Description

Technical Field

[0001] The utility model relates to the field of speed reduction equipment, in particular to a durable worm gear speed reducer. Background Art

[0002] The worm gear reducer is a commonly used reduction transmission device. Its transmission principle is mainly to achieve deceleration by friction transmission between the worm and the worm wheel. The worm is a cylinder with a spiral protrusion, which is used in conjunction with the worm wheel. The shape of the worm wheel is similar to that of a disc gear. The tooth grooves of the gear are surrounded by the spiral protrusions of the worm. The contact surface between the worm and the worm wheel forms a spiral friction transmission surface, which drives the worm wheel to rotate through the rotation of the worm to achieve the purpose of deceleration. Durability means that the reducer has a long service life and high reliability, and can operate continuously and stably in various working environments without prone to failure or damage.

[0003] In order to prevent workers from getting hurt when using the worm gear reducer, a protective plate is usually installed on the side of the worm gear reducer where the connecting shaft is not set. The protective plate improves the safety of workers during operation. At the same time, the protective plate can also prevent dust and debris from entering the inside of the worm gear reducer, keep the inside of the worm gear reducer clean, and prevent the worm gear reducer from malfunctioning due to the entry of foreign matter. However, when regularly inspecting and maintaining the worm gear reducer, it is necessary to remove the protective plate set on one side of the worm gear reducer to facilitate the inspection of the inside of the worm gear reducer. Since the protective plate set on one side of the worm gear reducer is generally installed by multiple bolts, when inspecting and maintaining it, it is necessary to remove multiple bolts in turn before removing the protective plate. Such operation is extremely cumbersome, which increases the operating time of the workers and reduces the work efficiency of the workers.

[0004] Therefore, it is necessary to provide a new durable worm gear reducer to solve the above technical problems. Utility Model Content

Figure 2 .

[0027] In the specific implementation process, Figure 1-Figure 8 As shown, the durable worm gear reducer comprises a worm gear reducer body, a dustproof plate 1 for protecting the interior is provided on one side of the worm gear reducer body, and the dustproof plate 1 is connected to one side of the worm gear reducer body through a plurality of snap-fit ​​structures, the snap-fit ​​structure comprises a limit rod 2 and a plurality of snap-fit ​​blocks 3, one end of the limit rod 2 is fixedly connected to one side of the dustproof plate 1, both sides of the limit rod 2 are provided with fixing grooves 4 matching the snap-fit ​​blocks 3, a plurality of snap-fit ​​blocks 3 are respectively connected to the inner sides of the fixing grooves 4 through elastic members, a plurality of T-slots 5 for the limit rod 2 to move are provided on one side of the worm gear reducer body, and reset members are provided at both ends of the T-slots 5, and the ends of the plurality of snap-fit ​​blocks 3 away from the fixing grooves 4 are all inclined;

[0028] The elastic member is a spring 6, one end of which is fixedly connected to one end of the engaging block 3, and the other end of which is fixedly connected to the inner side of the fixing groove 4. The reset member includes a reset plate 7, which is located inside the T-shaped groove 5, and the reset plate 7 is connected to one end inside the T-shaped groove 5 through a spring 2 8. A connecting rod 9 is fixedly provided on the top of the reset plate 7, and a plurality of slide grooves 10 for sliding the connecting rod 9 are provided on the top of the worm gear reducer body, and a pull rod 11 is provided on the top of the connecting rod 9, and the pull rod 11 is concavely arranged;

[0029] A plurality of heat dissipation slots 12 for enhancing the air circulation inside the worm gear reducer body are provided on one side of the dustproof plate 1, and a plurality of dustproof nets 13 for preventing dust from entering the worm gear reducer body are provided inside the heat dissipation slots 12, a plurality of limit blocks 14 are provided at the bottom of the dustproof plate 1, and a plurality of limit slots 15 matching the limit blocks 14 are provided on one side of the worm gear reducer body;

[0030] The worm gear reducer body includes a housing 16, a connecting shaft 17 and a connecting shaft 2 18, wherein a worm 19 and a worm wheel 20 are arranged inside the housing 16, the outer ends of the connecting shaft 17 and the connecting shaft 2 18 are both located outside the housing 16, the inner ends of the connecting shaft 17 and the connecting shaft 2 18 respectively penetrate the outside of the housing 16, and are fixedly connected to one end of the worm 19 and the worm wheel 20 respectively, wherein the connecting shaft 17 and the connecting shaft 2 18 are respectively connected to other equipment through the outer ends, and a friction transmission surface is formed by the tooth surface contact between the worm 19 and the worm wheel 20, due to the spiral shape of the worm 19 and the tooth groove design of the worm wheel 20, when the worm 19 rotates, it will drive the worm wheel 20 to rotate through friction, so that the worm wheel 20 can rotate at a lower speed, thereby achieving a deceleration effect, and at the same time, the contact area between the worm wheel 20 and the worm 19 is large, with good transmission effect and load capacity, and can operate stably under high-load working conditions, thereby ensuring the durability of the worm gear reducer body under long-term and heavy-load working conditions.

[0031] The working principle provided by the utility model is as follows: when it is necessary to inspect or maintain the inside of the worm gear reducer body, pull the pull rod 11, and the pull rod 11 drives the connecting rod 9 to slide inside the slide groove 10 opened on the top of the worm gear reducer body, and when the connecting rod 9 slides, it drives the reset plate 7 to move inside the T-slot 5, and when the reset plate 7 moves inside the T-slot 5, it pushes the clamping block 3 to move inside the fixed groove 4, so that the outer side of the clamping block 3 is no longer in contact with the inner side of the T-slot 5, and the clamping state between the clamping block 3 and the T-slot 5 is released, and the dustproof plate 1 is pulled to make the limit block 14 at the bottom of the dustproof plate 1 disengage from the limit groove 15 opened in the worm gear reducer body, and the dustproof plate 1 is disassembled;

[0032] At the same time, when pulling the pull rod 11, because the pull rod 11 is concave, it can fit the contour of the palm more naturally when holding, reducing the gap between the palm and the pull rod 114, making the grip more fitting and comfortable. At the same time, the concave setting can form a natural gripping space, making it easier to put the palm on the pull rod 114 firmly, and providing better control.

[0033] The air circulation inside the worm gear reducer body is enhanced by a plurality of heat dissipation grooves 12 arranged on one side of the dustproof plate 1, thereby ensuring the normal use of the worm gear reducer body, and the dustproof net 13 arranged inside the heat dissipation groove 12 can effectively prevent external dust and fine particles from entering the inside of the worm gear reducer body through the heat dissipation groove 12, thereby improving the service life of the worm gear reducer body;

[0034] When the dustproof plate 1 needs to be installed, the limiting rod 2 provided on one side of the dustproof plate 1 is inserted into the T-slot 5 provided on one side of the worm gear reducer body. Because one end of the locking block 3 is inclined, when the inclined surface of the locking block 3 contacts the inner side of the T-slot 5, the inclined surface of the locking block 3 will slide along the inner side of the T-slot 5, so that the locking block 3 is contracted toward the inside of the fixed groove 4, and when the locking block 3 is contracted, the spring 1 6 is squeezed, and when the locking block 3 moves to the inside of the T-slot 5, under the elastic action of the spring 1 6, the locking block 3 will be driven to move toward the outside of the fixed groove 4, so that the outer side of the locking block 3 is respectively fitted with the inner side of the T-slot 5 and the side of the reset plate 7 away from the spring 2 8, and the stability of the dustproof plate 1 is guaranteed by the mutual cooperation between the locking block 3 and the T-slot 5.
