Description

Clutch for small high-speed low-load transmission Technical Field The utility model relates to the technical field of clutches, in particular to a clutch for small high-speed low-load transmission. Background In the field of small-sized high-speed low-load transmission, such as precise instruments, small-sized automatic equipment and the like, the clutch is used as a key component for realizing power transmission and separation, and the performance of the clutch directly influences the stability and the service life of the whole transmission system. When the existing clutch is coupled with a shaft for transmission, force transmission is concentrated on a contact surface due to rigid contact between parts, and the stress concentration phenomenon is obvious because the contact moment is extremely small in stress area. Meanwhile, the traditional embedded clutch is in rigid connection at the moment of contact in the clutch process, so that the impact force is larger. In the high-speed operation process, vibration and impact generated by the system can directly act on each part of the clutch, after long-term use, part abrasion, deformation and even breakage are easy to occur, the whole service life of the clutch is seriously shortened, the maintenance cost and the shutdown time of equipment are increased, and the clutch is of an integrated or complex integrated structure, when a certain part breaks down and needs to be maintained or replaced, the whole clutch is often required to be disassembled, and even professional tools and technicians are required to operate. The present utility model therefore proposes a clutch for small high-speed low-load transmission. Disclosure of utility model The utility model aims at solving the problems that in the prior art, the existing clutch is in rigid contact when in coupling transmission with a shaft, force transmission is concentrated on a contact surface, and the contact is in rigid connection at the moment, so that impact force is large, vibration and impact generated by a system can directly act on each part of the clutch in the high-speed operation process, after long-term use, part abrasion, deformation and even fracture are easy to occur, the whole service life of the clutch is seriously shortened, the maintenance cost and the shutdown time of equipment are increased, in addition, most of the clutch is of an integrated or complex integrated structure, when a certain part fails and needs to be maintained or replaced, the whole clutch is often required to be disassembled, even professional tools and technicians are required to operate, the maintenance process is complicated, the time is long, and the maintenance difficulty and the cost are increased. The technical scheme includes that the clutch for small-sized high-speed low-load transmission comprises a ball retainer, a transmission shaft, a connecting assembly and a connecting assembly, wherein a first ball groove is formed in the inner annular surface of the ball retainer, balls are arranged in the first ball groove, the transmission shaft is movably sleeved with the ball retainer, a second ball groove which is clamped with the balls is formed in the outer wall of the transmission shaft, and the connecting assembly is clamped and arranged on the outer wall of the ball retainer. Optionally, the coupling assembling includes outer connector and back structure support body, the recess has been seted up respectively to the interior ring face of outer connector and back structure support body, the inside joint of recess is provided with the boss, the outer wall fixed connection of boss and transmission shaft, connect through rubber gasket between outer connector and the back structure support body, still be provided with the rubber piece between outer connector and the back structure support body. Optionally, the front end face of the outer connector is provided with a plurality of through holes. Optionally, a first clamping groove for positioning the rubber gasket is formed in one side, facing the rubber gasket, of the outer connector, and a part of the rubber gasket is embedded into the first clamping groove. Optionally, a second clamping groove matched with the rubber gasket is formed in one side, facing the rubber gasket, of the rear structural support body, and the other side of the rubber gasket is embedded into the second clamping groove. Optionally, the overall dimension of rubber gasket and the terminal surface size looks adaptation of outer connector and the butt joint of back structural support body, and set up the logical groove that supplies the rubber piece to pass on the rubber gasket. In summary, the present application includes at least one of the following beneficial technical effects: According to the utility model, through the ball matching structure between the ball retainer and the transmission shaft, partial acting force when the clutch is coupled with the shaft is converted into relative rolling of
