Description

Technical Field

[0001] This utility model relates to the field of passive bevel gear technology, specifically to a passive bevel gear with a split structure. Background Technology

[0002] In the field of mechanical transmission, bevel gear transmissions are widely used in numerous mechanical equipment due to their significant advantages, such as the ability to achieve commutation, high overlap ratio, smooth transmission, low noise, and high load-bearing capacity. These include general-purpose reducers (dby series, dcy series, etc.). As a key component in bevel gear transmission systems, the performance and structural design of the driven bevel gear play a crucial role in the overall operation of the transmission system.

[0003] Currently, Chinese utility model patent application number 202222002084.5 discloses a split gear for a speed reducer, which splits the gear into two semi-circular gears. Each semi-gear has a corresponding locking block and slot on its mating surface, and the two semi-gears are connected by bolts. When replacing the gears, it is not necessary to disassemble the entire drive shaft, which improves the convenience of operation and reduces repeated installation errors. However, the two semi-gears are only connected by two bolts. During the operation of the speed reducer, the bolts are easy to fall off, and the circumferential force between the two semi-gears can easily cause the bolts to wear, deform, or even shear off, resulting in connection failure. Utility Model Content

[0004] Technical problems to be solved

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a passive bevel gear with a split structure, which can effectively solve the problems in the existing technology.

[0006] Technical solution

[0007] This utility model provides a split-structure passive bevel gear, including a left block and a right block, which are fixedly connected by splicing. The front ends of the left and right blocks are provided with annular tooth grooves and front threaded holes. A front fixing frame is inserted and fixed in the annular tooth groove. The front fixing frame is engaged and fixed with the front threaded hole by a front threaded rod. The rear ends of the left and right blocks are provided with rear annular grooves, and rear threaded holes are provided in the rear annular grooves. A rear fixing frame is placed in the rear annular grooves, and the rear fixing frame is engaged and fixed with the rear threaded hole by coarse bolts and fine bolts.

[0008] Furthermore, both the front-end fixing frame and the rear-end fixing frame are annular structures, and both have a circular hole in the middle. Both the front-end fixing frame and the annular toothed groove are toothed structures with matching dimensions, and the rear-end fixing frame has multiple sets of toothed holes equidistantly arranged inside.

[0009] Furthermore, the rear threaded hole is divided into a coarse threaded hole and a fine threaded hole in the rear annular groove, and the coarse threaded hole is opened at the edge of the left block and the right block, and a washer is sleeved on the outside of the coarse bolt.

[0010] Furthermore, both the left and right blocks are half-structures of bevel gears, and protrusions and grooves are symmetrically arranged on their side walls.

[0011] Furthermore, the front threaded rods are distributed in an equidistant array on the front end fixing frame, and the thin bolts are arranged in an equidistant array on the rear end fixing frame.

[0012] Furthermore, anti-slip buffer pads are provided on the contact surfaces of the left and right blocks.

[0013] Beneficial effects

[0014] This utility model, through its left-right block and its combined structure, allows users to connect the left and right blocks via a front-end fixing frame and a rear-end fixing frame to form a unified whole. When used together, the front-end fixing frame uses a front threaded rod to engage with the front threaded hole in the annular toothed groove, achieving the combined function through the toothed structure. Similarly, at the rear end, the rear-end fixing frame uses coarse and fine bolts to engage with the rear threaded hole in the rear annular groove. Combined with the front-end structure, this achieves a unified front-to-rear combination, improving structural strength during use, preventing damage to the buckle plate from radial shear forces, and enhancing the stability of the two half-gear connections.

[0015] In this device, through the designed protrusion and groove structure, the user can mate the protrusion in the left block with the groove in the right block, and the protrusion in the right block can also mate with the groove in the left block to achieve a preliminary combination function. Therefore, in use, in conjunction with the front and rear side structures, the stress on a single connecting part is reduced, the risk of bolt damage is reduced, and the stability of the connection between the two half gears is improved.
