Description
Technical Field
[0001] This utility model belongs to the technical field of gear reducers, and in particular relates to a gear reducer for transmission equipment. Background Technology
[0002] In various transmission equipment such as logistics transportation and production line conveyors, gear reducers are core transmission components. By reducing speed and increasing torque, they achieve a precise match between the power of the drive motor and the operational needs of the transmission mechanism, ensuring the stable and efficient operation of the transmission equipment. Currently, the connection between gear reducers and drive motors in transmission equipment is mostly achieved by directly locking them to fixed brackets. This installation structure has gradually revealed many defects in practical applications, making it difficult to meet the needs of use under complex working conditions.
[0003] First, installing the drive motor requires a crane, which can cause swaying, making installation inconvenient and significantly reducing efficiency. Repeated adjustments may also damage the connection surfaces. Second, the existing connection structure lacks stability. Some installation structures are connected to the motor bottom only by a single bracket. Vibration during motor operation can loosen the connecting bolts, leading to motor displacement, affecting transmission accuracy, and in severe cases, causing abnormal noise, accelerating gear wear, and shortening the equipment's lifespan.
[0004] To address these issues, we provide a transmission device gear reducer. Utility Model Content
[0005] The purpose of this utility model is to provide a gear reducer for transmission equipment. By cooperating with the gear reducer body, drive motor and adjustment support components, it solves the problems of inconvenient installation and poor connection stability between the gear reducer and the motor in the prior art.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.
[0007] This utility model relates to a gear reducer for transmission equipment, comprising a gear reducer body, an input end of which is fixedly connected to a drive motor by bolts, and an adjustment support assembly fixedly connected to the bottom of the drive motor by bolts. The adjustment support assembly includes a lead screw fixedly connected to the bottom of one side of the gear reducer body by bearings, a movable seat being threadedly connected to the surface of the lead screw, a placement seat being fixedly connected to the top of the movable seat, the drive motor being placed on the top of the placement seat, connecting blocks being fixedly connected to both the front and back of the placement seat, a connecting plate being fixedly connected to the surface of the connecting blocks by bolts, the other side of the connecting plate being fixedly connected to the drive motor, and an internal hexagonal groove being provided at the end of the lead screw away from the bearing.
[0008] The present invention is further configured such that the inner cavity of the movable seat is provided with a threaded hole, and the threaded hole is threadedly connected to the lead screw.
[0009] The present invention is further configured such that limit holes are provided at both the front and rear ends of the inner cavity of the movable seat, and limit rods are slidably connected to the inner cavities of the limit holes, with one end of the limit rods being fixedly connected to the gear reducer body.
[0010] The present invention is further configured such that a positioning hole is provided on the top of the placement base, a positioning rod is inserted into the inner cavity of the positioning hole, and the top of the positioning rod is fixedly connected to the bottom of the drive motor.
[0011] The present invention is further provided that mounting holes are provided at all four corners of the bottom of the gear reducer body.
[0012] The present invention is further configured such that the inner cavity of the connecting block is provided with a screw hole, the surface of the connecting plate is provided with a through hole, and the inner cavities of the through hole and the screw hole are threadedly connected with bolts.
[0013] The present invention is further configured such that the placement base adopts an arc-shaped design.
[0014] The present invention is further provided that the top of both the gear reducer body and the drive motor are fixedly connected with hanging lugs.
[0015] The present invention has the following beneficial effects.
[0016] 1. The arc-shaped design of the placement base and the positioning rod of this utility model enable the motor to be initially placed without relying on a crane for continuous hoisting, reducing the difficulty of installation. The threaded transmission structure of the lead screw and the moving base, combined with the guiding constraint of the limit rod, allows for precise fine-tuning of the motor position and quick correction of coaxiality using an Allen wrench. This avoids the tedious operation of repeated disassembly and shim addition in traditional installation, greatly improving installation efficiency and reducing damage to the equipment connection surfaces caused by repeated adjustments.
[0017] 2. The arc-shaped mounting base of this utility model fits tightly against the bottom of the motor, increasing the support contact area and dispersing the vibration load during motor operation; the bidirectional bolt fixing of the connecting block and the connecting plate forms a circumferential constraint on the motor, which, together with the axial positioning of the positioning rod and the positioning hole, effectively limits the motor's movement space; the limiting rod prevents the moving base from shifting, further ensuring the stability of the motor position, reducing the risk of bolt loosening caused by motor vibration, avoiding the problems of decreased transmission accuracy, abnormal noise and gear wear caused by motor displacement, and significantly extending the service life of the equipment.

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0026] Please see Figures 1-5 This utility model relates to a gear reducer for transmission equipment, comprising a gear reducer body 1, a drive motor 2, and an adjustment support assembly 3, which work together to achieve power transmission and stable installation. In this embodiment, the housings of the gear reducer body 1 and the drive motor 2 are integrally cast from high-strength cast iron to ensure structural rigidity; the lead screw 31 in the adjustment support assembly 3 is made of high-strength alloy steel after quenching and tempering; the moving seat 32 and the placement seat 33 are injection molded from PA nylon reinforced with glass fiber; and the limiting rod 39, the positioning rod 311, and various bolts are all made of stainless steel, balancing strength and corrosion resistance.
[0027] The gear reducer body 1 is the core transmission carrier. Its input end is equipped with a connecting flange that is compatible with the output shaft of the drive motor 2. Mounting holes are opened at the four corners of the bottom to fix the body to the frame of the transmission equipment. The top of the body is fixedly connected with a hanging lug to facilitate the overall hoisting and transportation of the equipment.
[0028] The output shaft of the drive motor 2 is connected to the input end of the gear reducer body 1. A positioning rod 311 is welded to the bottom of the drive motor 2. The positioning rod 311 is precisely matched with the positioning hole 310 on the top of the placement seat 33 to achieve the initial positioning of the drive motor 2. The top of the drive motor 2 is also fixed with a hanging lug, which cooperates with the hanging lug of the reducer body to facilitate coordinated hoisting.
[0029] The adjustment support assembly 3 is the core adjustment structure. Its lead screw 31 is fixedly connected to the bottom of one side of the gear reducer body 1 through a deep groove ball bearing. The end of the lead screw 31 away from the bearing has an internal hexagonal groove 36, which is suitable for operation with an internal hexagonal wrench. The surface of the lead screw 31 is threadedly connected to a movable seat 32. The inner cavity of the movable seat 32 has a threaded hole 37 that matches the lead screw 31. At the same time, limit holes 38 are opened at both the front and rear ends. Limit rods 39 are slidably connected in the limit holes 38. One end of the limit rod 39 is welded and fixed to the gear reducer body 1, forming a guide constraint structure for the movable seat 32 to prevent it from deflecting as the lead screw 31 rotates.
[0030] The top of the movable base 32 is fixedly connected to the placement base 33 by bolts. The placement base 33 adopts an arc design, and its curvature is completely in contact with the bottom outer circle of the drive motor 2, which improves the contact area and support stability. The front and back of the placement base 33 are integrally formed with connecting blocks 34. The inner cavity of the connecting block 34 is provided with screw holes, and the surface of the connecting plate 35 is provided with corresponding through holes. Bolts pass through the through holes and are threadedly connected to the screw holes, so as to tightly fix the other side of the connecting plate 35 to the housing of the drive motor 2.
[0031] The working principle of this utility model is as follows: S1: During installation preparation, first use expansion bolts to fix the gear reducer body 1 to the preset mounting surface of the transmission equipment through the mounting holes at the bottom of the gear reducer body 1, ensuring that the body is installed firmly and without loosening. S2: The motor is lifted by the lug on the top of the drive motor 2 and slowly placed into the arc groove of the placement seat 33, so that the positioning rod 311 at the bottom of the motor is accurately inserted into the positioning hole 310 of the placement seat 33, thus completing the initial positioning of the motor and avoiding displacement during placement. S3: Attach the connecting plate 35 to the surface of the connecting block 34, and tighten it by passing bolts through the through holes and screw holes to achieve initial fixation of the motor and the mounting base 33; S4: Insert an Allen wrench into the Allen groove 36 of the lead screw 31 and rotate the lead screw 31 clockwise or counterclockwise. Under the action of the threaded transmission, the moving seat 32 moves linearly along the limit rod 39, thereby driving the drive motor 2 on the placement seat 33 to move synchronously, accurately adjusting the coaxiality of the motor and the input end of the reducer body until the coupling is connected smoothly without jamming. S5: After the coaxiality adjustment is completed, tighten the bolts between the connecting plate 35 and the connecting block 34, as well as the fixing bolts between the moving seat 32 and the placement seat 33, to complete the overall installation.

The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to the specific implementation methods described. The present specification selects and specifically describes these embodiments in order to better explain the principle and practical application of the present utility model, so that those skilled in the art can better understand and utilize the present utility model.
