Abstract

The utility model provides an elevator door motor is with tight device that rises, whole device is established on the tight frame that rises, fixing bolt passes through the nut, the packing ring is fixed and is tightly put up the left end rising, the staff that passes the tight frame that rises through the connection of outer retaining ring and tightly puts up both sides, fix antifriction bearing in the hold -in range accessory whorl through the end ring, the hold -in range accessory whorl passes through antifriction bearing and little hub connection, the cover is on the medial surface is tightly put up to rising to little epaxial axle sleeve one end, the other end supports on antifriction bearing's terminal surface, the hold -in range accessory whorl passes through the hold -in range and is connected with the action wheel, compared with the prior art, the tight device that rises of post assembling rotates the piece and rotates in a flexible way, do not have the card and hinder the phenomenon, the stoppage in transit trouble of door machine has been reduced, the service life of the door machine is prolonged the time elevator performance and precision obtain effectual improvement, make the enterprise reduce the quick -witted manufacturing cost of door, improve internal elevator operation's stationarity, the security, productivity is increased, and the economic benefit is improved.

Description

A kind of elevator door machine swelling device

Technical field

The utility model is a kind of elevator door machine swelling device, refers to elevator design manufacture Technical field, specifically refers to elevator door-motor tensioner technical field.

Background technology

Domestic, elevator expansion apparatus is applied to elevator, is the important set composition of elevator, from domestic Since introducing elevator, a lot of key components and parts derive from import, due to elevator expansion apparatus Reason, tumbler is dumb, jam phenomenon occurs, often makes elevator door-motor break down and stop Fortune, or cause elevator conveying unstable, furthermore the structure of import elevator expansion apparatus is complicated, dimension Repair difficulty, it is difficult to improve performance and the precision of elevator, add people to taking elevator safety sense Worry.

Utility model content

The purpose of this utility model is to overcome drawbacks described above, is improved prior art, if A kind of simple in construction of meter, goes slick, and will not produce a kind of elevator door machine tensioner dress of jam Put.

Its technology is achieved in that and includes fixing bolt, nut, packing ring, little axle, synchronization Band accessory whorl, end ring, rolling bearing, axle sleeve, outer back-up ring, tensioner frame, Timing Belt, its Being characterised by: whole device is located on tensioner frame, fixing bolt is fixed on by nut, packing ring Tensioner frame left end, the little axle through tensioner frame connects tensioner frame both sides by outer back-up ring, passes through axle Hold back-up ring to be fixed on by rolling bearing in Timing Belt accessory whorl, Timing Belt accessory whorl by rolling bearing with Little axle connects, and the axle sleeve one end being enclosed within little axle is against on tensioner frame medial surface, and the other end is against On the end face of rolling bearing, Timing Belt accessory whorl is connected with driving wheel by Timing Belt.

Described tensioner frame is shaped as the structure of U-shaped.

Implement the obvious advantage after this technology and effect is: compared with prior art, after assembling Swelling device tumbler rotates flexibly, without jam phenomenon, decreases the fault of stop of a machine, carries While high door machine service life, performance and the precision of elevator are effectively improved, and make enterprise Reduce a machine production cost, improve domestic elevator traveling comfort, security, Improve production capacity, improve economic benefit.

Accompanying drawing explanation

Fig. 1 is main TV structure schematic diagram of the present utility model,

Fig. 2 is the plan structure schematic diagram of the external Timing Belt of the utility model.

Wherein, 1-fix bolt, 2-nut, 3-packing ring, the little axle of 4-, 5-Timing Belt accessory whorl, The outer back-up ring of 6-end ring, 7-rolling bearing, 8-axle sleeve, 9-, 10-tensioner frame, 11-synchronize Band.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is further described:

Seeing accompanying drawing 1,2, whole device is located on tensioner frame 10, fixing bolt 1 by nut 2, Packing ring 3 is fixed on tensioner frame 10 left end, and the little axle 4 through tensioner frame 10 is connected by outer back-up ring 9 Tensioner frame 10 both sides, are fixed on rolling bearing 7 in Timing Belt accessory whorl 5 by end ring 6, Timing Belt accessory whorl 5 is connected with little axle 4 by rolling bearing 7, axle sleeve 8 one end being enclosed within little axle 1 Being against on tensioner frame 10 medial surface, the other end is against on the end face of rolling bearing 7, and Timing Belt is secondary Wheel 5 is connected with driving wheel by Timing Belt 11.

Described tensioner frame is shaped as the structure of U-shaped.

Seeing accompanying drawing 1,2, whole device is fixed on a machine by fixing bolt 1.By automatically Controlling, start motor and make driving wheel rotate, the driving wheel of rotation drives Timing Belt 11 to make Timing Belt Accessory whorl 5 synchronous rotary, drives the motion of door machine, auto-open-close elevator door.

Claims

1. an elevator door machine swelling device, including fixing bolt, nut, packing ring, little axle, with Step band accessory whorl, end ring, rolling bearing, axle sleeve, outer back-up ring, tensioner frame, Timing Belt, It is characterized in that: whole device is located on tensioner frame, fixing bolt is fixed by nut, packing ring At tensioner frame left end, the little axle through tensioner frame connects tensioner frame both sides by outer back-up ring, passes through Rolling bearing is fixed in Timing Belt accessory whorl by end ring, and Timing Belt accessory whorl passes through rolling bearing Being connected with little axle, the axle sleeve one end being enclosed within little axle is against on tensioner frame medial surface, and the other end supports On the end face of rolling bearing, Timing Belt accessory whorl is connected with driving wheel by Timing Belt.

A kind of elevator door machine swelling device the most according to claim 1, it is characterised in that: institute The tensioner frame stated is shaped as the structure of U-shaped.
