PROBLEM TO BE SOLVED: To provide a jig capable of skillfully positioning magnet material in a yoke having a small diameter. SOLUTION: A positioning jig 20 of magnet material 5 is equipped with a guide trench 22, which obliquely guides magnetic material 5 on which adhesive agent is spread from a yoke 2 center side towards an inner peripheral surface 2a, and a guide segment 23 which guides both sides 5c of the magnetic material 5 so as to define a fixing angle of the magnet material 5 which has approached the inner peripheral surface 2a. As a result, the magnetic material is sufficiently isolated from the inner peripheral surface of the yoke during the time from working start until positioning, and there is no concern for the adhesive agent coming into contact with the inner peripheral surface and peel. Hence the efficiency of fixing work of the magnetic material can be improved.

PROBLEM TO BE SOLVED: To provide a toothed belt transmission device for use in business equipment or the like such as a printer and copier, in which unevenness in the toothed belt 8 speed is reduced to possible minimum and the printing accuracy and image quality of the business equipment are enhanced. SOLUTION: The tooth part 13 of the belt 10 is composed of a pair of dedendum parts 14, a pair of tooth flanks 15 consisting of convex circular arc surfaces, and a tooth tip 16 continuing the two tooth flanks 15 and consisting of circular arc surface parts 17 continuing to the circular arc surfaces of the tooth flanks 15 and one plane 18 whereby the two circular arc surface parts 17 are connected together, while each pulley tooth groove part 3 of a toothed pulley 1/2 is composed of a pair of tooth crest circular arc parts 4, a pair of tooth groove side faces 5 consisting of concave circular arc surfaces, and a tooth groove bottom part 6 formed so that the two tooth groove side faces 5 are connected together, and in the transmitting condition in which the belt 10 is wound on pulleys 1 and 2, the belt land part 12 and pulley periphery 9 are held out of contact. When the belt tooth 13 bites into the pulley tooth groove part 3, rotation is generated round the point O' on the belt pitch line PL mating with the area around the back dedendum of the pulley tooth groove part 3 adjoining to the front in belt running direction of the applicable pulley tooth groove part 3.

Toothed belt transmission device and business equipment

PURPOSE:To provide the clutch of a starter by which wear of a bearing surface in the vicinity of a pinion gear is reduced and favorble torque transmission from a pinion gear to a ring gear is attained. CONSTITUTION:In the disengaged condition between a pinion gear 45 and a ring gear on the engine side, the clearance C1 between the rear part of a pinion inner 42 covering the helical groove part 23 of an output shaft 20 namely the inner circumferential face of a clutch inner 47 and the helical groove part 23, is set narrower than the clearance C2 between the bearing surface F of the front part of the pinion inner 42 and the output shaft 20. Consequently, at retreating the clutch, vibration of the output shaft 20 is transmitted to the clutch 4 through the fitted part between the helical groove part 23 and the clutch inner 47, but not transmitted through the fitted part between the bearing surface F of the front part of the pinion inner 42 and the output shaft 20, so as to reduce wear of a pinion metal 46.

Clutch of starter

PURPOSE:To facilitate the fitting of a magnet by supporting cut and rise sections butted to respective confronted surfaces in the peripheral and axial directions of the magnet, on the inner peripheral surface of a sleeve. CONSTITUTION:The yoke 1 of a magnet type motor is formed in the shape of a cylinder having a bottom with a steel plate, and on the bottom section of the yoke 1, a bearing section, la for supporting the rotary shaft 2a of a rotor (armature) 2 is formed. Then, a sleeve 3 set on the inner peripheral surface of the yoke 1 is a magnetic body, and the outer diameter of the sleeve is made larger than the inner diameter of the yoke 1. Two magnets 4 arranged on the inner peripheral section of the sleeve 3 are formed in circular shapes, and at both end sections on the one side surface in the peripheral direction, notched sections 5, 6 are respectively formed. On the sleeve 3, cut and rise sections 7 are formed, and come in contact with one side surface in the peripheral direction of the magnets 4, and in the same manner, cut and rise sections 8, 9 are formed, and are respectively butted to said notched sections 5, 6. Then, the cut and rise sections 7-9 are butted to each surface in the peripheral and axial directions of the magnets 4, and the movement of the magnets 4 in the directions can be regulated.

Magnet type motor

PURPOSE:To absorb impact force at the time of driving a ring gear by employing both a first elastic body furnished with a specified frictional coefficient and a second elastic body furnished with a specified frictional coefficient greater than that of the first elastic body in the axial direction between a tube and a pinion. CONSTITUTION:Torque imparted to a shaft 2 is transmitted to a tube 5, and is then transmitted to a cover 10 and a pinion 3 via a second elastic body 7 furnished with a great frictional coefficient functioning between the tube 5 and the cover 10. The pinion 3 is pushed by a first elastic body 6 as the tube 5 is advanced on the shaft 2 by means of the action of a helical line 2a, so that the pinion is meshed with a ring gear 4. In this case, advancing impact force caused by the collision of the pinion 3 against the ring gear 4 is absorbed by the first elastic body 6, and the second elastic body 7 is subjected to low load as the first elastic body 6 is deformed, so that frictional force between the tube 5 and the cover 10 thereby becomes low. As a result, impact force caused when the pinion 3 is shifted to drive the ring gear 4 is thereby absorbed.

Inertial plunging type starter

PURPOSE:To hinder the axial displacement of a permanent magnet by axially holding the permanent magnet between the projection provided on the yoke opening side and a two-stage drawn part provided on the deeply inside the yoke. CONSTITUTION:A permanent magnet 2 is built in place in a yoke 1 while the notch 21 of the permanent magnet 2 is engaged with the projection 11 provided on the yoke 1 opening side and the inmost side end face 22 of the permanent magnet 2 is brought into contact with the inside of the part 13 with difference in level of a two-stage drawn part 13 provided in the yoke 1. Then, a protective cover 3 is inserted into the permanent magnet 2 while the projection 11 of the yoke 1 and the notch 37 of the protective cover are fitted to each other. Thereafter, the protective cover 3 is subjected to building of the inside diameter for the purpose of causing overhang parts 35, 36 to bulge out so that the protective cover 3 is fixed and building of the protective cover in the yoke is completed. When the permanent magnet is held between the projection of the yoke and the two-stage drawn part, it is possible to hinder the axial displacement by an external mechanical force. Therefore, it is possible to surely fix the permanent magnet and the protective cover without making an apparatus larger.

Stator of magneto electrical rotating machine

PURPOSE:To eliminate pump operating sound offensive to the ear during operational confirmation of an antilock brake system. CONSTITUTION:In a motor 2 for a starter 1, a movable contact 18a within a magnet switch 7 touches a fixed contact 19a, 20a so that a starter circuit B is closed, and thus an armature 12 is rotated. A driving portion 27 of a hydraulic pump of ABS is fixed to a rotating shaft 12a of the armature 12, so that the hydraulic pump is driven in rotation by the motor 2. The motor 2, on the other hand, is connected to a motor circuit C connected to a battery, through other motor terminal 19 of the magnet switch 7. In the motor circuit C, a switch 28 only for a motor is disposed, independent of the magnet switch 7, fur supplying power to the motor 2. The motor switch 28 becomes ON/OFF under the control of a control device 25 of ABS.
