Embodiment Construction

[0017] The present invention will be further described in detail below with reference to the drawings and embodiments.

[0018] See figure 1 , figure 2 , image 3 , Figure 4 As shown, a pull-on jaw clutch device for underwater use includes a tooth ring 1, a jaw 2, and a magnetic core 12. A threaded hole is provided on the jaw 2, and a large key piece 8 is fixed by a screw 3. On the inlay 2; the small key piece 10 is fixed to the end of the screw sleeve 11 through the pressing piece 5 with a screw 3; a roller 9 is installed in the gap between the large key piece 8 and the small key piece 10, so that the The sliding friction at the spline connection between the jaw 2 and the screw sleeve 11 is converted into rolling friction between the large key piece 8 and the small key piece 10, thereby ensuring that the jaw clutch device can achieve reliable clutching under high torque. In order to prevent the rollers from falling off from the gap, a baffle piece 4 is fixed on the outer surfa...

Abstract

The invention discloses an underwater suction type jaw clutch device, which comprises a ring gear, a jaw, screws, a baffle plate, a pressing slice, a small key slice, a pin roller, a big key slice, a swivel nut, a magnetic core, a watertight socket, an adjusting screw, a spring, a fixing shaft, a key and a rotating piece, wherein the big key slice is fixed on the jaw through the screws; the smallkey slice passes through the pressing slice and is fixed at the end of the swivel nut through the screws; the pin roller is arranged on a gap between the big key slice and the small key slice; the external surface of the small key slice fixes the baffle plate through the screws; the inside of the magnetic core is provided with the adjusting screw and the spring; the magnetic core is connected with the swivel nut through threads; an external power supply is led in through the watertight socket; the swivel nut is fixedly connected with the fixing shaft through the key; and the ring gear is connected with the rotating piece through the screws. When the device is powered on, the jaw overcomes the acting force of the spring under the action of the electromagnetic force of the magnetic core so as to be separated from the ring gear and achieve the clutching function. The device can be arranged in underwater equipment and meets the demands of reliable clutching and stopping under the condition of large torque.

Description

Technical field [0001] The invention relates to a clutch device, in particular to a suction-on type jaw clutch device used for underwater, belonging to the field of mechanical structures. Background technique [0002] As a mature product, the jaw clutch device is widely used in various industrial fields. Its main purpose is to be used in various mechanical systems that need to be frequently combined to provide a bridge between the drive device and the output. [0003] Ordinary jaw clutch device has its advantages in use, namely, small size, large transmission torque; no idling torque, no frictional heating, no wear, no adjustment, constant transmission ratio, no slip, high repeat accuracy, use Long life, quick release, wet and dry. [0004] However, as an underwater mechanical device, there will be the following shortcomings during use: 1) Due to the lack of pressure-resistant structure, it cannot be directly used on large-depth underwater structures; 2) Generally, it needs to be st...
