Description

Technical Field

[0001] The invention relates to the technical field of worm gear reducers, and in particular to a worm gear reducer which is convenient for radial centering. Background Art

[0002] The reducer is an independent component consisting of a gear transmission, a worm transmission, and a gear-worm transmission enclosed in a rigid housing. It is often used as a reducer transmission device between the prime mover and the working machine and is widely used in modern machinery. In the actual selection and use process, due to economic and technical reasons, the reducer is not selected and installed according to the technical requirements, which greatly increases the probability of failure of the reducer. Due to its heavy load, high manufacturing precision, high maintenance difficulty and high cost, it has a great impact on the normal production of factories and enterprises. Therefore, it is one of the daily management of equipment to do a good job in the daily management of the reducer, improve the maintenance level, and maintain its good mechanical properties and normal operation.

[0003] Radial alignment refers to adjusting the relative position of the motor and reducer to achieve parallelism between the motor shaft end face and the reducer shaft end face.

[0004] The prior art discloses an automatic backlash-eliminating double-worm reducer of CN103335064B, comprising a housing, an upper worm, a lower worm, a worm box, a worm wheel, a flange shaft, and a brake disc. The upper and lower sides of the worm wheel are respectively provided with an upper worm and a lower worm meshing therewith, and the upper and lower sides of the worm wheel are symmetrical in structure. The worm is mounted in a worm box which can slide along the radial direction of the worm wheel through two tapered roller bearings. One end of the worm is connected to an elastic coupling after passing through the worm box. The right end shaft head of the flange shaft is directly mounted in the hole of the worm wheel and is tightened by a stop washer and a round nut. An oil seal is provided between the flange shaft and the housing. The brake disc is mounted on the right end shaft head of the flange shaft, and the electromagnetic coil is fixed to the housing. The worm gear is designed and assembled to ensure theoretically zero clearance. If there is a clearance during use, it can be automatically adjusted and eliminated. This can solve the problems of low shaft machining accuracy in the current four-axis or five-axis semi-closed-loop control system and insufficient process system rigidity of some machine tools due to reverse clearance. The double worm transmission has higher accuracy. During the use of the worm gear reducer, this device cannot easily and quickly perform radial alignment during the installation of the worm gear reducer, which can easily cause excessive force on one end face of the radial shaft, resulting in the risk of radial shaft breakage or unstable transmission. Therefore, we have made improvements to this and proposed a worm gear reducer that is easy to radially center. Summary of the invention

The outer end of the fork rod 13 is provided with a clamping hole 16, and the clamping hole 16 is embedded in the inner surface of the tail end of the annular groove 18.

[0052] The double-cone magnetic block 12 and the annular groove 18 are adsorbed by the magnetic belt, so that the linkage spring 10 can be stretched, and under the action of stretching the linkage spring 10, the corresponding fork rod 13 is driven to expand outward.

[0053] When the double-cone magnetic block 12 located at the outer end of the positioning rod 11 at the lower end of the first linkage seat 6 and the annular groove 18 are magnetically attracted to each other, the fork rod 13 at both ends is squeezed by the double-cone magnetic block 12, and the fork rod 13 is inserted into the corresponding card hole 16 through the mutual squeezing of the limit tube 15 and the limit spring 14, so as to ensure stability between the radial linkage assembly and the motor 2 under the action of magnetic adsorption.

The outer end of the adjustment threaded rod 21 is movably connected to the linkage inclined rod plate 22, and the linkage inclined rod plate 22 is fixedly installed on the front end outer surface of the motor 2.

[0056] Through the activities between the linkage inclined rod plate 22 and the adjusting threaded rod 21 , it can be ensured that the linkage inclined rod plate 22 drives the corresponding motor 2 to adjust the position up and down, thereby fine-tuning the position of the corresponding radial shaft 3 .

[0057] The outer end of the linkage rod 23 is movably connected to the rotating short rod 27 through a rotating groove 26.

[0063] First, the U-shaped rod 30 can facilitate the placement of the end box 36 therein;

[0064] Secondly, the vial 35 in the end box 36 is connected by the end rod 34 to ensure stable leveling of the vial 35 .

[0065] By positioning the U-shaped rod 30 at the upper end of the motor 2, the adjusting rod 31 located at the upper end of the reduction motor 1 is connected through the linkage between the protrusion 33 and the groove 32.

At this time, the adjusting threaded rod 21 located in the reduction motor 1 and the linkage inclined rod plate 22 in the motor 2 are linked to each other, so that the motor 2 can drive the corresponding radial axis 3 to be fine-tuned upward, so as to stabilize the radial axis 3 between the reduction motor 1 and the motor 2 and prevent excessive local force from causing the radial axis 3 to break; by positioning the U-shaped rod 30 at the upper end of the motor 2, the adjusting rod 31 located at the upper end of the reduction motor 1 is connected through the linkage between the protrusion 33 and the groove 32.
