Description

Technical Field

[0001] This utility model relates to the field of crane reducer technology, specifically a crane reducer that can prevent unstable housing support. Background Technology

[0002] When using a crane to lift goods, a speed reducer is needed to match the torque between the crane and the power source. Crane speed reducers are relatively large, and to ensure stable installation and balance, a base is installed at the bottom of the speed reducer, and the two must be horizontally connected; otherwise, the support will be unstable. The connection between the speed reducer and the base is currently quite simple, typically using high-strength bolts. However, the speed reducer vibrates during operation, causing lateral and vertical tension on the fixing bolts, leading to loosening of the bolts. In severe cases, this can cause bolt deformation or even breakage, resulting in the speed reducer tipping over. Utility Model Content

[0018] Please see Figure 1-3 This utility model provides a technical solution: a crane reducer that prevents unstable shell support, comprising a reducer housing 1 and a support base 2. The support base 2 is located on both sides of the reducer housing 1. The lower sides of the reducer housing 1 are provided with snap-fit ​​blocks 6 for positioning and limiting the Y-axis direction. The lower ends of the reducer housing 1 are fixedly connected to positioning blocks 8 for positioning and limiting the X-axis direction. The side ends of the support base 2 are provided with pad grooves 14 and stabilizing protrusions 10. A support pad 12 is inserted between the two support bases 2, and the support pad 12 is used to connect the two support bases 2. The support plate 12 has a plate head 13 on both sides, and a concave space is formed between the two support bases 2. The lower end of the support base 2 is provided with a fixing bolt 3. The fixing bolt 3 is located in the concave space, which facilitates the connection of the fixing bolt 3. Two stabilizing strips 7 are provided between the support plate 12 and the reducer housing 1. The upper end of the fixing bolt 3 is threadedly connected to the stabilizing strip. The stabilizing strip 7 is used to provide stable support for the reducer housing 1. The side end of the stabilizing strip 7 is provided with a stabilizing groove 17. A buffer rubber pad 4 is provided between the two stabilizing strips 7. The buffer rubber pad 4 can buffer the vibration generated by the reducer operation.

[0019] The side end of the pad head 13 is an arc-shaped structure. The lower end of the pad head 13 is lower than the lower end surface of the support pad 12. The two ends of the fixing bolt 3 penetrate the support pad 12. The pad head 13 and the pad groove 14 are interlocked to restrict the support pad 12 and the support base 2 in the X-axis direction, so that the two support bases 2 are connected together and fixed by the fixing bolt 3.

[0020] Both the stabilizing protrusion 10 and the stabilizing slot 17 have arc-shaped sides. The stabilizing protrusion 10 is inserted into the stabilizing slot 17. The upper end of the stabilizing protrusion 10 is provided with a blocking slot 9. A blocking plate 16 is fixedly connected to the upper inner wall of the stabilizing slot 17. The blocking plate 16 is inserted into the blocking slot 9. The lower inner wall of the stabilizing slot 17 is provided with a reinforcing groove 18. The lower end of the stabilizing protrusion 10 is provided with a reinforcing protrusion 11. The reinforcing protrusion 11 is located at the reinforcing groove 18. After the stabilizing strip 7 and the stabilizing protrusion 10 are inserted, the support base 2 restricts the X-axis and Z-axis directions of the stabilizing strip 7. The stabilizing strip 7 supports the bottom of the reducer housing to ensure the stability of the reducer housing 1.

[0021] The upper end of the stabilizing strip 7 is provided with a positioning groove 15, and the positioning block 8 is inserted into the positioning groove 15. The lower end of the positioning block 8 has an arc-shaped structure, which restricts the X-axis and Y-axis directions of the stabilizing strip 7 and the reducer housing 1, so as to prevent misalignment between the stabilizing strip 7 and the reducer housing 1.

[0022] The side end of the support pad 12 is provided with a vertical groove 5. The upper inner wall of the vertical groove 5 is inclined. The upper side wall of the snap block 6 is also inclined. When the support base 2 and the reducer housing 1 are connected, the vertical groove 5 presses the snap block 6, thereby restricting the Z-axis direction of the reducer housing 1.
