Description

Technical Field

[0001] The invention belongs to the technical field of assembly equipment, and in particular relates to an interval blocking transmission device. Background Art

[0002] Transmission devices are used in many fields. With the development of science and technology, various transmission devices have been developed in today's society. When a partition device is set between two rotating shafts, it is usually to achieve the following purposes: to isolate vibration, reduce noise, prevent medium leakage, or because there is a need for relative motion between the two shafts or other special needs. The existing solution usually uses magnetic drive to achieve contactless transmission between two rotating shafts.

[0003] Application No. CN202311519591.9 discloses a magnetic marine centrifugal high-pressure pump, which includes a pressure shell and a fluid-conducting pressure shell to form a pump body. A motor is provided on the top of the pump body, and a magnetic coupling is provided between the output shaft of the motor and the pump shaft. The magnetic coupling is connected to the pump shaft in the pump body by transmission. The outer magnetic ring and the inner magnetic ring of the magnetic coupling are separated by an isolation cover. A gap is reserved between the outer side of the linkage shaft and the middle part of the pump body, and a liquid guide hole is provided on one side of the ring gland. By setting a magnetic coupling between the motor and the pump shaft, a contactless sealed transmission is achieved, avoiding the problem of leakage of the transmission part due to wear. However, in some cases where there is no rotation error between the two rotating shafts and the transmission force is large, it is not appropriate to use magnetic transmission. Therefore, it is necessary to study a transmission method without any rotation error when blocked. Summary of the invention

[0004] The purpose of the present invention is to address the problem that in the existing contactless magnetic transmission method, under the condition of large torque, rotational errors between the two transmission shafts will occur, which cannot be applied in some situations where no rotational errors are allowed. An interval blocking transmission device is proposed, in which the main rotating disk, the interval blocking device and the auxiliary rotating disk are successively sleeved on the central axis, the transmission buckle is installed on the main rotating disk, and the main rotating disk drives the auxiliary rotating disk to rotate through the transmission buckle. The interval blocking device compresses the transmission buckle downward during the rotation process, thereby passing through the connection between the main rotating disk and the auxiliary rotating disk. At the same time, by setting a compressible transmission buckle connection method, power transmission between the two rotations is realized in the case of interval blocking.

[0005] In order to solve the above technical problems, the present invention provides an interval-blocking transmission device, including: a central axis, a main rotating disk, an interval-blocking device, a transmission buckle, a secondary rotating disk and a compression spring; the main rotating disk, the interval-blocking device and the secondary rotating disk are sequentially sleeved on the central axis from the bottom of the central axis, the bottom surface of the second rotating ring of the secondary rotating disk contacts the upper surface of the interval-blocking device, the transmission buckle groove of the main rotating disk is inserted and connected with the transmission buckle limiting boss of the transmission buckle, the transmission buckle main rod body of the transmission buckle is inserted and connected with the transmission hole of the secondary rotating disk, a compression spring is arranged in the spring mounting hole of the main rotating disk, the main rotating disk drives the secondary rotating disk to rotate through the transmission buckle, and the transmission buckle is compressed downward during the rotation of the interval-blocking device, thereby passing through the connection between the main rotating disk and the secondary rotating disk.

[0007] Preferably, the spacing blocking device comprises a blocking device sleeve and a blocking cross bar fixedly connected around a circular surface on one side of the blocking device sleeve.

[0008] Preferably, the blocking cross bars are arranged at equal distances from each other and the setting side of the blocking cross bars is close to the auxiliary rotating disk.

[0009] Preferably, the middle part of the transmission buckle is a transmission buckle main body platform, a transmission buckle limiting boss is arranged at the lower end of the transmission buckle main body platform, a transmission buckle compression slope is arranged on the outer side of the upper end of the transmission buckle main body platform, and a transmission buckle main rod body is arranged on the inner side.

[0010] Preferably, a plurality of equally spaced transmission holes are arranged on the edge of the auxiliary rotating disk body of the auxiliary rotating disk, and second rotating circular rings are arranged opposite to each other on two side circular surfaces of the auxiliary rotating disk body.

[0011] Preferably, the central shaft is in cylindrical form, providing a fixation for the rotation axis of the transmission device.

[0012] Preferably, the plurality of transmission buckle compression slopes are arranged in a counterclockwise direction, the rotation direction of the spacing blocking device is opposite to the arrangement direction of the transmission buckle compression slopes, and the setting length of the blocking cross bar is greater than the distance from the transmission buckle compression slope to the central axis.

[0013] Beneficial effects of the present invention:

[0014] 1. This scheme is to sequentially sleeve the main rotating disk, the interval blocking device and the auxiliary rotating disk on the central axis, install the transmission buckle on the main rotating disk, and the main rotating disk drives the auxiliary rotating disk to rotate through the transmission buckle. The interval blocking device compresses the transmission buckle downward during the rotation process, thereby passing through the connection between the main rotating disk and the auxiliary rotating disk, thereby ensuring the normal connection between the main rotating disk and the auxiliary rotating disk.

[0015] 2. This solution solves the problem that it is usually difficult to achieve power transmission between two rotating planes when there is another form of rotation obstruction between the two rotating planes by setting a transmission buckle. It realizes power transmission between the two rotations in the case of interval obstruction and ensures that the rotation error between the two rotating axes is small.
