Abstract
The utility model discloses a driving device for a rotary kiln. The driving device comprises a main motor (1) and a main speed reducer (2), the main speed reducer (2) is a double input shaft speed reducer; the main motor (1) is connected with one input shaft of the main speed reducer (2), an output shaft of the main speed reducer (2) is connected with a driving wheel (3) of the rotary kiln; the other input shaft of the main speed reducer (2) is connected with an auxiliary transmission (5) via a unidirectional overrunning shaft coupling (6). The driving system in the utility model can automatically perform switch of double drives, the auxiliary transmission is in standby and stationary, and is not driven by the main motor and the main speed reducer; two motors can rotate simultaneously without influencing each other; when neither of the two motors is driven, a backstop installed on the auxiliary transmission can prevent the rotary kiln from generating counter-current rotation, then the internal of the unidirectional overrunning shaft coupling is in a wedging state and transmits a reverse moment. No manual operation is needed, improving automation degree of system.
Description
Technical field
The utility model relates to a kind of drive unit, particularly relates to a kind of drive unit of rotary kiln, belongs to the drive technology field in the calcining petroleum coke production.
Background technology
Rotary kiln is a kind of Thermal Equipment of bulk material or pasty material being carried out heat treated.Except the main transmission of keeping the operate as normal running, also require rotary kiln to be equipped with a cover auxiliary drive generally speaking, use during in order to main transmission fault or kiln maintenance.Usually two power shafts are set on the speed end of rotary kiln main gear reducer, a motor that connects main transmission, another connects the output of accessory drive.Main motor and accessory drive motor adopt the power supply of different circuit respectively.
In order not allow phase mutual interference between main transmission and the accessory drive, prior art generally is at the position that rotary kiln main gear reducer high speed shaft is connected with accessory drive a manual clutch to be set, when main driving motor is worked this clutch separately, when the needs accessory drive is worked just by the combination of manually-operated clutch.The problem that this structure exists is that owing to need manually-operated, automaticity is low.
Summary of the invention
The purpose of this utility model is, a kind of drive unit of rotary kiln is provided.Improve the automaticity of rotary kiln drive unit.
The technical solution of the utility model: a kind of drive unit of rotary kiln, comprise main motor and main gear reducer, main gear reducer is the dual input shaft reductor; Main motor is connected with one of them power shaft of main gear reducer, and the output shaft of main gear reducer is connected with the rotary kiln driven wheel; Another power shaft of main gear reducer is connected with accessory drive through the mono-directional overrun shaft coupling.
In the drive unit of aforementioned rotary kiln, described mono-directional overrun shaft coupling comprises by freewheel clutch and yielding coupling and combining.
In the drive unit of aforementioned rotary kiln, described accessory drive is provided with two output shafts, and an output shaft is connected with the mono-directional overrun shaft coupling, and another is connected with holdback.
Compared with prior art, drive system of the present utility model can automatically be carried out two switchings that drive, and the accessory drive standby is static, is not subjected to the driving of main motor and main gear reducer; Two motors can rotate simultaneously and not influence each other; When two motors did not all drive, the holdback of adorning on the accessory drive can prevent rotary kiln generation backwards rotation, and at this moment the inside of mono-directional overrun shaft coupling is in the wedging state and transmits stall torque.Do not need manually-operated, improved the automaticity of system.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Being labeled as in the accompanying drawing: 1-master's motor, 2-main gear reducer, 3-rotary kiln driven wheel, 4-holdback, 5-accessory drive, 6-mono-directional overrun shaft coupling.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples, but not as to any restriction of the present utility model.
Embodiment.
The utility model as shown in Figure 1.A kind of drive unit of rotary kiln comprises main motor 1 and main gear reducer 2, and main gear reducer 2 is the dual input shaft reductor; Main motor 1 is connected with one of them power shaft of main gear reducer 2, and the output shaft of main gear reducer 2 is connected with rotary kiln driven wheel 3; It is characterized in that: another power shaft of main gear reducer 2 is connected with accessory drive 5 through mono-directional overrun shaft coupling 6.Described mono-directional overrun shaft coupling 6 comprises by freewheel clutch and yielding coupling and combining.Described accessory drive 5 is provided with two output shafts, and an output shaft is connected with mono-directional overrun shaft coupling 6, and another is connected with holdback 4.
Operation principle of the present utility model
Main gear reducer 2 speed end of the present utility model adopt dual input shaft, and one connects main motor 1, the shaft coupling that another is combined by freewheel clutch and yielding coupling by mono-directional overrun shaft coupling 6() connect an output shaft of accessory drive 5.Accessory drive 5 has two output shafts, except an output shaft that is connected with main gear reducer 2, a holdback 4 is housed on another output shaft.
The course of work of the present utility model is as follows:
Drive main gear reducer 2 by main motor 1 during the rotary kiln operate as normal, at this moment the mono-directional overrun shaft coupling 6 that is connected with main gear reducer 2 of accessory drive 5 is in and surmounts the state of freeing, and accessory drive 5 standbies are static, are not subjected to the driving of main motor 1 and main gear reducer 2;
When main motor 1 breaks down or rotary kiln when needing repairing, main motor 1 is shut down, and changes by accessory drive 5 drive systems, and at this moment the direction that relatively rotates at mono-directional overrun shaft coupling 6 two ends reverses, and causes its inner wedging, thereby as the shaft coupling transferring power.Because the rotating speed of accessory drive 5 is very low, main motor 1 can be followed auxilliary the biography passively and be rotated 5 under the situation of loop disconnection;
When regularly accessory drive being switched on check, do not need to stop the operate as normal of main motor, because the output speed of accessory drive 5 is lower than the rotating speed of main motor 1, mono-directional overrun shaft coupling 6 still is in and surmounts the state of freeing, and two motors can rotate simultaneously and not influence each other;
When two motors did not all drive, the holdback 4 of dress can prevent rotary kiln generation backwards rotation on the accessory drive 5, and at this moment the inside of mono-directional overrun shaft coupling 6 is in the wedging state and transmits stall torque.
Novel drive system can automatically be carried out two switchings that drive, and does not need manually-operated, has improved the automaticity of system.
