Abstract
The utility model relates to a twist-limiting coupling, belonging to a coupling for limiting a motor torque, which comprises components such as flower keyboards, steel balls, end surface bearings, a left coupling, a right coupling, springs, rubber cushion components, etc. compared with the similar domestic products, the coupling has the advantages of compact structure, convenient installation, and convenient adjustment, the coupling can conduct energy buffering and damping for protecting the motor and connecting devices.
Description
The utility model is used for the connection of motor and equipment, belongs to the transmission of power field.
The present coupling that uses has a variety of, and structural type is except that left and right sides shaft coupling is similar substantially, and all the other structures are all had any different.Stack up is said and more advanced is: the fluid coupling that has that can buffer shock-absorbing can play overload protective function again; The novel product elastic dowel pin shaft coupling of Shanghai Red Star machinery plant.Fluid coupling is to realize buffer shock-absorbing and overload protection by fluid power, the product of Shanghai Red Star factory is the rubber parts buffer shock-absorbing, reaches overload protection by cutting off of pin (nonmetallic material).
The purpose of this utility model is that a kind of novel limit of design is turned round coupling; neither do not cut off pin again by fluid power, when the motor overload operation, this limit is turned round coupling can make motor and equipment disengage automatically; allow motor be in the no load running state, play the purpose of protection motor.
Solution of the present utility model is: directly and motor reel (or other live axles) connection be joint sleeve (10), spline on the joint sleeve (10) and flower keyboard (7) engagement, have cone shape hole on flower keyboard (7) and the tie-plate (4), cone shape hole contacts with steel ball (6), flower keyboard (7) drives tie-plate (4) by steel ball (6), thereby drives left and right shaft coupling (2) and (1).The spring (9) on flower keyboard (7) left side is that the end thrust that acts on flower keyboard (7) and the steel ball (6) when turning round for Balancing equipment is established, and end thrust is to determine according to the moment of torsion that motor allows.
Fixed tray (5) is to establish for the position of stationary balls (6).
The end face bearing (3) that is located at joint sleeve (10) right-hand member can be avoided the friction of generation between joint sleeve (10) and the tie-plate (4) when the motor no load running.
Be the load of Regulation spring (9) and the balance of end thrust, establish adjusting nut (8) in the left side of spring (9).
The utility model is owing to adopting cone shape hole and this structural type of steel ball (6), so when overburdening, flower keyboard (7) disengages with steel ball (6), realizes the no load running of motor automatically.Because of establishing end face bearing (3) at the right-hand member of joint sleeve (10), so when the motor no load running, avoided the friction of static element and running part, so both played the effect of protection motor, prevented the damage of coupling and connecting device again.
Accompanying drawing is a structural drawing of the present utility model
Among the figure:
1 → right shaft coupling; 2 → Left-wing Federation joint;
3 → end face bearing; 4 → tie-plate;
5 → fixed tray; 6 → steel ball;
7 → flower keyboard; 8 → adjusting nut;
9 → spring; 10 → joint sleeve;
11 → rubber buffer.
The contrast accompanying drawing further describes below:
The flower keyboard of this coupling (7) contacts under the effect of spring (9) with steel ball (5) with cone shape hole on the tie-plate (4), and drive left and right shaft coupling (2) and (1), behind motor start-up, when the cone shape hole of flower keyboard (7) and tie-plate (4) contacts work with steel ball, produce two component, be peripheral force and end thrust, the work loads of spring (9) is then adjusted balance according to this end thrust.
When breaking down, Operating torque increases, the also corresponding increase of end thrust, when end thrust surpasses the spring work loads, flower keyboard (7) moves to left, and disengages with steel ball (5), and the parts on steel ball this moment (5) the right stop the rotation, motor drives joint sleeve (10) and flower keyboard (7) no load running, thus the motor overload operation prevented; Again because joint sleeve (10) right-hand member has end face bearing (3), so impact and the friction having avoided static element and turned round and produce between the part.
Claims (5)
1, a kind of limit of being made up of Left-wing Federation's joint (2), right shaft coupling (1) is turned round coupling, it is characterized in that: and motor reel links is joint sleeve (10), spline on the joint sleeve (10) and flower keyboard (7) engagement, on flower keyboard (7) and tie-plate (4), be provided with cone shape hole, cone shape hole contacts with steel ball (6), and spring (9) is placed on the left side of flower keyboard (7).
2, limit according to claim 1 is turned round coupling, it is characterized in that: establish fixed tray (5) in the outside of steel ball (6).
