Abstract
The utility model discloses a kind of adjustment-free brakes for lift dragging main machine, host engine base, brake and friction plate including mating connection, it is connected by one group of connector of setting between the brake and the host engine base, gasket group is arranged on the connector, the gasket group is abutted with the end face of host engine base and brake respectively.The utility model is compared with prior art, after friction disc wear, the distance between brake and host engine base can be reduced as long as removing the gasket on connector, and then make the utility model in the braking state under, the distance between brake and friction plate are still maintained between 0.2 0.5mm, avoid that distance between brake and friction plate is excessive to be led to the problem of, and this regulative mode is very convenient, because friction plate thickness is certain, the precision adjusted is also high.
Description
Technical field
The utility model belongs to brake technical field, and in particular to a kind of adjustment-free for lift dragging main machine is braked
Device.
Background technology
Driving part of the traction machine as elevator is the device for driving the car of elevator and counterweight to run up and down, it
It is mainly made of components such as motor, brake, traction sheaves, safety component of the brake as elevator, is to ensure elevator safety
The basic device of operation, elevator is using machine-electricity friction-type normally closed brake, when elevator does not work, brake, and electricity
When ladder operation, brake declutches, and when elevator brake, by the effect of mechanical force, makes friction plate and braked wheel friction and generates system
Kinetic moment；When elevator moves row, brake is set to declutch by electromagnetic force.
When brake declutches, there are the working clearance of 0.2-0.5mm between friction plate and brake, and brake and master
The distance between machine engine base be it is fixed, due to friction plate be by with the braked wheel friction on host, promote elevator brake, institute
It is very easy to abrasion with friction plate, working clearance when causing in the braking state between friction plate and brake becomes larger, so that
A series of problems is brought, such as：Electromagnetic force is not enough, friction plate stroke becomes larger, braking time generates error etc..Under normal conditions,
Staff reduces the distance between brake and host engine base by twisting the screw on brake, so adjust brake and
The working clearance is maintained at 0.2-0.5mm between friction plate, however this adjustment mode needs to adjust multiple screws on brake,
Speed is slow, adjustment trouble, and precision is low.
Utility model content
In order to make up for the deficiencies of the prior art, the utility model provides a kind of adjustment-free braking for lift dragging main machine
Device technical solution.
A kind of adjustment-free brake for lift dragging main machine, including the host engine base of mating connection, braking
Device and friction plate, it is characterised in that coordinated by one group of connector of setting between the brake and the host engine base and connected
It connects, gasket group is arranged on the connector, the gasket group is abutted with the end face of host engine base and brake respectively.
A kind of adjustment-free brake for lift dragging main machine, it is characterised in that the brake and friction plate
Between setting friction plate base, friction plate with friction plate base be fixedly connected, rub plate base be fixedly connected with one group of bolt, it is described
Bolt passes through friction plate base and brake, rubs between plate base and brake and has gap.
A kind of adjustment-free brake for lift dragging main machine, it is characterised in that the friction plate and the system
Spring is set between dynamic device.
A kind of adjustment-free brake for lift dragging main machine, it is characterised in that the spring is set in described
On bolt.
A kind of adjustment-free brake for lift dragging main machine, it is characterised in that the gasket group includes 2-8
A gasket.
A kind of adjustment-free brake for lift dragging main machine, it is characterised in that the gasket group includes 5
Gasket.
A kind of adjustment-free brake for lift dragging main machine, it is characterised in that the spacer thickness is
0.05-0.15mm。
A kind of adjustment-free brake for lift dragging main machine, it is characterised in that the spacer thickness is
0.1mm。
A kind of adjustment-free brake for lift dragging main machine, it is characterised in that the connector is screw.
The utility model compared with prior art, after friction disc wear, can subtract as long as removing the gasket on connector
The distance between small brake and host engine base, so make the utility model in the braking state under, between brake and friction plate
Distance be still maintained between 0.2-0.5mm, avoid that distance between brake and friction plate is excessive to be led to the problem of,
And this regulative mode is very convenient, because friction plate thickness is certain, the precision adjusted is also high.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the utility model section structural schematic diagram.
Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings.
As illustrated in fig. 1 and 2, a kind of adjustment-free brake for lift dragging main machine, includes the host machine of mating connection
Seat 1, brake 2 and friction plate 3, setting friction plate base 8, friction plate 3 and friction plate between the brake 2 and friction plate 3
Substrate 8 is fixedly connected, and friction plate base 8 is fixedly connected with one group of bolt 6, preferably a bolt 6, and bolt 6 passes through friction chip base
Plate 8 and brake 2 are simultaneously fixed using nut, rub and have gap between plate base 8 and brake 2 by pulling bolt 6, make spiral shell
Bolt 6 is with movable friction plate substrate 8 and friction plate 3, it can be achieved that hand declutches.
It is connected by one group of connector 4 of setting between the brake 2 and the host engine base 1, the connector 4
For screw, it is arranged gasket group 5 on the connector 4, end face of the gasket group 5 respectively with host engine base 1 and brake 2 is supported
It connects.Specifically, opening up threaded hole on the end face of host engine base 1, connector 4 is threadedly coupled across brake 2 with threaded hole, pad
Piece group 5 is set in the bar portion of connector 4, and the nut of connector 4 is located at 2 outer end face of brake.
In the present invention, spring 7 is set between the friction plate 3 and the brake 2, and the spring 7 is set in
On the bolt 6.
