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 half coupling 2 is connected with the prime mover input shaft 1, the outer race 5 is connected with the power output shaft, and the half coupling 4 and the inner race 6 are connected by keys. The prime mover output shaft 1 drives the half-coupling 2 to rotate. The half-coupling 2 drives the half-coupling 4 and the inner race 6 to rotate through 4-8 sets of elastic element components and 2-6 sets of compression springs, through the middle piece 7 The torque is transmitted by the action of the outer race 5, 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.

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 passes through the circumferentially arranged oil holes of the lower half coupling 4 to lubricate the intermediate piece 7, an...

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 thecompression 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 akey 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 a transmission device of a power device, and specifically relates to a one-way transmission device with a coupling, which is used for the transmission shaft system of a marine power device, and is also suitable for a one-way transmission that requires high coaxiality and installation and use. Clutch drive shaft system. Background technique [0002] The radiated noise of ship power plant is an important source of hull noise, and research work on reducing noise and vibration of power system is widely carried out at home and abroad. For long-life, high-reliability marine power transmission devices, it is not only required to smoothly achieve wedging and disengagement, but also requires the clutch to compensate for a certain displacement deviation, absorb vibration and reduce noise. [0003] At present, commonly used clutches mainly have three structural forms: friction plate clutch, wedge one-way clutch, roller one-way clutch. The inpu...
