Description

Technical Field

[0001] The utility model relates to the technical field of motor protection, and specifically relates to a ratchet clutch for double-sided motor protection. Background Art

[0002] A dual-side motor typically consists of two motors, one on each side of a device or machine, working together to achieve a specific function. Each motor has its own independent stator and rotor. When energized, the stator generates a magnetic field that interacts with the rotor's magnetic field, causing the rotor to rotate and generate power. The two motors can operate synchronously or be independently controlled and adjusted as needed. This structural design allows for greater spatial flexibility in dual-side motor placement, allowing for precise placement based on specific application requirements. For example, in equipment requiring high torque output, the two motors can be arranged symmetrically to balance torque and improve stability.

[0003] In the prior art, after the double-sided motors stop, the equipment rotor will reverse due to internal material or structural problems, and the rotation will be transmitted to the motor and cause damage to the electrodes. The present invention solves the above problem. Utility Model Content

[0004] In order to solve the technical problem in the prior art that after the double-sided motors stop, the equipment rotor will reverse due to internal material or structural problems, and the transmission to the motor will cause damage to the motor, the utility model provides a ratchet clutch for protecting the double-sided motors.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a ratchet clutch for double-sided motor protection, comprising: a transmission box, a shaft 1 is rotatably connected in the transmission box, the shaft 1 is connected to the power of the motor on one side, a shaft sleeve is loosely fitted on the shaft 1, the transmission mechanism can transmit the power of the motor on the other side to the shaft sleeve, a ratchet 1 is connected to the shaft sleeve, the ratchet 1 is loosely fitted with the shaft 1, the ratchet 1 and the ratchet 2 are engaged through the ratchet teeth, the ratchet 1 and the ratchet 2 can only transmit in one direction, the ratchet 2 is connected to the shaft 1, a spring is sleeved on the shaft 1, the spring is located between the inner wall of the transmission box and the shaft sleeve, and the spring is in a compressed state.

[0006] Preferably, the transmission mechanism includes shaft 2, which is connected to the motor power and rotatably connected to the transmission box. The axes of shaft 2 and shaft 1 are located in different vertical planes. Both shaft 2 and shaft 1 are connected to sprockets, and the two sprockets are connected by a chain, with a margin left for the chain length.

[0007] Preferably, two sprockets are connected to shaft two and shaft one respectively, and the four sprockets and two chains form two sets of chain drives.

[0008] Compared with the prior art, the beneficial effects of the present invention are:

[0009] When the rotor of the equipment rotates in reverse, the two ratchets stagger with each other along the contact slope, and the rotor reverse power will not be transmitted to the motor. When the motor rotates in the forward direction, the two ratchets transmit power through the straight contact surface, driving the rotor to rotate in the forward direction, thereby protecting the motor.

[0010] There is a margin in the chain length between the two sprockets so that the transmission will not be disconnected whether the sleeve is stationary or sliding. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] The rotational connection described in this device refers to the process of baking the bearing on the shaft, providing a spring retaining ring groove on the shaft or the shaft hole, and clamping the elastic retaining ring in the retaining ring groove to achieve axial fixation of the bearing and realize rotation; the articulation refers to a connection method that is achieved by performing activities on connecting parts such as hinges, pins and short shafts.

[0017] The present invention will be described in detail below with reference to the accompanying drawings. Example

[0018] The following is combined with Figure 1-3The present embodiment describes a ratchet clutch for protecting a double-sided motor, comprising: a transmission case 1, a shaft 2 being rotatably connected within the transmission case 1, the shaft 2 being connected to the power of one motor, a sleeve 3 being loosely fitted on the shaft 2, a transmission mechanism 4 being capable of transmitting the power of the other motor to the sleeve 3, a ratchet 5 being connected to the sleeve 3, the ratchet 5 being loosely fitted with the shaft 2, the ratchet 5 being engaged with the ratchet 6 via ratchet teeth, the ratchet 5 and the ratchet 6 being capable of only one-way transmission, the ratchet 6 being connected to the shaft 2, a spring 7 being sleeved on the shaft 2, the spring 7 being located between the inner wall of the transmission case 1 and the sleeve 3, and the spring 7 being in a compressed state;

[0019] When the equipment is running, the power of the motor on one side is transmitted to the sleeve 3 by the transmission mechanism 4, and the sleeve 3 drives the ratchet 1 5 to rotate. The power of the motor on one side is input by shaft 1 2, and shaft 1 2 drives the ratchet 2 6 to rotate. At this time, the two ratchets transmit power through the flat contact surface. The power of the two ratchets drives shaft 1 2 to rotate together, and then jointly drives the rotor of the equipment connected to shaft 1 2 to rotate, thereby improving the torque and equipment stability. When the equipment rotor reverses, the two ratchets stagger with each other along the contact inclined surface, and the reverse power will not be transmitted to the motor, thereby protecting the motor.

[0020] The transmission mechanism 4 includes a second shaft 41, which is connected to the motor power and is rotatably connected to the transmission box 1. The axes of the second shaft 41 and the first shaft 2 are located in different vertical planes. A sprocket 42 is connected to the second shaft 41 and the first shaft 2. The two sprockets 42 are connected by a chain 43, and the length of the chain 43 is left with a margin.

[0021] The staggered shaft 2 41 and shaft 1 2 allow transmission between the two sprockets 42 to be achieved using a loose chain 43. When the sleeve 3 drives the sprocket 42 to slide, the loose chain 43 can follow the tilt and be tightened, and the transmission will not be disconnected.

[0022] Two sprockets 42 are connected to the second shaft 41 and the first shaft 2 respectively. The four sprockets 42 and the two chains 43 form two sets of chain transmission;

[0023] Even if one set of belt transmission slips, the other set can still transmit stably, ensuring stable transmission.

[0024] In the description of the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention in specific circumstances.

[0025] The standard parts used in the present invention can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.
