Description

Technical Field

[0001] This utility model relates to the field of gearbox technology, and in particular to a quick-release gearbox. Background Technology

[0002] In industrial transmission equipment, the gearbox housing is typically composed of an upper shell and a lower shell that are fastened together. It houses core components such as gears and bearings. The reliability of its connection directly affects the transmission accuracy and sealing performance. In existing technologies, the gearbox housing is generally fixed using a fully bolted connection structure: multiple bolt holes are opened on the edges of the upper and lower shells, and a ring of evenly distributed bolts are tightened through to achieve fixation. Each maintenance requires loosening or tightening the bolts one by one, which is quite troublesome, especially in scenarios requiring frequent maintenance, and seriously affects maintenance efficiency. Based on the above situation, we designed a quick-release gearbox to solve the above problems. Utility Model Content

[0003] This invention provides a quick-release gearbox to solve the problem of cumbersome disassembly of the gearbox body in the prior art.

[0004] The technical problem solved by this utility model is achieved by the following technical solution:

[0005] A quick-release gearbox includes an upper housing and a lower housing that can be interlocked. Multiple quick-locking mechanisms are spaced apart at the interlocking edges of the upper and lower housings. Each quick-locking mechanism includes a swing locking member with one end hinged to the upper housing, and an eccentric protrusion at the other end. A locking groove corresponding to the eccentric protrusion is formed at the edge of the lower housing. By swinging the swing locking member, the eccentric protrusion can be engaged and disengaged from the locking groove. The gearbox also includes a positioning mechanism for secondary locking of the quick-locking mechanisms engaged in the locking groove.

[0006] Preferably, the positioning mechanism includes a positioning rod with one end hinged to the lower housing, a locking screw movably connected to the upper end of the positioning rod, and a locking hole that is threadedly engaged with the locking screw on the upper housing.

[0007] Preferably, the upper housing is provided with pre-insertion pins at the four corners, and the lower housing is provided with insertion holes corresponding to the pre-insertion pins.

[0008] Preferably, the end of the pre-insertion pin away from the upper housing is provided with a tapered guide portion.

[0009] Preferably, at least two sets of quick-locking mechanisms are provided at the long outer edges of the upper and lower housings.

[0010] Preferably, the swing locking member has a connecting groove that can fit against the outer wall of the positioning rod.

[0011] The beneficial effects of this utility model are as follows: by setting multiple sets of quick-locking mechanisms on the fastening edges of the upper and lower shells, the engagement or disengagement of the eccentric structure and the locking groove can be achieved simply by swinging the locking component, replacing the traditional all-bolt connection method. There is no need to tighten each bolt individually. The clamping force generated by the eccentricity of the eccentric structure ensures the tightness and stability of the connection after fastening. The fastening and disengagement of the upper and lower shells can be quickly completed by a simple swinging operation, reducing disassembly and assembly steps and time, and improving maintenance efficiency.

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0020] Reference Figures 1-5As shown, a quick-release gearbox includes an upper housing 1 and a lower housing 2 that can be interlocked. Multiple quick-locking mechanisms are spaced apart at the interlocking edges of the upper housing 1 and lower housing 2. Each quick-locking mechanism includes a swing locking member 3, one end of which is hinged to the upper housing 1. The swing locking member 3 is a long strip of metal rod, with one end hinged to an ear on the edge of the upper housing 1 via a pin. The pin axis is perpendicular to the interlocking surface of the upper housing 1, allowing the swing locking member 3 to swing up and down around the pin in a plane perpendicular to the interlocking surface. An eccentric protrusion 31 is provided at the other end of the swing locking member 3. A locking groove 32 corresponding to the eccentric protrusion 31 is provided at the edge of the lower housing 2. By swinging the swing locking member 3, the eccentric protrusion 31 can engage and disengage with the locking groove 32. The bottom is arc-shaped, and its curvature is consistent with the outer circle curvature of the eccentric protrusion 31. The groove opening is provided with an outward inclined guide slope, which makes it easy for the eccentric protrusion 31 to slide smoothly into the locking groove 32 when swinging. When actually fastening, the fastening edges of the upper housing 1 and the lower housing 2 are aligned, so that the eccentric protrusions 31 of each group of quick locking mechanisms are aligned with the locking groove 32 of the lower housing 2. The locking member 3 is swung downward, and the eccentric protrusion 31 slides into the groove along the guide slope of the locking groove 32. As the swing angle increases, the clamping force generated by the eccentricity of the eccentric protrusion 31 gradually increases until the swing locking member 3 drives the connecting surface of the upper housing 1 and the lower housing 2 to fit tightly. It also includes a positioning mechanism, which is used to perform secondary locking on the quick locking mechanism that is engaged in the locking groove 32.

[0021] Specifically, the positioning mechanism includes a positioning rod 4 hinged to the lower housing 2 at one end. A locking screw 41 is movably connected to the upper end of the positioning rod 4. A locking hole 42, threadedly engaged with the locking screw 41, is provided on the upper housing 1. After the swing locking member 3 drives the eccentric protrusion 31 into the locking groove 32, the positioning rod 4 is moved to a state parallel to the swing locking member 3 and comes into contact with it. Then, the locking screw 41 is screwed into the locking hole 42 to limit the movement of the swing locking member 3, thereby preventing the eccentric protrusion 31 from disengaging from the locking groove 32. The positioning rod 4 corresponds one-to-one with the swing locking member 3, while the locking screw 41 can correspond one-to-one with the positioning rod 4, or... Figure 1 As shown, a locking screw 41 is installed between adjacent positioning rods 4 via a cross plate.

[0022] Reference Figure 4As shown, the swing locking member 3 is further provided with a connecting groove 6 that can fit against the outer wall of the positioning rod 4. When the positioning rod 4 is in a vertical state parallel to the swing locking member 3, the positioning rod 4 is located in the connecting groove 6. If the positioning rod 4 is cylindrical, the cross section of the connecting groove 6 can be arc-shaped. If the positioning rod 4 is square, the cross section of the connecting groove 6 can be a corresponding square structure to increase the contact area between it and the swing locking member 3, so as to make its positioning effect on the swing locking member 3 better.

[0023] Reference Figure 2 as well as Figure 5 As shown, the upper housing 1 is further provided with pre-pins 5 at the four corners, and the lower housing 2 is provided with insertion holes 51 corresponding to the pre-pins 5. When the upper housing 1 and the lower housing 2 are connected, the pre-pins 5 are first inserted into the corresponding insertion holes 51 to limit the horizontal displacement of the upper housing 1 and the lower housing 2 after they are attached. This ensures that the eccentric protrusion 31 can accurately enter the locking groove 32 when connected by the quick locking mechanism. Furthermore, a tapered guide 52 is provided at the end of the pre-pin 5 away from the upper housing 1. When the upper and lower housings 2 are fastened, the tapered guide 52 can first contact the opening of the insertion hole 51. The relative position of the upper housing 1 and the lower housing 2 is automatically calibrated by the guiding effect of the tapered surface. Even if there is a slight offset, the pre-pin 5 can slide smoothly into the insertion hole 51 along the tapered surface to avoid installation obstruction due to alignment deviation.

[0024] Reference Figures 1-2 As shown, furthermore, at least two sets of quick-locking mechanisms are provided at the long outer edges of the upper shell 1 and the lower shell 2. When locking, in order to prevent uneven force on the upper shell 1 and the lower shell 2 due to one side being locked first, a diagonal locking method can be used. For example, first move the swing locking member 3 on one side, and then move the swing locking member 3 on the opposite side, so that the force on both sides is even. When both sides are locked, the forces will cancel each other out, and the shell will naturally remain centered. The short side of the shell can also be set to two sets according to the actual length of the shell and actual needs, and the diagonal locking method is also used.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
