Abstract
The utility model discloses a speed change mechanism seat assembly of an excavator, which aims to solve the problem that when the speed change mechanism seat assembly of the existing excavator is assembled, a contact on a signal collector is difficult to fall into a hemispherical groove on a gear shifting shaft, so that production efficiency is affected.
Description
Technical Field
The utility model relates to a speed change mechanism, in particular to an excavator speed change mechanism seat assembly which consists of a speed change mechanism seat, a gear shifting shaft, a gear selecting shifting head, a gear selecting shaft, a spring, a gear shifting arm and a gear selecting arm.
Background
Chinese patent CN218510152U discloses such an excavator speed change mechanism seat assembly, which is structurally characterized in that: the gear shifting mechanism comprises a speed changing mechanism seat, a gear shifting shaft, a gear shifting head, a gear shifting shaft, springs, a gear shifting arm and a gear shifting arm, wherein the gear shifting mechanism seat can be arranged on a gear shifting shaft of an excavator, the gear shifting head is arranged on the gear shifting shaft in the speed changing mechanism seat, the springs are respectively sleeved on the gear shifting shafts at the two ends of the gear shifting head, one end of the gear shifting shaft extends out of the speed changing mechanism seat and is connected with the gear shifting arm, the gear shifting shaft is arranged in the speed changing mechanism seat vertically to the gear shifting shaft, the upper end of the gear shifting shaft extends out of the speed changing mechanism seat and is connected with the gear shifting arm, and a signal collector is arranged on the speed changing mechanism seat at the other end of the gear shifting shaft and passes through the speed changing mechanism seat to be in contact with the other end of the gear shifting shaft. The hemispherical groove which can be contacted with the signal collector is formed in the outer circle surface of the other end of the gear shifting shaft. Therefore, during assembly, the contact on the signal collector is difficult to fall into the hemispherical groove on the gear shifting shaft, so that the production efficiency is affected.
Disclosure of Invention
The utility model aims to provide the speed change mechanism seat assembly of the excavator, which can enable a contact on a signal collector to quickly fall into a hemispherical groove on a gear shifting shaft, improves the production efficiency and is convenient to maintain.
The utility model provides a speed change mechanism seat assembly of an excavator, which comprises a speed change mechanism seat, a gear change shaft, a gear selection shifting head, a gear selection shaft, springs, a gear change arm and a gear selection arm, wherein the speed change mechanism seat can be arranged on a speed change box of the excavator.
And a semi-cylindrical groove which is contacted with the signal collector is arranged on the outer surface of the positioning ring.
The other end of the gear shifting shaft is provided with a screw tooth which can be matched with a fastener.
After the structure is adopted, the signal collector passes through the speed change mechanism seat to be in contact with the positioning ring sleeved at the other end of the gear shifting shaft, and the positioning ring is connected with the gear shifting shaft through the fastener. During assembly, only the positioning ring is required to be rotated, so that the contact on the signal collector falls into the semi-cylindrical groove on the outer surface of the positioning ring, and then the fastener on the gear shifting shaft is locked. Therefore, the aims of enabling the contact on the signal collector to quickly fall into the hemispherical groove on the gear shifting shaft, improving the production efficiency and being convenient to maintain are achieved.
