Description

Technical Field

[0001] This utility model relates to the field of speed reducer technology, specifically to a heavy-duty, anti-loosening hardened gear speed reducer. Background Technology

[0002] Hardened gear reducers are relatively precise machines used to reduce speed and increase torque. They are suitable for high-speed shaft speeds not exceeding 1500 rpm, gear transmission circumferential speeds not exceeding 20 m / s, and operating environments with temperatures ranging from -40°C to 45°C.

[0003] For example, existing patent CN208281433U discloses a spiral bevel gear hardened tooth surface reducer. The cover is fixed to the housing by bolts. Inside the housing cavity are an input bevel gear, an output bevel gear, an L-shaped plate, and a cycloidal reduction device. The input bevel gear is fixed to the input shaft, which passes through the housing and connects to an external drive motor. The input bevel gear is connected to the output bevel gear through gear meshing, and the output bevel gear is connected to the cycloidal reduction device through an intermediate shaft. However, in the aforementioned patent, the housing and cover of the hardened tooth surface reducer are connected by bolts. During use, the hardened tooth surface reducer generates continuous vibration. Prolonged exposure to this vibration causes the bolts to loosen, creating gaps between the housing and cover, which affects the internal components of the reducer.

[0004] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a heavy-duty anti-loosening hardened tooth surface reducer to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A heavy-duty anti-loosening hardened gear reducer includes a base plate and a lower housing located on top of the base plate. An upper housing is provided on top of the lower housing. Anti-loosening pressure blocks are symmetrically arranged on both sides of the top of the upper housing. The anti-loosening pressure blocks are provided with an anti-loosening mechanism connected to the base plate on top. Mounting plates are provided at the bottom corners of the lower housing. Bolts connected to the base plate are provided on the mounting plates.

[0008] Preferably, the anti-loosening mechanism includes a connecting column vertically arranged at the top of the anti-loosening pressure block, and a connecting plate is provided at the top of the connecting column.

[0009] Preferably, the top of the substrate is provided with a symmetrically arranged bracket 1 and bracket 2, each of which is movably provided with a threaded rod, and the bottom of the two sets of threaded rods are respectively movably connected to the two sets of connecting plates.

[0010] Preferably, the top of the threaded rod is provided with a rotating handle, and the first bracket and the second bracket are provided with threaded holes for threaded connection of the threaded rod.

[0011] Preferably, the top two sides of the connecting plate are symmetrically provided with guide rods that correspondingly and movably pass through the first bracket and the second bracket.

[0012] Preferably, the connection between the mounting plate and the bolt is provided with an anti-loosening clamp, and the bottom of the anti-loosening clamp is provided with a rubber pad.

[0013] The beneficial effects of this utility model are as follows: by setting the anti-loosening pressure block and the anti-loosening mechanism, the position of the upper shell is fixed. The anti-loosening pressure block contacts the top of the upper shell, which can fix the upper shell and prevent the vibration generated by the operation of the reducer from causing the fixing bolts connecting the lower shell and the upper shell to loosen, so as to create a gap between the lower shell and the upper shell, affecting the normal operation of the reducer and making the equipment run more stably.

The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0020] According to an embodiment of the present invention, a heavy-duty anti-loosening hardened gear reducer is provided.

[0021] Example 1:

[0022] like Figure 1-2 As shown, the heavy-duty anti-loosening hardened gear reducer according to an embodiment of the present utility model includes a base plate 1 and a lower housing 2 located on the top of the base plate 1. An upper housing 3 is provided on the top of the lower housing 2. Anti-loosening pressure blocks 4 are symmetrically arranged on both sides of the top of the upper housing 3. An anti-loosening mechanism connected to the base plate 1 is provided on the top of the anti-loosening pressure block 4. Mounting plates 5 are provided at the bottom corners of the lower housing 2. Bolts 6 connected to the base plate 1 are provided on the mounting plates 5.

[0023] Example 2:

[0024] like Figure 1-2 As shown, the anti-loosening mechanism includes a connecting column 7 vertically arranged at the top of the anti-loosening pressure block 4. The top of the connecting column 7 is provided with a connecting plate 8. The top of the base plate 1 is provided with a symmetrically arranged bracket 1 9 and bracket 2 10. Each of the bracket 1 9 and bracket 2 10 is movably provided with a threaded rod 11. The bottom of the two sets of threaded rods 11 is movably connected to the two sets of connecting plates 8 respectively. The top of the threaded rod 11 is provided with a handle 12. The bracket 1 9 and bracket 2 10 are provided with threaded holes for threaded connection of the threaded rod 11.

[0025] Example 3:

[0026] like Figure 1-2 As shown, the top two sides of the connecting plate 8 are symmetrically provided with guide rods 13 that move through the bracket 1 9 and the bracket 2 10. The connection between the mounting plate 5 and the bolt 6 is provided with an anti-loosening clamping plate 14, and the bottom of the anti-loosening clamping plate 14 is provided with a rubber pad.

[0027] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0028] In practical applications, rotating the handle 12 drives the threaded rod 11 to rotate and move downward. The threaded rod 11 drives the connecting column 7 to move downward synchronously through the connecting plate 8. The connecting column 7 drives the anti-loosening pressure block 4 to contact the top of the upper housing 3, which can fix the upper housing 3 and prevent the vibration generated by the operation of the reducer from causing the fixing bolts connecting the lower housing 2 and the upper housing 3 to loosen, resulting in a gap between the lower housing 2 and the upper housing 3, which would affect the normal operation of the reducer.

[0029] In summary, by means of the above-mentioned technical solution of this utility model, the position of the upper housing 3 is fixed by setting the anti-loosening pressure block 4 and the anti-loosening mechanism. The anti-loosening pressure block 4 contacts the top of the upper housing 3, which can fix the upper housing 3 and prevent the vibration generated by the operation of the reducer from causing the fixing bolts connecting the lower housing 2 and the upper housing 3 to loosen, so as to create a gap between the lower housing 2 and the upper housing 3, which would affect the normal operation of the reducer and make the equipment operation more stable.
