全装置に関する。[Detailed Description of the Invention] The present invention provides a pair of power transmission rotors that are loosely fitted onto a shaft, and urges one of the pair of power transmission rotors toward the other power transmission rotor. A spring is provided, and a clutch piece is slidably provided on the shaft and can be freely engaged with and disengaged from one of the pair of power transmission rotors to intermittent the power; The present invention relates to a transmission safety device, which is provided with a safety clutch portion between the two rotating bodies, which resists the biasing force of the spring and separates the two rotating bodies from each other to cut off the transmission when the transmission torque exceeds a set value.

業性の悪い不利があり、改善の余地があつた。 Conventionally, in such a safety device, a pair of rotating bodies, a spring, and a receiving member for the spring are each separately attached to a support shaft. When attempting to assemble it, each part must be assembled separately within the narrow space inside the case, and in particular, it takes time to assemble the spring to the desired elastic deformation state, making the assembly process time-consuming. There was a disadvantage that assembly workability was poor, such as the cumbersome work required, and there was room for improvement.

の付勢力が狂うことがないようにする点にある。 The present invention was devised in view of the above-mentioned circumstances, and its purpose is to improve assembly workability and make the device more compact for that purpose through simple modification, and to provide a transmission safety device. The purpose is to prevent the biasing force of the spring from being disturbed due to a hand touching the spring receiving member when assembling the surrounding transmission gear.

通りである。 The characteristic configuration of the transmission safety device according to the present invention is that a cylindrical portion into which the one transmission rotation body is slidably fitted is connected to the other transmission rotation body of the two rotation bodies; The spring is positioned between the spring receiving member externally fitted onto the cylindrical portion and the sliding rotating body, and the contact portion of the spring receiving member with respect to the spring is The threaded portion that is threaded into the cylindrical portion is located in an axial direction on a side opposite to the side where the sliding rotating body is located;
Furthermore, the clutch piece is constructed from a cylindrical cover body that covers the outer periphery of the spring receiving member and the spring, and its effects are as follows.

安全装置を得るに至つた。 That is, since the safety device can be made into a unit shape by assembling the other rotating body, spring, and spring receiving member to the cylindrical part connected to one of the two rotating bodies, the safety device can be made into a unit shape in advance. By adopting the procedure of assembling it into the desired transmission mechanism after assembling it into the transmission case, the assembly work can be carried out efficiently even if it is assembled in a narrow space inside the transmission case. Furthermore, when assembling the safety device into a unit, the spring can be manipulated into a desired elastic deformation state by simply rotating and moving the spring receiving member, so the spring can be adjusted to the desired elastic deformation state. The safety device can be efficiently assembled as a unit without the hassle of assembling it in a deformed state, and as a whole, it is a power transmission safety device with excellent assembly workability and great practical advantages. I finally got the device.

に比してユニツト化した安全装置のコンパクト化
をはかれる利点がある。 Furthermore, the contact portion of the spring receiving member with respect to the spring is placed on the side opposite to the side where the sliding side rotary body is located in the axial direction from the threaded portion of the spring receiving member that is screwed into the cylindrical portion. For example, the spring receiving member may have a circular plate in which the abutting portion for the spring is located at the same position in the axial direction as the threaded portion for the cylindrical portion of the spring receiving member. This has the advantage that the unitized safety device can be made more compact than the case where the safety device is constructed from a shaped spring receiving member.

ンパクトに構成し得る利点がある。 In other words, when assembling the safety device into a unit, the spring is fitted onto the cylindrical part in a free state, the spring receiving member is screwed onto the cylindrical part, and the spring receiving member is attached from there. The torque will be set with the tightening combine,
If the structure simply uses a disc-shaped spring receiving member, it would be necessary to increase the length of the cylindrical part in the axial direction in order to allow the spring to fit freely. A structure using a spring receiving member in which the abutting part of the spring receiving member for the spring is located on the side opposite to the sliding rotating body in the axial direction from the threaded part for the cylindrical part. If there is, the spring can be fitted freely without increasing the axial length of the cylindrical part, and even if the spring receiving member is tightened to set the torque, the spring receiving member will not fit Since the cylindrical part does not protrude behind the member, there is an advantage that the unit-shaped safety device can be constructed compactly.

言うようなことがない。 Furthermore, since the clutch piece is composed of a spring receiving member and a cylindrical cover body that covers the outer circumference of the spring, for example, the clutch piece is composed of a disk portion externally fitted around the shaft and a disk portion of the disk portion. On the outer periphery
around the transmission safety device, such as when the clutch pawl is arranged at appropriate intervals in the circumferential direction and consists of a portion along the axial direction and a clutch pawl provided at the tip of the portion along the axial direction. When assembling a transmission gear, the spring receiving member may be touched by a hand or a tool through the gap between the members along the axis of the clutch piece, and the spring biasing force must be readjusted. Furthermore, there is no possibility that the transmission oil will be stirred to a large extent by members running along the axis of the clutch piece.

A spring 19a is provided for biasing one of the transmission rotors 17 toward the other transmission rotation body 15 side, and the shaft 8 is further provided with a spring 19a that biases one of the transmission rotation bodies 17 toward the other transmission rotation body 15 side.
A clutch piece 16 that can be freely engaged with and disengaged from one of the transmission rotary bodies 17 is slidably provided to interrupt the power. The transmission safety device is provided with a safety clutch portion C3 that resists the biasing force of the spring 19a and separates the two rotating bodies 15 and 17 from each other to cut off the transmission when A cylindrical portion 15A into which the one transmission rotation body 17 is slidably fitted is connected to the other transmission rotation body 15 of the transmission rotation bodies 15 and 17,
The spring 19a is positioned between the spring receiving member 18 externally fitted onto the cylindrical portion 15A and the sliding rotary body 17, and a contact portion 18a of the spring receiving member 18 with respect to the spring 19a is provided. , the spring receiving member 18
In the axial direction, the sliding side rotating body 17
It is located offset to the side opposite to where it is located,
Furthermore, the transmission safety device is characterized in that the clutch piece 16 is constituted by a cylindrical cover body that covers the outer periphery of the spring receiving member 18 and the spring 19a.
