Description

Technical Field

[0001] The utility model relates to the technical field of maintenance tools, and particularly relates to a special barring tool for an elastic sleeve pin coupling. Background Technique

[0002] The elastic sleeve pin coupling is a type of coupling widely used in the field of mechanical transmission. It is mainly used to connect two shafts (the driving shaft and the driven shaft) in different mechanisms, enabling them to rotate together to transmit torque. Its unique design and working principle play an important role in power transmission. The working principle of the elastic sleeve pin coupling is based on the elasticity of the elastic sleeve and the positioning function of the pin. When the two half couplings are respectively connected to the two shafts that need to be transmitted, through the interaction of the elastic sleeve and the pin, the connection and torque transmission between the two shafts are realized. While transmitting torque, the elastic sleeve can absorb and buffer the vibration and impact generated during the transmission process, protecting the transmission system from damage. It has the following characteristics:

[0003] Buffer and shock absorption: The elastic sleeve pin coupling has a certain buffering and shock absorption function, which can effectively reduce the vibration and impact during the transmission process, protecting the transmission system and its components from damage;

[0004] Compensation for displacement: Due to the elastic deformation ability of the elastic sleeve, this coupling can compensate for the relative displacement and deviation between the two shafts, improving the stability and reliability of the transmission system;

[0005] Widely used: The elastic sleeve pin coupling is widely used in various mechanical transmission systems, such as in equipment like fans, water pumps, compressors, and speed reducers. Especially in transmission systems that need to withstand large vibrations and impacts, its advantages are more obvious.

[0006] The inventor found the following problems in the prior art that have not been well solved during the implementation of this solution:

[0007] The coupling cannot be turned manually: When the outer diameter of the coupling reaches or exceeds 300 mm, it usually means that the mechanical equipment it connects is relatively large and the transmitted torque is also relatively large. Therefore, in the stopped state, it may be very difficult or even impossible to manually rotate such a large coupling by relying solely on human strength;

[0008] When using a crowbar to turn the coupling, it is not firmly fixed: To solve the problem of difficult manual barring, sometimes tools such as crowbars are used to assist in barring. However, when the coupling is large in size, the force application point of the crowbar may be difficult to stably fix. Especially in the absence of a special fixture or support structure, this instability may cause the crowbar to slide or shift during the barring process, thus affecting the barring effect;

[0009] Easy to loosen and slip: Due to the unstable fixation of the crowbar and the possible vibration and impact force during barring gear operation, the crowbar is very likely to loosen or slip from the force application point. This situation will not only cause the interruption of barring gear operation, but more importantly, it may lead to mechanical injury accidents. For example, the loose crowbar may injure the operator, or the slipping crowbar may hit other equipment components and cause damage.

[0010] Cause mechanical injury: The above-mentioned unstable situations such as loosening and slipping directly threaten the safety of the operator. In a working environment with dense mechanical equipment, once an accident occurs, the consequences may be very serious. Therefore, during the maintenance process, this type of potential risk must be highly regarded, and corresponding safety measures should be taken to prevent the occurrence of accidents.

[0011] In summary, in order to avoid the above problems, the present application proposes a special barring gear tool for an elastic sleeve pin coupling. Summary of the Utility Model
