Abstract
Provided is a low-speed transmission device of a mill. A motor direct-connection type speed reducer is used as a prime motor of the low-speed transmission device, an overrun clutch is mounted at the low-speed end of the speed reducer, a star wheel of the overrun clutch is sleeved on the low-speed end of the speed reducer, an outer ring of the overrun clutch is connected with a coupling half mounted on a high-speed shaft of a main speed reducer of the mill through a rod pin, and a main motor of the mill is connected with the other side of the high-speed shaft of the main speed reducer through a coupler. The low-speed transmission device of the mill is simple in structure, high in reliability, small in size and convenient to use. When the main motor is started, the clutch needs not to be separated manually, and a starting torque of the main motor can be greatly reduced.
Description
Technical field
The utility model relates to a kind of mechanical driving device, relates in particular to a kind of at a slow speed transmission device of grinding machine.
Background technology
The at a slow speed transmission device of present known grinding machine is that motor drives planetary reducer by shaft coupling, planetary reducer low speed end is equipped with claw-type clutch, realizes the at a slow speed transmission of grinding machine by the clutch of manually pulling claw-type clutch and grinding machine pinion shaft.The defective of this form is that complex structure, volume are large, price is high, use is inconvenient, poor reliability, and this form can only be used for the maintenance of grinding machine, must treat when grinding machine master machine operation starts manually claw-type clutch to be thrown off and could be started when grinding machine remains static, otherwise damaging will appear in transmission device at a slow speed.The disclosed slow transmission device for ball grinding machine of CN201120361697.7 has only solved that the transmission device volume is large at a slow speed, the defective that price is high, equally only can be used for the grinding machine maintenance, owing to still having adopted claw-type clutch, claw-type clutch must be thrown off when grinding machine master machine operation starts.
The utility model content
The purpose of this utility model is to provide at a slow speed transmission device of a kind of novel grinding machine, overcomes conventional mill transmission structures is complicated at a slow speed, volume large, poor reliability, awkward shortcoming.
A kind of grinding machine is transmission device at a slow speed, it is characterized in that: adopt at a slow speed prime mover of transmission device of motor direct-connection type reductor conduct, the low speed end of reductor is equipped with freewheel clutch, the star-wheel of freewheel clutch is enclosed within on the low speed end of reductor, the outer shroud of freewheel clutch is connected with half a coupler on being installed in grinding machine main reducing gear high speed shaft by the rod pin, and the main motor of grinding machine then is connected by the opposite side of shaft coupling with the main reducing gear high speed shaft.
Because transmission device is to be connected with grinding machine main reducing gear high speed shaft at a slow speed, so the speed ratio of reductor can reduce widely than traditional slow transmission device, thereby reduces the at a slow speed volume of transmission device.And owing to having adopted freewheel clutch, when grinding machine is worked, can start first at a slow speed transmission device, the star-wheel of freewheel clutch drives the outer shroud rotation, thereby drives at a slow speed transmission of grinding machine.This moment is with at a slow speed driving motor outage of grinding machine, main motor is started working, because main motor speed is greater than the speed reducer output shaft rotating speed of transmission device at a slow speed, therefore the outer shroud rotating speed of freewheel clutch is greater than star wheel rotate speed, clutch surmounts, transmission device and grinding machine main reducing gear are thrown off automatically at a slow speed, and grinding machine is started working.Since grinding machine be under certain rotating speed by main motor-driven, under inactive state, start, the starting torque of main motor can reduce widely, when having reduced electric motor starting to the impact of electrical network.
Transmission structures is simple at a slow speed, reliability is high for grinding machine of the present utility model, volume is little, easy to use, need not declutch by changable during main electric motor starting, and is easy to use, and can greatly reduce grinding machine master electric motor starting moment, when having reduced electric motor starting to the impact of electrical network.
Description of drawings
Fig. 1 is at a slow speed transmission structures schematic diagram of grinding machine of the present utility model;
1. motor, 2. reductor, the 3. star-wheel of freewheel clutch, the 4. outer shroud of freewheel clutch, 5. rod pin, 6. half a coupler, the 7. high speed shaft of main reducing gear.
The specific embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:
Motor 1 and reductor 2 are for directly to connect in the accompanying drawings, and the star-wheel 3 of freewheel clutch is installed on the slow-speed shaft of reductor 2, and the outer shroud 4 of freewheel clutch is connected by rod pin 5 with half a coupler 6 on the high speed shaft 7 that is installed in main reducing gear.
Grinding machine is transmission device when work at a slow speed, thereby motor 1 drives star-wheel 3 rotations that reductor 2 drives freewheel clutch, because the former inactive state that is in of grinding machine, the outer shroud 4 of freewheel clutch is static, therefore freewheel clutch combination, thus the outer shroud 4 that drives freewheel clutch rotates, and the outer shroud 4 of freewheel clutch drives half a coupler 6 by rod pin 5 and rotates, the main reducing gear of grinding machine is started working, the grinding machine slow rotation.
When grinding machine master motor need to be started working, as long as start first at a slow speed transmission device, after the grinding machine slow start is stable, grinding machine master motor is started working, and cuts off simultaneously the at a slow speed power supply of transmission device motor since the velocity ratio of grinding machine master motor the low speed end of transmission device reductor is high at a slow speed, therefore the outer shroud speed of freewheel clutch is higher than star-wheel speed, freewheel clutch surmounts, and grinding machine is able to smooth startup, and starting torque reduces widely.
If adopt the pattern of motor, shaft coupling, reductor to replace motor 1 and reductor 2 direct coupled modes, connecting replacement rod pin 5 with bolt also has same effect.
Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model, can not assert that implementation of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field; make without departing from the concept of the premise utility some alternative or obvious modification that are equal to; and performance or purposes are identical, then should be considered as belonging to the protection domain that claims that the utility model submits to are determined.
