Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of gear boxes, in particular to a staggered gear speed reducer. Background Art
[0002] A gearbox is a mechanical device used to transmit power and speed. It consists of multiple components such as an input shaft, an output shaft, gears, bearings, and a housing. It transmits power through the meshing and rotation of gears. It is widely used in manufacturing, transportation, construction, and other fields, and is an important component in most mechanical equipment.
[0003] Currently, there are only two ways to use the input and output at 90°: one is to use a worm gear structure; the other is to use a cam roller worm structure. These two structures, while achieving high precision, are difficult to miniaturize and process, with high costs, making it difficult to meet the requirements of use in a small space. Utility Model Content
[0004] The technical problem to be solved by the utility model is that the traditional 90° input and output transmission structure is difficult to manufacture and has high cost.
[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is as follows: a staggered gear speed reducer, comprising a box body, wherein the box body is divided into an upper cavity and a lower cavity connected to each other;
[0006] The upper cavity is penetrated by a rectangular inner cavity, and a driven gear shaft is arranged in the rectangular inner cavity. A driven gear is fastened with a sleeve on the center of the driven gear shaft. Connecting plates are fastened on both sides of the upper cavity. The two ends of the driven gear shaft pass through two connecting plates respectively. The connecting plates are equipped with a deep groove ball bearing sleeved on the driven gear shaft. A cover plate is provided on one side of the deep groove ball bearing that is fastened to the connecting plate.
[0007] The lower cavity is provided with a disc-shaped inner cavity connected to the rectangular inner cavity. A driving gear is engaged with a 45-degree staggered driving gear below the driven gear, and the driving gear is fixedly sleeved on the driving gear shaft. Two deep groove ball bearings are fixedly sleeved at both ends of the driving gear shaft. A threaded cover is fastened to one side of the lower cavity.
[0008] As a further improvement of the present invention, a threaded cover 2 is provided between the deep groove ball bearing 1 and the cover plate, and the threaded cover 2 is threadedly connected to the cover plate.
[0009] As a further improvement of the present invention, a dustproof gasket is fixedly provided on the inner side of the cover plate.
[0010] As a further improvement of the present invention, one side of the lower cavity is fastened with a top cover by a plurality of bolts, and the top cover is engaged with the deep groove ball bearing.
[0011] As a further improvement of the present invention, machine-made rice top screws are provided on both sides of the top of the upper cavity.
[0012] The beneficial effects of the present invention are as follows: since small-module worm gears are difficult to process and costly to manufacture, it is difficult to reduce the processing difficulty and manufacturing cost of the gears when high precision needs to be maintained. The 45° staggered helical teeth are made into a gearbox, which can effectively replace some application scenarios of the worm gear reducer, and can be applied to narrow and limited-position working scenarios, thereby improving the stability and efficiency of the structural operation and the utilization rate of the working space.

It should be understood that the implementation methods described herein are only used to explain this application and are not intended to limit this application.
[0019] The utility model provides a staggered gear accelerator, comprising a box body 1, which is divided into an upper cavity and a lower cavity which are connected to each other;
[0020] As attached Figure 1-2As shown, the upper cavity is formed with a rectangular inner cavity, within which a driven gear shaft 2 is mounted. A driven gear is securely mounted on the center of the driven gear shaft 2. Connecting plates 3 are secured to both sides of the upper cavity. Driven gear shaft 2 extends through two connecting plates 3 at each end. These plates are fitted with deep groove ball bearings 1 and 4, which fit over the driven gear shaft 2. One side of the connecting plates 3 has mounting slots for deep groove ball bearings 1, which are 688 deep groove ball bearings. A cover plate 5, secured to the deep groove ball bearings 4, is secured to the connecting plates 3. A threaded cap 2 10 is threadedly connected to the cover plate 5 between the deep groove ball bearings 4 and the cover plate 5. When tightened, these caps 10 prevent movement of the deep groove ball bearings 4. A dustproof ring is fixed to the inside of the cover plate 5 to prevent foreign matter and dust from entering the device. A set screw 11 is located on either side of the top of the upper cavity; these screws adjust the radial mounting distance of the driven gear.
[0021] As attached Figure 1-2 As shown, the lower cavity has a disc-shaped cavity connected to the rectangular cavity. A driving gear 7 is meshed below the driven gear, staggered at 45 degrees. The driving gear 7 is fixedly sleeved on the driving gear shaft. Deep groove ball bearings 6 are fixedly sleeved on both ends of the driving gear shaft. The deep groove ball bearings 6 are 61801 deep groove ball bearings. A threaded cap 9 is fastened to one side of the lower cavity. A top cap 8 is fastened to one side of the lower cavity by multiple bolts. The top cap 8 is embedded in the deep groove ball bearings 6; the top cap 8 serves to limit and fix the driving gear 7 to prevent it from moving.
[0022] Working principle: In the specific implementation of the present invention, the driven gear and the driven gear shaft 2 are first passed through the upper cavity of the box body 1, and the deep groove ball bearing 4 is assembled into the mounting groove of the connecting plate 3.
