Abstract
The utility model relates to a locking ring of a photoelectric encoder and belongs to the parts of a photoelectric instrument. A locking screw is in threaded connection with two sides of the opening of a ring body; the position which is away from the opening of the ring body by 120 degrees in clockwise direction is provided with a round hole with a through groove; and the position which is away from the opening of the ring body by 120 degrees in anticlockwise direction is provided with the round hole with the through groove. The locking ring has the advantages of being novel in structure and even in locking, adopting three-point locking, and meeting the requirements of mechanics principle and radial locking; the force evenly acts on a hollow shaft and does not lead the hollow shaft to become deformed; the linking is firm and reliable, and the assembly and disassembly are convenient; the rotating shaft of the photoelectric encoder is coaxial with the shafts of a motor and a traction machine, which does not affect the using precision of the photoelectric encoder due to the linking, and does not generate relative angular displacement and swing with the installation shaft.
Description
Technical field
The utility model belongs to the parts of photoelectric instrument.
Background technology
Along with science and technology development, photoelectric encoder is widely used in each field of national economy.The method that is connected and fixed of photoelectric encoder axle and motor or machine shaft directly has influence on the application of photoelectric encoder.Key connecting can produce eccentric and radially string is moving, and the rotation center and the fixed orifice center of not satisfying photoelectric encoder are coaxial.Especially it is too big to produce error at high sign indicating number position photoelectric encoder, can't use.The another kind of ring that adopts connects, and as Fig. 1, both sides are afterburning fixing.Though can not produce radially fine motion, can produce and radially wobble, still can produce error.And 2 to be fixed on the friction force that produces under the fixing coupling mechanism force little, can cause looseningly, strengthens coupling mechanism force and can make axle produce distortion, do not meet mechanics principle and radially lock requirement.
Summary of the invention
The utility model provides a kind of photoelectric encoder retaining ring, when adopting ring to connect to solve, fixes for 2 and can cause loosening problem.The technical scheme that the utility model is taked is: lock-screw is threaded with the opening part both sides of ring body, at the clockwise 120 ° of circular holes of locating to have a band groove of the opening part of distance ring body, at the counterclockwise 120 ° of circular holes of locating to have a band groove of the opening part of distance ring body.
When screwing lock-screw, be subjected to internal force as 3, stressedly evenly can not cause distortion to axle, because garden arc and garden contact, contact area is big, has increased friction, locks solid and reliable.
The utility model advantage is a novel structure, evenly locking.Adopt 3 lockings, meet mechanics principle and radially lock requirement, the power stepless action can not make tubular shaft produce distortion to tubular shaft.Connect solid and reliablely, charge and discharge operations is convenient.The turning axle that makes photoelectric encoder and motor, machine shaft are coaxial, can not influence the photoelectric encoder service precision because of connecting, and can not produce relative angular displacement and swing with installation shaft.

Embodiment
Lock-screw 2 is threaded with the opening part both sides of ring body 1, at opening part 3 clockwise 120 ° of circular holes 5 of locating to have a band groove of distance ring body 1, at the counterclockwise 120 ° of circular holes 4 of locating to have a band groove of the opening part of distance ring body 1.
Claims (1)
1, a kind of photoelectric encoder retaining ring, lock-screw is threaded with the opening part both sides of ring body, it is characterized in that: at the clockwise 120 ° of circular holes of locating to have a band groove of the opening part of distance ring body, at the counterclockwise 120 ° of circular holes of locating to have a band groove of the opening part of distance ring body.
