Problems solved by technology

The input end is directly connected to the prime mover through a rigid connection, and the output end is connected to the output shaft through a rigid connection. This transmission method will cause noise and vibration due to the coaxiality deviation between the output shaft of the prime mover and the transmission shaft, and reduce the transmission unit. life, or even destroy the operation of the unit; when the unit is started and the clutch is disengaged, it will cause a great impact on the load or prime mover
In addition, bearings are usually used between the inner and outer races of traditional clutches, or additional bearings are required. Not only is the structure complex, the maintainability is low, and the performance of the bearings under frequent start-stop conditions restricts this type of single-phase transmission. reliability and service life

Embodiment 1

[0018] In Embodiment 1, the coupling half 2 is connected to the prime mover input shaft 1, the outer race 5 is connected to the power output shaft, and the coupling half 4 is connected to the inner race 6 through a key. The prime mover output shaft 1 drives the half-coupling 2 to rotate, and the half-coupling 2 drives the half-coupling 4 and the inner race 6 to rotate through 4 to 8 sets of elastic element assemblies and 2 to 6 sets of compression springs, and through the intermediate piece 7 And the action of the outer race 5 transmits torque, and the errors caused by manufacturing and assembly are compensated by elastic elements and compression springs. When the unit starts and stops, the continuous rotation of the output shaft will not affect the prime mover.

Embodiment 2

[0019] In Embodiment 2, the coupling half 2 is connected to the prime mover input shaft 1, the inner race 6 is connected to the power output shaft, and the coupling half 4 is connected to the outer race 5 through a key. The prime mover input shaft 1 drives the half-coupling 2 to rotate, and the half-coupling 2 drives the half-coupling 4 and the outer race 5 to rotate through 4 to 8 sets of elastic element assemblies and 2 to 6 sets of compression springs, and passes through the middle piece 7 And the action of the inner race 6 transmits torque, and the errors caused by manufacturing and assembly are compensated by elastic elements and compression springs. When the unit starts and stops, the continuous rotation of the output shaft will not affect the prime mover.

[0020] The lubricating oil circuit of the two schemes is divided into two parts at the same time, one part lubricates the middle piece 7 through the circumferentially arranged oil holes of the lower half coupling 4, ...

Abstract

The invention relates to a one-way transmission device with a coupling, and belongs to a transmission device of a power device. The one-way transmission device comprises a coupling, a one-way clutch, elastic element components and compression springs, wherein the clutch comprises an inner race and an outer race; the coupling comprises two half couplings, and the elastic element components and the compression springs are uniformly distributed between the two half couplings; one of the half couplings is in rigid connection with a prime mover input shaft, and the half coupling is connected with the other half coupling through the elastic element components and the compression springs; the other half coupling is in rigid connection with the inner race or the outer race of the clutch through a key and transfers torsion through the action of a middleware and the corresponding outer race or the corresponding inner race, and the end part of the corresponding outer race or the corresponding inner race is connected with an output shaft. The one-way transmission device not only can realize one-way transmission, but also can effectively compensate axial displacement, radial displacement and angular displacement between driving shaft systems and reduce vibration and noise, and has simple structure, high reliability and good economical efficiency.

Description

technical field [0001] The invention belongs to the transmission device of the power device, and specifically relates to a one-way transmission device with a coupling, which is used for the transmission shaft system of the marine power device, and is also suitable for the one-way transmission device with high requirements on coaxiality and installation. Clutch transmission shafting. Background technique [0002] The radiated noise of the ship's power plant is an important source of hull noise, and research work on reducing the noise and vibration of the power system has been extensively carried out at home and abroad. For the marine power transmission device with high life and high reliability, not only is it required to be able to smoothly realize wedging and disengagement, but also the clutch is required to be able to compensate certain displacement deviation, absorb vibration and reduce noise. [0003] At present, there are mainly three structural forms of commonly used ...
