New description: [New technical field] ‘In particular, it relates to a transmission structure assembly of a linear scripting system and a linear actuator. [Prior Art] Referring to the fourth and fifth figures, the conventional linear actuator transmission Lu, the structural assembly (1) is a coupling-linear actuator (2)-motor (7), the transmission structure assembly (1) Driven by the motor (3); the transmission structure assembly (1) comprises two housings (4), a screw (5), a worm wheel (6), two bearings (7) and two pins (8) and an upper cover (9). The screw (7) and the worm wheel (6) are fixedly connected in series via the pins (8), thereby achieving the purpose of fixing the screw (5) and the worm wheel (6). However, it is known that the pins (8) - after being installed, cannot be dismantled. In other words, when the linear actuator (7) needs to be repaired, it is quite difficult, and • often requires destructive disassembly. The linear actuator (2) is inspected; further, the conventional linear actuating jaw is only supported by the upper cover (9), and the components are not _real' A gap is generated during the lowering movement, which causes errors in the screw stroke and affects product quality. In summary, the transmission structure assembly of the conventional linear actuator has the above-mentioned defects and needs to be improved. [New content] The main purpose of this creation is to provide a linear actuator actuator structure, which has the functions of easy disassembly and assembly, and can greatly improve the precision of the product. In order to achieve the above object, the present invention provides a linear actuator transmission structure assembly that is coupled to and driven by a motor of a linear actuator. The 5H transmission structure assembly includes: a housing, the interior Having a long straight passage, a screw is disposed in the casing and located in the passage; a wheel is internally screwed to the screw and externally coupled to the motor; and two bearings are sleeved at the end of the worm wheel and respectively Located on opposite sides of the worm wheel, each of the two opposite side knives of the bearing is attached to the 埚 埚 wheel and the casing; a limiting member is used to confuse the screw with the screw, and the stern is stabilized with the mast a locking firmware for passing through the limiting member and combining with the screw. Accordingly, the transmission structure assembly of the linear actuator provided by the present invention can easily provide the functions of disassembly and assembly by the above structure, so as to overcome the lack of easy disassembly of the conventional person; It is specially designed to facilitate the maintenance work and the compactness of the components after the group. The following is a detailed description of the structure, features, and functions of the present invention. The following is a description of the preferred embodiment and the accompanying drawings. The second figure is an exploded view of an element of a preferred embodiment of the present invention. The second figure is a schematic cross-sectional view of a preferred embodiment of the present invention. Referring to the first to third figures, the transmission actuator assembly (1〇) of the linear actuator provided by the present invention is coupled to a motor M381007 (101) of one linear actuator (1〇〇) and Driven by the motor (101), the transmission structure assembly (10) comprises: a housing (20), a screw (30), a worm wheel (40), two bearings (5 〇 a) (50B), a The main components such as the locker (60), a limiting member (66) and an upper cover (70). The housing (20) has a long straight passage (22) therein; the housing (20) is not a technical feature of the present invention, and is merely illustrative and not limiting. The screw (30) is disposed in the casing (20) and is located in the passage (22). The front end of the screw (30) is disposed as a locking zone (301), which is a groove in this embodiment. It is not limited to this and a screw hole (3〇2) is provided in the middle of the cassette area (3〇1). The inside of the wheel (40) is screwed to the screw (3〇), and the outer tooth region (401) of the middle portion of the worm wheel (4) is coupled to and driven by the motor (101), and the worm wheel (40) A first joint portion (42) is provided in the periphery of the inner hole of the top portion, which is an inner tooth region in this embodiment, but is not limited thereto. . The two bearings (50A) (50B) are disposed in the channel (22) and sleeved at the ends of the wheel (40) and respectively located on opposite sides of the wheel (4〇).两A)(5〇B) The opposite sides are respectively attached to the worm wheel (4〇) and the casing (10). The firmware (60) has a screw, a tooth portion (62) and a head portion (four), and the screw portion (62) is locked in the screw hole (3〇2) of the screw (30) and is the same as the screw rod (10) Axial. The limiting member (66) is provided with a latching portion (41) which is fitted with an outer shape at a position corresponding to the cartridge region (10) of the screw (10), and a second joint 邛 (661) is further disposed on the outer periphery thereof. For example, an outer tooth zone can be engaged with the worm wheel (the first joint portion (42). The cover () is locked to the outer end 5 of the casing (20) by a plurality of screws (80). For covering the locking member (60) and the limiting member (66) and pressing the outer edge of the bearing (50A), the external pressing force of the upper cover (70) will make the housing (20) The screw (30), the wheel (40) and the bearing (50A) (5〇B) greatly reduce the assembly gap, so as to effectively reduce the mechanical error of the axial displacement of the screw (3〇). When the bearing (50B), the worm wheel (40), the bearing (50A) are sequentially sleeved on the screw (30) and accommodated in the passage (22) inside the casing (2) Wherein the latching portion (41) of the limiting member (66) is engaged with the latching region (301) of the screw (30), and then the second engaging portion (661) is correspondingly engaged with the latching portion (661) In the first joint (42) of the worm wheel (4〇), the fastener (60) is finally put into the limit member (66). And screwing with the screw hole (302) of the screw (3), and completing the stable fixing position of the above two bearings (5〇A) (5〇B). Finally, the upper cover (70) is screwed by several screws (8〇) After being combined with the casing (2〇), the above-mentioned components are accommodated in the casing (2〇), and at this moment, the gap between the components will not be generated, and the precision of the linear actuator is greatly improved. Through the above structure, when the motor (1〇1) drives the worm wheel (4〇) to rotate, the side of the worm wheel (40) is blocked by the casing (2〇), and the other side receives the lock (60) The lock 掣 'Therefore, the screw (3 〇) advances forward or backward in the long axial direction, and does not produce any _ and has a delay error. Structurally, the transmission structure assembly (10) Replacing the conventional locks with the lock (6〇), which can provide disassembly, assembly and maintenance of the components; furthermore, it can secure the above two bearings (50A) (50B), The assembly gap will be generated, and the precision of the linear actuator will be greatly improved. 6 M381007 In summary, the constituent elements disclosed in the foregoing embodiments are merely examples.
