Abstract
The utility model discloses an elevator layer door change speed gear and link plate connection structure, including link plate and change speed gear, the link plate is L shape structure, waist type hole has been seted up on link plate upper portion, pass a connecting axle in the inside bearing of change speed gear, adopt interference fit to be connected between connecting axle and the bearing, connecting axle nose fixes and has cup jointed an axle sleeve, the axle sleeve front end set up into with waist type hole matched with waist type structure, the connecting axle pass waist type hole on the link plate with change speed gear fixed mounting on the link plate. Adopt the connected mode of this kind of structure, under the condition that layer door change speed gear damaged, can directly dismantle the separation with change speed gear and layer door strap, only change the change speed gear can, can not involve the link plate, made things convenient for dimension guarantor person's work.
Description
Technical field
The utility model relates to a kind of elevator door change gear and link plate connection structure, belongs to elevator technology field.
Background technology
Because the population density in city increases, office raises all the more with the floor of house, and the Occupation coefficient of elevator also increases, and general layer door gear all can have passed through 1,000,000 commissioning tests to check its in-use performance before using.But change gear remains easy loss product on layer door gear, use meeting wearing and tearing slowly at any time, may wear to certain degree just to need to change, and existing commercially a large amount of layer door change gear is all adopt the connection mode of revolving riveting with link plate, need special equipment (riveter) to make, when revolving riveting also can at substantial artificial, cannot dismantle during replacing, need to change whole link plate, replacement cost is very high.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of when elevator door change gear damages, can change change gear separately, need not change the connection structure of link plate.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of elevator door change gear and link plate connection structure, comprise link plate and change gear, described link plate is L shape structure, described link plate top offers waist-shaped hole, through an adapter shaft in described change gear internal bearings, described adapter shaft is connected with adopting interference fit between bearing, described adapter shaft sponson fixed cover is connected to an axle sleeve, described axle sleeve front end is set to the waist type structure matched with waist-shaped hole, change gear is fixedly mounted on link plate through the waist-shaped hole on link plate by described adapter shaft.
As preferably, the rear end of described axle sleeve is provided with the shaft shoulder, and the width of the described shaft shoulder is equal with the thickness of link plate.
As preferably, described adapter shaft divides the screw thread being provided with M10 for the shaft head connected.
As preferably, the width of described axle sleeve front end waist type structure is equal with the thickness of link plate.
As preferably, described shaft shoulder rear end 1/3rd extend into change gear inside.
Compared with prior art, usefulness of the present utility model is: the connection mode adopting this structure, when layer door change gear damages, directly change gear can be dismantled with layer door hanging plate and be separated, only change change gear, can not link plate be related to, facilitate the work of repair and maintenance personnel.

detailed description of the invention:
Below in conjunction with the drawings and the specific embodiments, the utility model is described in detail:
A kind of elevator door change gear as shown in Figures 1 to 6 and link plate connection structure, comprise link plate 1 and change gear 2, described link plate 1 is L shape structure, described link plate 1 top offers waist-shaped hole 11, through an adapter shaft 3 in described change gear 2 internal bearings 21, described adapter shaft 3 adopts interference fit to be connected with between bearing 21, described adapter shaft 3 sponson fixed cover is connected to an axle sleeve 4, described axle sleeve 4 front end is set to the waist type structure matched with waist-shaped hole 11, and change gear 2 is fixedly mounted on link plate 1 through the waist-shaped hole on link plate 1 top by described adapter shaft 3.
The rear end of described axle sleeve 4 is provided with the shaft shoulder 5, and the width of the described shaft shoulder 5 is equal with the thickness of link plate 1.
Described adapter shaft 3 divides the screw thread being provided with M10 for the shaft head connected.
The width of described axle sleeve 4 front end waist type structure is equal with the thickness of link plate 1.
It is inner that the described shaft shoulder 5 rear end 1/3rd extend into change gear 2.
It is emphasized that: be only preferred embodiment of the present utility model above, not any pro forma restriction is done to the utility model, every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
