Description

TECHNICAL FIELD

[0001] The utility model relates to servo motor equipment (encoder equipment for electronic jacquard machine) technical field, especially electronic jacquard machine encoder gear assembly. BACKGROUND

[0002] With the continuous improvement of the speed of jacquard weaving, the further deepening of the national energy saving and consumption reducing policy, the main driving mode of electronic jacquard machine has faced the urgent demand of technological innovation, and the independent driving technology mode of servo motor for jacquard machine will be a kind of technical development trend of jacquard machine industry.

[0003] The traditional jacquard machine realizes synchronous work through the coupling, transmission shaft and reduction box and loom, wherein the servo motor is an important part of the jacquard machine, and the servo motor independently drives the jacquard machine to realize synchronous work with the loom through the gear driven electronic encoder.

[0004] However, the integrally formed nylon gear is affected by environmental factors, and the integrally formed nylon gear is not heat resistant. When the motor is running, the integrally formed nylon gear is heated and expanded, so that the screw and the thread are easy to loosen, causing the gear to fall off, so that the encoder cannot capture the signal, affecting the use of the whole machine. In addition, since the encoder is a measuring instrument that receives vibration and impact, the encoder gear is required to have high bearing capacity and withstand high impact and vibration in structure, so the fixing mode between the integrally formed nylon gear and the encoder is extremely important. Therefore, in view of the deficiencies of the encoder gear assembly in heat resistance and connection mode, an electronic jacquard machine encoder gear assembly is invented. SUMMARY

[0005] The utility model discloses a kind of electronic jacquard machine encoder gear assemblies to overcome the deficiencies of the above prior art, and provide a kind of electronic jacquard machine encoder gear assembly.

[0006] To achieve the above object, the utility model adopts the following technical scheme:

[0008] Preferably, the encoder gear seat is provided with a bolt hole corresponding to the bolt.

[0009] Preferably, the encoder gear is provided with a tooth groove and a boss, the boss is located at the middle position of the tooth groove, and the boss is integrally formed with the encoder gear.

[0010] Preferably, three bolts are equidistantly arranged on the boss.

[0011] Preferably, the middle of the encoder gear seat is provided with a main shaft hole, the screw extends to the main shaft hole, and chamfers are formed on both sides of the main shaft hole.

[0012] Preferably, chamfers are formed on both sides of the encoder gear seat.

[0013] The beneficial effects of the utility model are as follows:

[0014] 1. By arranging a threaded hole on the encoder gear seat, the screw is positioned through the threaded hole and the encoder main shaft, so that the encoder and the encoder gear seat are more closely connected, and the problem of easy loosening of the thread is solved; by arranging the encoder gear and the encoder gear seat in a split state, the encoder gear seat is made of aluminum alloy material, the encoder gear seat made of aluminum alloy material is more resistant to high temperature, and will not be deformed and expanded due to the heat generated during the operation of the encoder, thereby solving the problem that the integrally formed nylon gear is expanded due to heat, the thread is easily loosened, the gear is detached, and the encoder cannot capture signals.

[0015] 2. The encoder gear and the encoder gear seat are detachably connected by arranging the bolt, the pre-tightening force generated by tightening the bolt makes the encoder gear and the encoder gear seat closely adhere and fix, so that the fastening effect is improved; the boss arranged on the encoder gear can increase the bearing capacity of the encoder gear; the tooth groove arranged on the encoder gear reduces the weight of the encoder gear and reduces the moment of inertia of the encoder gear, thereby reducing the noise and vibration generated during the operation of the encoder gear.

[0022] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.

[0024] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0026] like Figures 1-5 As shown, an encoder gear assembly for an electronic jacquard machine includes an encoder gear 1, on which a tooth groove 11 and a boss 12 are provided. The boss 12 is located in the middle of the tooth groove 11. Providing the tooth groove 11 on the encoder gear 1 not only reduces the weight of the encoder gear 1, but also reduces the rotational inertia of the encoder gear 1, thereby reducing the noise and vibration during the operation of the encoder gear 1. When the encoder gear 1 is subjected to vibration during the operation of the encoder, the boss 12 can increase the load-bearing capacity of the encoder gear 1. In addition, the encoder gear 1 and the encoder main gear contact and cooperate with each other to transmit steering force and motion, thereby driving the operation of the encoder, and realizing the synchronous operation of the servo motor and the loom through the encoder.

[0027] Further, one side of the encoder gear 1 is provided with an encoder gear seat 2, which is detachably connected with the encoder gear 1 through bolts 3 on the other side of the encoder gear 1. Both ends of the encoder gear seat 2 are provided with bolt holes 21 corresponding to the positions of the bolts 3. The threaded portions of the bolts 3 pass through the bolt holes 21 of the encoder gear 1 and the encoder gear seat 2, and the pre-tightening force generated by tightening the bolts makes the encoder gear 1 and the encoder gear seat 2 tightly fit and fixed. The bolts 3 are equally spaced in three groups, and each group of bolts 3 is stressed, so that the encoder reduces shaking and increases stability when running. In addition, the head of the bolt 3 is hexagonal in shape, which not only improves the fastening effect of the encoder gear 1 and the encoder gear seat 2, but also provides a larger contact area, making the bolt 3 more stable under stress, so it is not easy to loosen.

[0028] Reference Figure 1 , Figure 5 As shown in the figure, two threaded holes 22 are arranged on the encoder gear seat 2, which are arranged at 90°. A main shaft hole 23 is arranged in the middle of the encoder gear seat 2. The screws pass through the threaded holes 22 and the encoder main shaft passing through the main shaft hole 23 to position. Not only can the encoder and the encoder gear seat 2 be more tightly connected, but also solve the problem of easy loosening of the thread, but also protect the main shaft of the encoder, so that the encoder can withstand higher impact and vibration.

[0029] Further, the encoder gear seat 2 is made of aluminum alloy material. Compared with nylon material, aluminum alloy material is more resistant to high temperature. The heat resistance temperature of aluminum alloy material is 150℃-450℃, so the encoder gear seat 2 will not deform and expand due to the heat generated during the operation of the encoder, so that the thread loosening causes the encoder gear 1 to fall off, so that the encoder cannot capture the signal. That is, the use of aluminum alloy material for the encoder gear seat 2 makes the connection between the encoder gear seat 2 and the encoder 5 not easy to loosen during the operation of the encoder. In addition, since the encoder gear 1 and the encoder gear seat 2 are in a split state, the encoder gear seat 2 can be disassembled and replaced according to different models of the encoder 5, thereby reducing the maintenance cost.

[0030] Reference Figure 1 , Figure 5 As shown in the figure, chamfers are arranged on both sides of the encoder gear seat 2, and chamfers are also arranged on both sides of the main shaft hole 23 at the middle position of the encoder gear seat 2, so that the transmission between the encoder gear 1 and the corresponding synchronous gear is more accurate, the leakage phenomenon is reduced, and the encoder gear 1 can be protected from damage. In addition, the small protrusions at the chamfers can disperse the impact force, thereby reducing the mutual interference between the gears and reducing the noise and vibration during the operation of the machine body.

[0031] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
