each sliding component and each ball screw have above-mentioned formation, each jut can enter in the corresponding slot part, but can not enter in other slot parts, n sliding component can be slided on ball screw in the same direction with different speed respectively.
