Abstract

PURPOSE:To absorb the swing, etc. of a side brush to surely transmit rotation, by coupling the output shaft of a motor with the rotary shaft of a side brush through a flexible joint having a spherical surface bearing and resilient members. CONSTITUTION:A flexible joint 32 having a downwardly extending resilient member 31 is attached around the output shaft 28 of a speed reduction gear, a spherical surface bearing 30 being attached to the front end of the output shaft 28 through a pivot 29. Onto the top end section of a brush rotating shaft 25 is secured a coupling disc 34 which is engaged in its center section with the above- mentioned spherical surface bearing 30 and has holes 33 into which the resilient members 31 of the flexible joint 32 are fitted, so that rotation from the output shaft 28 is transmitted to the brush rotating shaft 25 through the resilient members 31. With this arrangement, the resilient members 31 absorb the swing of the side brush 5, and the spherical surface bearing 30 may maintain the rotating center.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a side brush bearing device, and more particularly to a side brush bearing device commonly used in car wash machines.

In a car wash machine with a gate-shaped frame, the side brushes are attached along the side frames of the gate-shaped frame so that they can be rotated and driven to open and close. It is designed to be cleaned.

Bearings are usually used as bearings to support such side brushes, but if the side brushes start rotating with a slight inclination, eccentricity or shaking will occur, so the bearings will not allow rotation. This has the disadvantage that the transmission efficiency deteriorates. This problem is particularly likely to occur in car wash machines in which the length of the side brushes is increased in order to be applied to vehicles with high vehicle height, such as double-disconnected buses.

The present invention has been made based on the above-mentioned points, and an object of the present invention is to provide a side brush bearing device that can absorb vibrations of the side brush, etc. and can reliably transmit rotation. and a rotating shaft of the side brush are connected via a flexible joint having a spherical bearing and an elastic member.

Embodiments of the present invention will be described below with reference to FIGS. 1 to 6.

FIG. 1 shows an embodiment of a car wash machine to which the present invention is applied, in which a top brush 3 is provided along an upper frame 2 of a gate-shaped frame 1 so as to be rotatable and can be driven up and down. A pair of side plans 5.5 are provided along the frame 4 so as to be rotatable and open/closeable. The top brush 3 is movable by being placed on parallel rails 6 and 2 (not shown) mounted on the lower part of the side frame 4. As shown in Figure 3, there is a brush elevating shaft 7 disposed on the central axis, and a cylinder coaxially arranged on the outer circumferential side of the brush elevating shaft 7 and having a large number of brushes 8 implanted on its outer circumferential surface. Each shaft 7.9 has a bearing 10,
10, so that they can rotate independently from each other.

A lifting motor 11 is mounted on one end side of the brush lifting shaft 7.
A reduction coupling L/l, 12 to which is connected is attached, and a rotation motor 13 is disposed on the other end side. It is connected to the fixed joint member 4 via a speed reduction device 15.

Further, the guide rail 1 has a U-shaped cross section and has a rack gear 16 attached to one of the inner surfaces along the longitudinal direction.
7 are provided to face both sides of the portal frame 10, and pinion gears 18, 18 attached to both ends of the brush elevating shaft 7 are connected to the power idle rails 17, 1.
The trap is made so as to mesh with the rack gears 16, 16 of No.7. Furthermore, at the upper and lower positions of each of the pinion gears 18, 18, there are soft rollers 19a + 19a + 19b that contact the inner surfaces of the guide rails 17, 17.
*19b is rotatably arranged, and this guide roller 19
The shafts of a r19a, 19b, and 19b are attached to the side surfaces of each of the reduction gears [12, +5]. One of the guide rails 19a *19a has an H-shaped cross section in the diametrical direction so as to straddle the rack ears 16, and prevents the brush lifting shaft 7 from shifting in the lateral direction.
b and the pinion gear 18 are prevented from coming apart.

The top brush 3 is constructed by rotating the brush rotation shaft 92 by driving the rotation motor 13, rotating the brush lifting shaft 7 by driving the 1 lifting motor 11, and by meshing the pinion gear 18 and the rack gear 16. is raised and lowered along guide trays #17' and 17. By arranging the rotation motor L3 and the lifting motor 11 above the rotation axis of the top brush 3 in this way, it is possible to significantly reduce the installation space while maintaining the right and left weight balance.

4 to 6 show the structure of the side brushes 5. Since the side sills 75 are provided symmetrically, one side brush 5 will be explained.

A side brush support member rib extending in the vertical direction along the side frame 4 is rotatably provided, and first arms 21 p 21 are integrally provided to extend horizontally from the upper and lower parts of the brush support member. There is. The first arms 21, 21 have a shape in which the middle portions are bent in a horizontal plane, and second arms η, 22 are rotatably attached to the ends of the first arms 21, 21, respectively. installed. A bearing is fixed to the end of the second arm 4 on the lower side, and a large number of graphs 2 are formed on the outer peripheral surface by this bearing n.
4 supports the lower end of the brush rotating shaft part implanted therein. Furthermore, a reduction gear device n to which the rotation motor A is connected is connected to the upper end of the brush rotation motor.

FIG. 6 shows the bearing structure of the reduction gear 27 and the shaft for rotating the brush.A spherical bearing (bearing) is attached to the tip of the output shaft row of each reduction gear via via holes 4. A flexible joint 32 having an elastic member 31 made of rubber or the like extending downward is attached around the output shaft path. A coupling disk having a hole 33 into which the elastic member 31 of the flexible joint 32 is fitted is fixed to the upper end of the brush rotation shaft and engages with the spherical bearing blade at the center thereof. The rotation from the output shaft is transmitted to the brush rotation shaft 5 via the elastic member 31. Therefore, the vibration of the side plush 5 can be absorbed by the elastic members 31, 31, and the center of rotation can be maintained between the spherical bearings.

Further, an opening/closing drive motor is connected to the upper part of the reduction gear 27, and a reduction gear is fixed to the end of the second arm 4 on the upper side, and the output from the device 36 is fixed. The rotation centers of the yMrA drive shaft 37 and the output shaft are made to coincide with each other.

A guide roller 38 is attached to the end of the opening/closing drive shaft 37 so that it can rotate freely, and a pinion gear 39 is fixed to the end of the opening/closing drive shaft 37.
The rack gear 41 is fixed longitudinally to the inner surface of a guide rail 40 provided along the upper frame 2, and the guide rollers are in contact with the inner surface of the guide rail 40. .

The side brush 5 is rotated by the rotation motor 26, and opens and closes along the guide rail 40 by the rotation of the opening/closing ground motion motor. In addition, each arm 21
．． 22 supports the side brush 5 in the vertical direction.

Therefore, by providing the motors 27 and 36 coaxially, the mounting space can be reduced.

As described above, the side brush bearing device according to the present invention has a spherical bearing attached to the tip of the output shaft, a flexible joint having an elastic member around the output shaft, and a coupling fixed to the upper end of the rotating shaft. Since the elastic member is inserted into the hole of the disk and the spherical bearing is engaged with the center of the disk, the spherical bearing allows the side brush to tilt, thereby preventing the side brush from swinging. It can be absorbed by the elastic member, and therefore, the rotation of the output shaft can be effectively transmitted to the rotation shaft.
