Abstract
The utility model discloses a special solid-state coupler of belt drive, including casing and rotor assembly, rotor assembly one end is located the cavity of casing and passes through the bearing with the casing and be connected, and the other end stretches out outside the casing and is equipped with the belt pulley through the bearing cover, the belt pulley is close to the one end of casing and the cooperation of housing end face and is fixed through screw locking, be equipped with the blade that divides into a plurality of regions such as casing inner cavity on the rotor, all be equipped with the steel ball that quantity is unanimous in every region. The utility model discloses can realize the soft start of area year, and the soft start of area year is close to the no-load start, has reduced required electric current when starting, and when the load was too big, the rotor assembly took place to skid simultaneously, can avoid the too big belt that causes of load to skid, has improved the security of equipment operation.
Description
Technical Field
The utility model belongs to the technical field of the belt drive, concretely relates to special solid-state coupler of belt drive.
Background
The belt transmission is one of mechanical transmission modes, and is widely applied due to simple structure and convenient installation and maintenance. However, the existing soft start belt transmission only has two types, namely electrical soft start and liquid couple soft start, the electrical soft start has low cost performance, a corresponding electric control system needs to be equipped, the liquid couple soft start has the problems of hydraulic oil oxidation and hydraulic oil leakage, and the maintenance cost is high. Therefore, we propose a solid-state coupling dedicated to pulleys that does not change the existing mounting base, mounting habits.
Disclosure of Invention
The utility model aims to solve the technical problem that just not enough to above-mentioned prior art provides a special solid-state coupling of belt drive, and it can reduce the electric current that the belt carried and start, and accessible no-load starts, does not need the accommodate motor position and changes the motor base simultaneously, and possesses higher security.
The utility model adopts the technical proposal that: the utility model provides a special solid-state coupler of belt drive, includes casing and rotor assembly, rotor assembly one end is located the cavity of casing and passes through the bearing with the casing and be connected, and the other end stretches out outside the casing and is equipped with the belt pulley through the bearing cover, the belt pulley is close to the one end of casing and casing terminal surface cooperation and is fixed through screw locking, be equipped with the blade that divides the cavity etc. in the casing into a plurality of regions on the rotor, all be equipped with the steel ball of quantity unanimity in every region.
Preferably, a bushing is further arranged between the bearings for supporting the belt pulley, and the bushing is sleeved on the rotor assembly.
The utility model discloses can realize the soft start of area year, and the soft start of area year is close to the no-load start, has reduced required electric current when starting, and when the load was too big, the rotor assembly took place to skid simultaneously, can avoid the too big belt that causes of load to skid, has improved the security of equipment operation.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. a housing; 2. a rotor assembly; 3. a belt pulley; 4. a blade; 5. and (5) steel balls.
Detailed Description
The present invention will be described in further detail with reference to the drawings and specific embodiments.
Examples
As shown in fig. 1, the special solid-state coupler for belt transmission provided by this embodiment includes a housing 1 and a rotor assembly 2, the housing 1 is mounted at one end of the rotor assembly 2 through a bearing, and the housing 1 and the rotor assembly 2 are fixed through a bearing end cover, the other end of the rotor assembly 2 is located outside the housing 1 and is sleeved with a belt pulley 3 through a bearing, one end of the belt pulley 3 far away from the housing 1 is fixed with the rotor assembly 2 through the bearing end cover, the belt pulley 3 and the rotor assembly 2 are supported through a bearing, and a bushing is sleeved between the two bearings, one end of the belt pulley 3 close to the housing 1 is matched with the end surface of the housing 1 and is fixed through a screw lock, blades 4 which equally divide the cavity in the housing 1 into a plurality of regions are arranged on the rotor, and steel balls 5 with the same number are arranged in each region.
The theory of operation, the motor drives rotor assembly 2 and rotates, casing 1 and belt pulley 3 are motionless this moment, rotor assembly 2 rotates and makes blade 4 drive steel ball 5 move in casing 1, steel ball 5 receives centrifugal force, paste tight casing 1 inner wall, when rotor assembly 2's rotational speed constantly improves, steel ball 5 receives centrifugal force bigger and bigger, the frictional force between steel ball 5 and the shell will be bigger and bigger, when moment that frictional force produced can drive belt pulley 3 and rotate, belt pulley 3 will rotate, the frictional force that steel ball 5 and shell produced makes casing 1 rotatory promptly, thereby drive belt pulley 3 of being connected with casing 1 and rotate, along with the invariant of motor speed, belt pulley 3 and rotor assembly 2, casing 1 reaches synchronous revolution, thereby the working machine is normally rotatory.
The above is only the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any modification and replacement based on the technical solution and the utility model provided by the present invention should be covered within the protection scope of the present invention.
Claims (2)
