Description

Technical Field

[0001] This utility model relates to the field of worm gear box housing technology, and in particular to worm gear box casting housing. Background Technology

[0002] A worm gearbox is a device used to convert axial or radial force into torque, commonly used in gear transmission systems. A worm gearbox consists of a toothed driving gear and a toothed driven gear, which mesh to generate torque. Worm gearboxes are mostly encased in a cast housing, whose main function is to protect internal components such as gears and bearings, while also providing support and a mounting position. In existing technologies, the cast housings used for worm gearboxes are mostly assembled in two parts, upper and lower. However, when assembling the worm gearbox with the lower housing, due to the numerous and precise components of the worm gear, the operator needs to reach into the lower housing for installation, which is very inconvenient for quickly assembling the worm gearbox with the lower housing. Therefore, we propose a new type of cast housing for worm gearboxes. Utility Model Content

[0003] The purpose of this invention is to address the problems existing in the background technology by proposing a casting housing for a worm gear box.

Detailed Implementation

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. Example

[0020] like Figure 1-3As shown, the worm gear box casting housing proposed in this utility model includes an upper shell 1, a first split shell 2, and a second split shell 3. Two sets of lifting rings 4 are provided on the upper shell 1, with the mounting ends of the lifting rings 4 corresponding to the upper part of the upper shell 1 and fixedly connected to the upper part of the upper shell 1. The lifting rings 4 facilitate the operator's lifting and transport of the worm gear box using a crane. An insert plate 5 is provided on one side of the first split shell 2, with the mounting ends of the insert plate 5 corresponding to one side of the first split shell 2 and fixedly connected to one side of the first split shell 2. A plate groove 7 is provided on one side of the second split shell 3, with the plate groove 7 corresponding to the insert plate 5. The insert plate 5 and the plate groove 7 fit together. When the first split shell 2 and the second split shell 3 are assembled, the insert plate 5 is inserted into the plate groove 7. The groove 7 is slidably connected. Multiple sets of rod holes 6 are opened on the upper side of the split shell 2 near the insert plate 5. Multiple sets of guide rods 8 are set on the upper side of the split shell 3 near the plate groove 7. The mounting end of the guide rod 8 is installed corresponding to one side of the split shell 3. The mounting end of the guide rod 8 is fixedly connected to one side of the split shell 3. The guide rod 8 is installed corresponding to the rod hole 6. When the split shell 2 and the split shell 3 are in the assembled state, the guide rod 8 is inserted into the rod hole 6. The mutual cooperation of the insert plate 5 and the plate groove 7, the guide rod 8 and the rod hole 6 can make the split shell 2 and the split shell 3 more stable when they are in the assembled state. The split-shaped arrangement of the upper shell 1, the split shell 2 and the split shell 3 makes it easy for the operator to quickly assemble the worm gear box, and also facilitates subsequent inspection and maintenance, greatly improving work efficiency.

[0021] When the two separate housings 2 and 3 are installed, they fit tightly against each other on one side. They can be assembled into a single unit, allowing for better adaptation to the worm gearbox. Multiple sets of fastening mechanisms 9 are provided on both sides of the two separate housings 2 and 3. Each set of fastening mechanisms 9 includes two sets of positioning seats 91, which are respectively installed on the opposite side of the two separate housings 2 and 3. The mounting ends of the positioning seats 91 are fixedly connected to one side of the two separate housings 2 and 3. A fastening bracket 92 is provided between the two sets of positioning seats 91, with each end of the fastening bracket 92 connected to one of the positioning seats 91. The positioning base 91 is installed accordingly, and the inner wall of the fastening bracket 92 is respectively in contact with the split shell 1 2 and split shell 2 3. Each positioning base 91 has a fastening bolt 93 on one side. The split shell 1 2 and split shell 2 3 are provided with pin holes 15 near the positioning base 91 and the fastening bracket 92. The fastening bolt 93 is installed in correspondence with the pin hole 15 and is threadedly connected to the pin hole 15. The setting of the fastening bolt 93 can make the split shell 1 2 and split shell 2 3 more stable through the positioning base 91 when the fastening bracket 92 is installed, thereby avoiding the separation of the split shell 1 2 and split shell 2 3 when the worm gear box is in operation.

[0022] Multiple sets of arc-shaped grooves 10 are formed on the upper shell 1, split shell 1 2, and split shell 2 3. These arc-shaped grooves 10 are distributed along the outer sides of the upper shell 1, split shell 1 2, and split shell 2 3 respectively. Multiple sets of heat dissipation holes 11 are formed on the inner wall of each arc-shaped groove 10. The combination of multiple arc-shaped grooves 10 and multiple sets of heat dissipation holes 11 can better dissipate heat and cool the worm gear box inside the shell. Multiple sets of reinforcing ribs 12 are provided on the inner bottom of split shell 1 2 and split shell 2 3. The mounting ends of the reinforcing ribs 12 are fixedly connected to the inner sides of split shell 1 2 and split shell 2 3 respectively. The reinforcing ribs 12 can improve the cooling effect of split shell 1 2 and split shell 2 3. To enhance the overall strength of shell 2 3, multiple sets of fixing bolts 13 are installed on the mounting end of upper shell 1 and above split shell 1 2 and split shell 2 3. Screw holes are provided on the mounting end of upper shell 1 and above split shell 1 2 and split shell 2 3. The fixing bolts 13 are installed corresponding to the screw holes and are threadedly connected to them. The fixing bolts 13 allow for quick and stable assembly of split shell 1 2 and split shell 2 3 with upper shell 1. Multiple sets of fixing bolt holes 14 are provided on the mounting ends of split shell 1 2 and split shell 2 3. The fixing bolt holes 14 allow for proper fitting and fixing of split shell 1 2 and split shell 2 3 to the mounting platform when they are in the assembled state.

[0023] In this embodiment, when the operator needs to assemble the worm gear box, firstly, the mounting end of the worm gear box is fitted and installed to the inner side of the split shell 2. Then, the operator wraps and protects the other side of the worm gear box with the split shell 3. At this time, the split shell 3 drives the guide rod 8 to insert into the rod hole 6 on the split shell 2, and at the same time, the insert plate 5 is inserted into the plate groove 7, so that the split shell 2 and the split shell 3 are in a tight fit. Then, the operator fastens the fastening bracket 92 to the positioning seat 91 on one side of the split shell 2 and the split shell 3, and then locks it with the fastening bolt 93, thereby completing the assembly operation of the split shell 2 and the split shell 3 with the worm gear box. Then, the operator assembles the upper shell 1 onto the top of the worm gear box, so that the lower part of the upper shell 1 corresponds to the upper part of the split shell 2 and the split shell 3. Then, the fixing bolt 13 is used to fix the split shell 2 and the split shell 3 to the upper shell 1, thereby completing the assembly operation of this device with the worm gear box.

[0024] The above-described specific embodiments are merely preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above-described specific embodiments.
