Abstract
The utility model relates to a transmission shaft structure of a polishing machine, which comprises a hand-held main pipe, a polishing head, a transmission shaft and a drive motor, wherein the drive motor is arranged on the rear end of the hand-held main pipe; the transmission shaft comprises a hard transmission shaft arranged in the hand-held main pipe and a flexible transmission shaft arranged outside the hand-held main pipe; one end of the flexible transmission shaft is connected with the polishing head in a transmission way and the other end is connected with the front end of the hard transmission shaft in a transmission way; and the rear end of the hard transmission shaft is connected with the output shaft of the drive motor in a transmission way. According to the transmission shaft structure disclosed by the utility model, the combined transmission by using the hard transmission shaft and the flexible transmission shaft is adopted, and only a small section of flexible transmission shaft is used, is convenient for routine maintenance and oil charge and can be replaced conveniently after being damaged; the hard transmission shaft is longer than the flexible transmission shaft in service life and difficult to damage, thus the maintenance cost can be reduced; and the hard transmission shaft is better than the flexible transmission shaft in transmission effect, thus the transmission reliability can be ensured.
Description
Technical field:
The utility model relates to the transmission shaft structure of a kind of sander that wall, ceiling etc. is polished and polishes, particularly a kind of sander.
Background technology:
The tradition sander all is to adopt a flexible axle to transmit the outputting power of drive motors, drives that grinding head rotates and the work of polishing, thereby has following deficiency: the one, and flexible axle often twists off, and service life is short; The 2nd, after occurring damaging, necessary whole replacing not only change inconvenience, and maintenance cost is high; The 3rd, the transmission effect is not good enough, and transmission is unreliable.
The utility model content:
Goal of the invention of the present utility model is to overcome the deficiency of above-mentioned prior art, and a kind of long service life is provided, and is easy to maintenance, cost is low, and the transmission shaft structure of the sander of reliable transmission.
Goal of the invention of the present utility model is achieved through the following technical solutions:
A kind of transmission shaft structure of sander, comprise hand-held supervisor, grinding head, power transmission shaft and drive motors, described drive motors is arranged on hand-held supervisor's rear end, described power transmission shaft comprises being arranged on the hard axle of transmission in the hand-held supervisor and being arranged on hands the outer driving snake of supervisor, described driving snake one end and grinding head are in transmission connection, the front end of the other end and the hard axle of transmission is in transmission connection, and the rear end of the hard axle of described transmission and the output shaft of drive motors are in transmission connection.
The hard axle of described transmission can adopt the two-period form segmental structure, it is comprised of the hard axle of A transmission and the hard axle of B transmission, wherein, be connected by the A shaft coupling transmission between the output shaft of the hard axle of A transmission and drive motors, connect by the B shaft coupling transmission between A, the hard axle of B transmission, be connected by the C shaft coupling transmission between the hard axle of B transmission and the driving snake.
Described A shaft coupling one end is threaded with the output shaft of drive motors, the other end is connected with the hard axle movable teeth cover of A transmission, described B shaft coupling one end is connected with the hard male thread of A transmission, the other end is connected with the hard axle movable teeth cover of B transmission, described C shaft coupling one end is connected with the hard male thread of B transmission, and the other end adopts flat square structure to be connected with driving snake.
The hard axle of described transmission also can adopt multisection type segmental structure more than two sections.
The hard axle of described transmission can also adopt monolithic construction.
The hard axle of described transmission is arranged on hand-held supervisor's center.
The beneficial effects of the utility model are:
Adopt hard axle to be combined transmission with flexible axle, flexible axle only has a bit of, be convenient to maintain at ordinary times refuel and gone bad after change.And hard axle can not damage easily than the long service life of flexible axle, therefore also can reduce maintenance cost.Moreover the transmission effect of hard axle is better than flexible axle, thereby can also guarantee the reliability of transmission.
Description of drawings:
Introduce in detail the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation of the utility model sander.
The specific embodiment:
Referring to Fig. 1, as a kind of embodiment of the present utility model, the transmission shaft structure of this sander comprises hand-held supervisor 1, grinding head 2, power transmission shaft and drive motors 3.Drive motors 3 is arranged on hand-held supervisor's 1 rear end, power transmission shaft comprises being arranged on the hard axle 4 of hand-held supervisor 1 interior RC transmission and being arranged on to hand is responsible for 1 outer driving snake 5, driving snake 5 one ends and grinding head 2 are in transmission connection, the front end of the hard axle 4 of the other end and transmission is in transmission connection, and the rear end of the hard axle 4 of transmission and the output shaft 31 of drive motors 3 are in transmission connection.
The hard axle 4 of transmission can adopt the two-period form segmental structure, it is comprised of the hard axle 41 of A transmission and the hard axle 42 of B transmission, wherein, be in transmission connection by A shaft coupling 6 between the output shaft 31 of the hard axle 41 of A transmission and drive motors 3, be in transmission connection by B shaft coupling 7 between A, the hard axle 41 of B transmission, 42, be in transmission connection by C shaft coupling 8 between the hard axle 42 of B transmission and the driving snake 5.
A shaft coupling 6 one ends are threaded with the output shaft 31 of drive motors 3, the hard axle 41 movable teeths cover of the other end and A transmission is connected (i.e. being connected by teeth groove and double wedge, so both can realize transmission, again can ease of assembly and dismounting), B shaft coupling 7 one ends are threaded with the hard axle 41 of A transmission, the other end is connected with the hard axle 42 movable teeths cover of B transmission, and C shaft coupling 8 one ends are threaded with the hard axle 42 of B transmission, and the other end adopts flat square structure to be connected with driving snake 5.
