Description
Technical Field
The utility model relates to a transmission, especially a transmission that can offset the radial force that the main shaft bore.
Background
In mechanical devices, most spindles are connected to a motor, and torque is transmitted to the spindle through the motor to drive the spindle to rotate.
Disclosure of Invention
The utility model relates to a solve the above-mentioned not enough that prior art exists, provide a simple structure, design benefit, rationally distributed can effectively offset the radial force that the main shaft bore to prevent this kind of radial force from causing the transmission of influence to the motor.
The technical solution of the utility model is that: a main shaft radial force unloading transmission device is characterized in that: the transmission include through the cover 1 support frame 3 of connecting on main shaft 2 that rises, shown support frame 3 passes through connecting pin 4 and 5 fixed connection of synchronous pulley, synchronous pulley 5 pass through bearing 6 and auxiliary stand 7 and rotate and be connected, auxiliary stand 7 center department set up the round hole that the diameter is greater than main shaft 2 diameter, auxiliary stand 7 still passes through connecting bolt 8 and casing 9 fixed connection simultaneously, the winding has hold-in range 10 on the synchronous pulley 5, the other end of hold-in range 10 then the winding is on passive synchronous pulley, the one end of main shaft 2 links to each other with driving motor's output.
Compared with the prior art, the utility model, have following advantage:
this kind of structural style's transmission to the problem that traditional transmission can transmit the radial force that bears for the main shaft at the course of the work, and then influence motor work and life, designs a special structure, and it can transmit the radial force for auxiliary stand through the bearing, finally transmits to the casing on to play the purpose of protection main shaft and motor. The motor protection device can effectively protect a main shaft and a motor in a transmission device, can prevent the motor from breaking down in the working process, prolongs the service life of the motor as far as possible, and saves a large amount of later maintenance, repair and motor replacement costs for enterprises. And the manufacturing process is simple, the manufacturing cost is low, so that the novel LED lamp has multiple advantages, is particularly suitable for popularization and application in the field, and has a very wide market prospect.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Detailed Description
The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1: the utility model provides a main shaft radial force off-load transmission, it includes and connects support frame 3 on main shaft 2 through the cover 1 that rises, shown support frame 3 is through connecting pin 4 and 5 fixed connection of synchronous pulley, synchronous pulley 5 rotate with auxiliary stand 7 through bearing 6 and be connected, auxiliary stand 7 center department set up the round hole that the diameter is greater than main shaft 2 diameter, auxiliary stand 7 still passes through connecting bolt 8 and casing 9 fixed connection simultaneously, the winding has hold-in range 10 on the synchronous pulley 5, the other end of hold-in range 10 then the winding is on passive synchronous pulley, the one end of main shaft 2 links to each other with driving motor's output.
The utility model discloses can offset transmission of radial force that the main shaft bore's working process as follows: the driving motor is started, the driving motor directly drives the main shaft 2 to rotate, the supporting frame 3 connected with the main shaft 2 through the expansion sleeve 1 and the synchronous pulley 5 on the supporting frame rotate along with the main shaft, and then the driven synchronous pulley is driven to rotate through the synchronous belt 10, namely the device is essentially a belt pulley transmission pair and transmits the torque of the driving motor to the driven synchronous pulley;
in the above process, since the synchronous pulley 5 is connected to the auxiliary support 7 through the bearing 6, if the synchronous pulley 5 bears a radial force, the radial force is also transmitted to the auxiliary support 7 through the bearing 6, and the auxiliary support 7 is not in direct contact with the main shaft 2 (the main shaft 2 passes through a circular hole formed in the center of the auxiliary support 7), so that the radial force is not directly transmitted to the main shaft 2 but transmitted to the housing 9 through the auxiliary support 7, that is, all the radial force is borne by the housing 9 of the mechanism, thereby achieving the purpose of protecting the main shaft 2 and the driving motor connected with the main shaft.
