Description

Technical Field

[0001] The utility model relates to the technical field of reducers, in particular to an improved reducer sealing box. Background Art

[0002] By using a sealing box to seal the reducer and the outside of the gear transmission box, the flange connection can be protected while achieving sealing, isolating the reducer from the working environment, reducing the impact of a poor working environment on the reducer, and using a sealing box can make the reducer work more stably.

[0003] In the prior art, a Chinese patent with authorization announcement number CN219809391U discloses a sealed housing for a worm gear reducer, which solves the problem that the sealed housing of the reducer has poor heat dissipation effect, cannot dissipate heat in time, and is easy to damage the reducer, affecting its use. The reducer includes a reducer housing, the outside of which is sealed and connected to a shell, a cavity is provided between the reducer housing and the shell, a heat dissipation component is connected to one side of the outside of the shell, a circulating water pump transports cold water in the water tank to the inside of the cavity through a water pipe, so that the reducer housing contacts the cold water, and the heat emitted by the reducer housing is absorbed by the cold water. Under the continuous circulation of the circulating water pump, the cold water in the cavity continuously flows, thereby better absorbing the heat of the reducer housing, cooling it, and achieving the heat dissipation effect, thereby avoiding the heat generated by the reducer housing during operation and being unable to dissipate heat in time, causing damage and affecting its use.

[0004] The above mechanism uses a box to seal and protect the reducer, and uses a water pump to continuously transport cooling water to achieve cooling and heat dissipation. However, in actual use, the external box has a weakened effect on the heat dissipation of the reducer. At the same time, due to the harsh working environment of the reducer, the flange sealing method is prone to oil leakage but cannot be promptly reminded. Utility Model Content

[0012] Furthermore, the sealing mechanism includes a second airbag, and the alarm box is fixedly connected to the inside of the upper cover of the sealing box, the bottom end of the second airbag is fixedly connected to the first airbag through a hose, and the first airbag is fixedly connected to the upper end of the outer side of the lower box body of the sealing box.

[0013] Furthermore, clamping blocks are arranged on both sides of the limit frame, and clamping grooves matching the clamping blocks are opened on both sides of the limit frame, and connecting springs are wound around the outer sides of the clamping blocks.

[0014] Furthermore, the top of the inner part of the limiting frame and the top of the limiting ring are both fixedly connected with electromagnets, and the positions of the electromagnets correspond to each other.

[0017] Furthermore, the upper cover of the sealed box and the lower box of the sealed box are engaged with each other, so that the upper cover of the sealed box and the lower box of the sealed box can protect the flange from the outside, thereby preventing the flange from being damaged due to accidental collision during use. The protection is achieved by the cooperation of the upper cover of the sealed box and the lower box of the sealed box, and at the same time, dirt is reduced from entering the connection gap of the flange.

[0018] Furthermore, the gas inside the second airbag is transported to the inside of the first airbag through the hose, so that the first airbag seals and wraps the outer side of the lower box body of the sealed box from both inside and outside, reducing the gap between the upper cover body of the sealed box and the lower box body of the sealed box, achieving better sealing protection, and reducing the possibility of impurities entering the upper cover body of the sealed box and the lower box body of the sealed box;

[0030] Embodiment 1:

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 The technical solution shown is to solve the problem that due to the harsh working environment of the reducer, the flange sealing method is prone to oil leakage but cannot be promptly reminded: the improved reducer sealed box body discloses an alarm mechanism, including a reducer body 1, one side of the reducer body 1 is fixedly connected to a transmission box 2 through a flange 5, the outer upper end of the flange 5 is sleeved with a sealed box upper cover 3, and the bottom end of the sealed box upper cover 3 is snap-connected with a sealed box lower box body 4, the bottom end of the sealed box lower box body 4 is fixedly connected with an alarm box 6, and the interior of the alarm box 6 is provided with an alarm mechanism for lubricating oil leakage reminder, the alarm mechanism includes a fixed plate 10, and the fixed plate 10 is fixedly connected to the interior of the alarm box 6, the fixed plate 10 A baffle plate 12 is arranged above the baffle plate 12, the top of which is fixedly connected to the sponge layer 7, and the baffle plate 12 is snap-connected to the bottom end of the lower box body 4 of the sealed box, the bottom end inside the alarm box 6 and both sides of the bottom end of the fixed plate 10 are fixedly connected to conductive sheets 11, and the positions of the conductive sheets 11 correspond to each other, and guide rods 8 are fixedly connected to both sides of the bottom end of the baffle plate 12, the bottom end of the baffle plate 12 is fixedly connected to a return spring 9, and the bottom end of the return spring 9 is connected to the fixed plate 10, the bottom end of the guide rod 8 passes through and extends to the bottom end of the fixed plate 10, the guide rod 8 is arranged inside the return spring 9, the sponge layer 7 is arranged below the flange 5, and the baffle plate 12 is slidably connected to the lower box body 4 of the sealed box.

[0032] In this example, the reducer body 1 and the transmission shaft of the transmission box 2 are connected by flange 5. After the connection, when the lubricating oil leaks between the flanges 5, the lubricating oil will drip onto the sponge layer 7. The sponge layer 7 can be used to collect the dripping lubricating oil. When the dripping lubricating oil reaches a certain amount, the weight of the sponge layer 7 will increase, and the sponge layer 7 will be stressed and move downward, so that the reset spring 9 at the bottom of the sponge layer 7 is stressed and shortened. At the same time, the guide rod 8 inside the reset spring 9 is pushed by the sponge layer 7, and the conductive sheets 11 at the bottom of the sponge layer 7 contact each other to achieve signal transmission, reminding the staff to promptly inspect the flange 5 at that location to prevent excessive leakage of the lubricating oil.
